How do you know if a milk tooth is. How to distinguish a milk tooth from a molar

As you know, teething is a rather complicated process that causes quite a lot of trouble. At the beginning, the baby's milk teeth appear. Over time, they are replaced by permanent molars. Such a process of change has its own characteristics.

With the growth of molars, maximum efforts must be made so that they grow even and healthy. Here you need to pay attention to some factors. First of all, this concerns the timely change of teeth.

People are used to solving all problems with their teeth with the help of dentists and an orthodontist. Of course, contacting specialists is a rather important process. But, some issues can be solved independently.

This is especially true for changing teeth. With certain information, even the parents themselves can easily determine which teeth their children have: milk or permanent, and how to distinguish them from each other.

Meet milk teeth

The first teeth in a child begin to form in the first trimester of the mother's pregnancy. Therefore, during this period, doctors recommend paying special attention to the diet. Of course, milk teeth erupt much later after the birth of the child.

Most often, this period occurs during the child's first significant movements. In this case, the child may have a fever, and the gums may swell.

At one and a half to two years, the child already has all the milk teeth, they are somewhat smaller and have a different shape than the molars. Their peculiarity lies in the unique bluish tint.

Permanent teeth have a yellowish-gray tint. At the age of six, milk teeth begin to be actively replaced by molars.

In any case, care should be taken for both permanent and milk teeth. Proper nutrition, hygiene and regular visits to a specialist will ensure the formation of a normal bite.

On an ongoing basis

By the age of 6, the first molars appear in the child. There are 12 molars, 6 for each jaw. The peculiarity of the upper molars is their large size and high strength. They have 3 roots that diverge in different directions. This ensures their secure fastening and resistance to loads.

When a molar tooth appears, the milk teeth naturally fall out. But, sometimes there are exceptions. So, it happens that milk has not yet fallen out, and permanent teeth are already ready to take their place.

In such cases, the child experiences pain and discomfort. In this case, it is better to immediately seek help from a specialist.

Timely assistance will help prevent the curvature of a new tooth. The molars perform an important function, which is to crush food. This is due to the four tubercles on its surface.

Throughout their lives, they must be carefully looked after. This will preserve their integrity and functioning. Otherwise, you cannot do without the help of specialists.

When you can not do without the help of a doctor

Often, changing teeth is almost painless. When teeth fall out on their own, there is no pain. But, there are exceptions.

So, if a child has severe pain, itching, the temperature rises or the sensitivity of the enamel increases, then you should immediately seek help from a doctor. Also, a profuse hemorrhage at the site of a recently fallen milk tooth should alert.

If a permanent tooth does not appear in place of the milk that has fallen out, then you need to contact a dentist. The fact is that treatment may be needed here.

Also, in some cases, inflammatory processes and other complications may occur that will cause discomfort and pain to the child. An equally important problem is the incorrect growth of the tooth. In the future, this negatively affects the bite.

In fact, the change of bite is a natural process. If this does not cause pathologies and symptoms, then you should not worry.

If, when changing the bite, the temperature rises and the child becomes too irritable, then you need to seek help from a specialist. This will quickly solve the problem and prevent complications.

Milk and molars have many differences. First of all, it is worth noting that milk teeth are temporary, over time they fall out, and teeth take their place. The process takes place with some effort.

First of all, the roots of permanent teeth grow. They push milk through the dental canals. Also, a permanent tooth, growing, rests against a milk tooth, which creates an additional force that pushes it out.

Of particular importance are special cells that destroy the roots of milk teeth. As a result, they lose their grip on the jaw. The root becomes thin and long. This form accompanies the extrusion of a milk tooth under the influence of previous factors.

If the tooth itself does not fall out for one reason or another, then it can be easily removed with the help of dental instruments.

You can also distinguish between teeth by number. First of all, it is worth noting that an adult has 32 molars.

Their roots bend and diverge, which provides a secure attachment to the jaw. Milk teeth have a characteristic shape. In the cervical part of the tooth, a pincushion-shaped thickening can be observed.

Another characteristic difference is the inclination of the longitudinal axis of the crowns to the tongue and palate. Most often, it is this inclination that makes it possible to distinguish milk teeth from molars.

In the photo, the boy's milk teeth have not yet fallen out, and the permanent teeth are already being cut.

You can also distinguish between teeth by shade. The baby's first teeth are white with a slight bluish tinge. As for the indigenous ones, they have a yellowish-grayish tint. The neck of the tooth is darker.

It is also worth noting that milk teeth are less hard than permanent teeth. They are easily amenable to drilling and other manipulations carried out by the dentist for the purpose of treatment.

With this information, each parent can easily recognize which tooth is growing in a child. In the future, this will allow for careful monitoring of changes in the bite.

Thanks to this, there is every chance that the child gets a healthy and beautiful smile. If you suddenly determine that a milk tooth cannot leave the dental canal, then you should immediately seek help from a doctor. This will avoid many problems, including the occurrence of pain and malaise in the child.

How to distinguish a milk tooth from a molar?

The process of the appearance of teeth in a child is always interesting to parents, so they keep track of which milk ones have fallen out and which permanent ones have come out. However, there are situations when it is not clear whether this is still a milk tooth in the mouth of a toddler or already a root. How are they different and how can you recognize them?

This is the name of the first teeth that appear in a baby under the age of 2.5-3 years. They begin to erupt in most babies at 6 or 7 months, when the first central incisor “pecks” on the lower jaw of the baby. Soon his “partner” also comes out, after which the incisors on the upper jaw, the lateral incisors below, the first molars, canines and second molars are cut, until the child has 20 teeth.

This amount will remain until about 5-6 years, after - the time will come for the eruption of the first molars.

Change of milk teeth to molars begins at the age of 6-7 years

This is the name of the permanent teeth, which begin to be cut at an average of 6-7 years of age. The first of the molars to erupt, occupying the sixth place in the dentition, and only after that the milk teeth begin to fall out, and in their place their permanent replacement begins to be cut. At the same time, there are more molars - there are 32 of them in total, although in most cases only 28 of them erupt in childhood.

The last four (“wisdom” teeth) appear later than the others, sometimes even over the age of 30-40 years.

If a child's milk teeth erupt only 20, then the molars will have at least 28

It is possible to determine whether a tooth belongs to milk teeth or to indigenous teeth by its:

Size and form. Temporary - small in size and more rounded, and indigenous - larger.
Coloring. The color of milk teeth is often white with an indistinct blue tint, and permanent ones, due to the presence of more mineralized tissues, are distinguished by a yellowish tint of enamel.
Location. The growth of dairy occurs vertically, and the molars are slightly directed with their crowns outward to the lips and cheeks.

Let's take a closer look at how to understand whether a baby tooth is in the baby's mouth or is already permanent, taking into account its serial number in the dentition (the number is counted from the midline outward):

If the tooth is the sixth or seventh, then it is the root, because there will be only five milk teeth on each side of the jaw.
If you are looking at the fourth and fifth tooth, pay attention to the crown. Milk teeth in this place are distinguished by wider crowns and the presence of four chewing tubercles. If these are already permanent teeth, which are called premolars, they will differ in a smaller number of cusps (there are only two of them on each tooth) and narrower crowns. In a disputable situation, the tooth is compared with a similar one on the other side of the dental arch.
When deciding whether a third tooth (canine) is permanent or milk in a child, its shape and size should also be taken into account. Milk fangs are smaller, and by the time of the physiological change, their sharp tips are worn out. The permanent canine teeth are longer, and their tubercle has a distinct pointed apex.
Looking closely at the incisors (the first and second teeth), first of all, their size is also taken into account. If they are temporary, they are about 4-5 mm wide and about 5-6 mm high. In permanent incisors, the width of the crowns is greater - about 10 mm at the central and about 6-8 mm at the side. In addition, at the age of eruption of permanent incisors, their cutting edges are uneven (with small tubercles), while in milk incisors, by this age, the edge will always be smooth and even.

In order for a child to have molars, absolutely all milk teeth must fall out. Some mothers think that milk molars, due to their large size, are permanent and do not fall out, but this is not so. They will also fall out in due time, allowing the permanent premolars and molars to erupt.

Wisdom teeth are the four teeth that erupt last. According to their location in the dentition, they are also called "eights". Since they represent the 29th, 30th, 31st, and 32nd teeth in a person's mouth, there is no way they can be milk teeth, because there are only twenty milk teeth. In addition, they are cut at the age of over 17 years, when not a single milk tooth should normally remain in the child's mouth.

Wisdom teeth are undoubtedly molars

The situation when the molar tooth has already “hatched”, and the milk tooth is in no hurry to fall out is not uncommon. In this case, you should wait a while, allowing the milk tooth to loosen and leave the dentition.

If more than three months have passed since the appearance of a permanent tooth, and the milk remains in the gum, it is worth going with the child to the dentist.

Starting from the age of five, the roots of milk teeth begin to dissolve. This process takes quite a long time, for example, the root of each incisor resolves within two years, and it takes about three years for the complete resorption of the roots of molars. However, all roots dissolve sooner or later, and only after that the teeth fall out, so they cannot remain in the gum.

Roots of milk teeth dissolve over time

In controversial situations, when it is difficult to determine whether a milk tooth or already a root one, an X-ray examination is recommended. For example, using this research method, you can decide how to treat it or why its change to a permanent one is late. On the x-ray you can see:

The length of the roots, which will be shorter in milk teeth.
The presence or absence of tooth germs under milk teeth.
The location of the cutting molar (it affects the correct position after eruption).

How to distinguish a milk tooth from a molar

Parents whose children are at the age of 6 need to know how to distinguish a milk tooth from a permanent one. Change of bite is a natural process in the body, every child goes through this stage in the process of growing up. But not everyone has a change without complications, therefore, in order to control the process and avoid serious problems, you need to understand the difference between molars and milk molars. To do this, you need to understand the nature of both.

The first bite

Milk teeth are formed in the gums of the child while still in the womb. They erupt much later - starting at the age of 6 months. Often the appearance of the first elements of the future jaw is associated with a certain physical activity of the child, the first attempts to get up and walk. The appearance of the first incisors can cause discomfort to the child, sometimes the temperature rises or the gums become inflamed.

Surprisingly, already during the appearance of the first bite, the rudiments of a permanent one develop in the gums! This is why parents should pay close attention to oral health. Outdated beliefs that primary molars do not need to be treated because they will fall out anyway can lead to undesirable consequences. Deep caries will not only create extremely painful sensations, but can also lead to damage or disruption of the development of the rudiments of the molar located in the gum.

The enamel of the milk elements of the jaw is much thinner and more vulnerable than that of the permanent ones, therefore, in appearance, the milk molar has a bluish tint and is not as saturated white as the permanent one. Such molars are easier to treat, the drill enters them easily. However, the vulnerability of enamel leads to easy spread of caries. It happens that the milk molars in children completely rot, in their place there are black "stumps". The hygiene of the milk bite is very important, parents should teach the child to brush their teeth 2 times a day as early as possible, it is necessary to limit the amount of sweets consumed.

Change of bite

The milk bite has 20 elements, 10 each on the upper and lower jaws. The first permanent elements appear at the age of 6–7 years, simultaneously with the loss of the first milk incisor. The first root molar does not wait until a place is vacated for it, but grows as the sixth in a row in the existing row of teeth, complementing it. And there are 8-12 such molars that grow once and for all. Thus, regardless of the prolapse of the anterior elements of the jaw for parents, the signal for the eruption of permanent teeth is the appearance of “sixes”. Sevens and the so-called "wisdom teeth" also immediately grow permanent. Therefore, at the beginning of the process of changing the bite, it is easy for parents to determine where which teeth are: milk teeth are 20 elements that are in the mouth of a child up to the age of six, molars appear additionally, they are sixth, seventh and eighth in a row in the jaw.

The body provides a mechanism that provides a replacement bite. The shallow and fragile roots of the milk elements of the jaw begin to gradually become thinner and dissolve in the gum. It becomes much more difficult for the incisor to stay in the hole, and, pushed from below, it gradually crawls out of the gum. In order not to delay the process of the appearance of a permanent bite element, children can loosen their teeth, ready to fall out. It is useful during this period to eat solid food, which will naturally renew the bite. After the socket is released, the gum may bleed a little. It is better at this time to refrain from eating for several hours and hold a piece of sterile cotton wool on the wound. In a few hours, a protective plug forms in the hole, which will prevent the penetration of bacteria into the gum.

The 20 bite elements at the front of the jaw are milky and must fall out to make room for the permanent ones. The root element usually appears almost immediately after the loss of its predecessor, because it is he who pushes him out of the gum. In the event that the milk incisor did not have time to leave its place, the permanent one can change the direction of its growth, which in the future will seriously affect the bite as a whole. When a root incisor appears before the hole is released, you should immediately contact your dentist. The doctor will remove the delayed element and determine measures to correct the growth of a new one.

Features

Change of bite occurs gradually and is completed by about 14 years. The exception is the third molars, the last in the row, or, as they are also called, "wisdom teeth". They grow into adulthood from 17 to 21 years and later. Often these molars remain under the surface of the gums and do not show up on the surface. During the period of active bite replacement, it is difficult for parents to remember which element of the first 20 has changed and which has not yet. How to determine whether a milk molar or root? The distinguishing features of temporary and permanent molars will help.

Visual differences between milk teeth and permanent teeth are as follows:

permanent molars have an angle of inclination with respect to the gum, their tops should be directed towards the cheeks, temporary ones stand straight in the gum;
permanent elements of the jaw have branched and deep roots, while temporary roots are shallow and small;
milk has a thickening at the point of contact with the gum;
the temporary crown has a more round shape;
the milk molar has a blue tint due to the small thickness of the enamel, the permanent one has a yellowish color;
the neck of the root is darker than the crown;
the surfaces of permanent molars are distinguished by the fact that, as a rule, they contain 4 tubercles necessary for successful chewing of food.

In the event that it is not possible to visually determine the type of tooth, it is recommended to take an x-ray of the jaw. For example, a permanent upper molar will have a triple root that will extend deep into the periosteum.

In the region of the root of the milk incisor, during the replacement period, the rudiment of the root will be visible. The root will be thin and small. The appearance of a permanent element of the jaw may be delayed, but in this case, the milk tooth is still easy to determine by the characteristics of the root. Pulling out a milk tooth in the absence of a permanent element in the gum is not recommended, it is necessary to maintain it in a healthy state. Conversely, if a permanent element has already formed in the jaw, and the temporary one does not fall out, removal may be necessary.

A situation is possible when the milk molar fell out, and the permanent one does not come out for several months. In this case, the molars, under pressure from each other and from the process of chewing food, begin to move to a free place. The bite changes, the free space may disappear completely, and there will be no room left for the growing molar and it will also grow in the wrong place. The problem can be solved with the help of prosthetics.

Constant bite

There are 32 elements in the permanent occlusion of an adult, and each of them is very firmly held in the gum and periosteum due to roots that diverge in different directions. Due to this structure of the roots, the molars are able to withstand a significant load during chewing. Caries in the enamel of the permanent molar will develop more slowly than in the milk. But even in the dentist's office, it will take much more time to drill a hole and put a seal. It should be noted that when the molar first appeared, its enamel is thin, and only with time does it thicken. Therefore, during the teething period, it is necessary to carefully monitor oral hygiene.

The difference between milk teeth and permanent teeth is that they perform their functions temporarily. Therefore, temporary occlusion is more vulnerable to diseases and requires a responsible attitude and careful care. It must be remembered that the beauty of a smile in adulthood will largely depend on the health of the milk bite and the correct process of changing it.

How to recognize a molar or milk tooth

Teething is a complex process that gives children and their parents a lot of trouble and anxiety. Someone has a fever, inflammation, nasal congestion during their eruption, and someone endures the change of a milk tooth without any symptoms.

Many parents are concerned about the question of how to distinguish a milk tooth from a permanent one, and in what period this can happen.

Features of the appearance of indigenous units

In almost all children, milk teeth begin to erupt from the age of six months, which eventually change to molars. The replacement process is characterized by a number of specific features. And in order for the molars, which will serve a person regularly for a lifetime, to remain healthy, even, beautiful, parents need to monitor the oral cavity during the shift.

It is advisable to seek help from dentists and orthodontists to understand the timeliness of events for the change of teeth and the correctness of their growth. And, if you have information that will help determine a milk tooth or a molar, some points can be solved independently.

In children, the first milk teeth begin to erupt from 6 months.

The period is characterized by the first movements that the growing baby makes. During teething, babies often have a fever, swelling of the gums. By the age of two, most children have almost all milk teeth, different in size, shape, and they also have a unique bluish tint. This factor distinguishes them from indigenous units, which are a shade of yellowish gray.

Milk teeth are usually actively replaced by molars by the age of 6. But you should take care of your teeth at any period of their development, including monitoring nutrition, hygiene, and regular visits to dentists to ensure bite formation. Milk teeth are also subject to various dental diseases, such as pulpitis, caries, which must be treated.

The main differences between permanent teeth and milk teeth are:

the dental crown is determined by different sizes, in particular, the shape of the milk tooth has a large roundness, and in the place of the cervical part there is an enamel roller;
milk teeth have a bluish tint due to the low mineralization of dentin, enamel, as well as a smaller thickness. Permanent teeth are distinguished by a yellowish tint;
the crown of the permanent unit has an inclination towards the lips and cheeks, and the milk ones grow in a vertical position;
the difference in appearance can also be determined by the serial number of the dental arch, where the reference originates from the midline, as:

Of particular importance is cellular special structures capable of destroying temporary roots that lose their grip and strength in the jaw. If it is impossible to fall out on their own, they are eliminated with the help of dental instruments.

It should be noted that the question of whether all milk teeth are replaced by molars can be answered ambiguously. After the loss of temporary teeth, a lot of time passes. And if the period exceeds six months, it is better to visit the dental office for examination and identification of problems.

At the age of six, the first indigenous units are just beginning to appear in a child - molars in the amount of 6 pieces for each jaw. The upper ones are distinguished by their large size and high strength, since the root system consists of three roots diverging in different directions.

Due to this feature, they are resistant to loads, reliable fastening. To quickly determine and get an answer to such a question, how to find out a molar or milk tooth, you can count the number.

An adult has 32 strong molars, unlike milk teeth. In the treatment of dairy, it is easy to manipulate by the dentist. With useful information, parents can provide their children with a healthy, beautiful smile.

The need for x-rays

If there are certain difficulties, and parents do not know how to understand a milk or molar tooth, an x-ray can be taken. With its help, you can quickly determine the type of dental unit in the oral cavity.

When the size or shape of the roots differ greatly, then it can be assumed that there is a permanent rudiment in the root. The physiological change of the tooth may be delayed, and therefore you should know how to cope, determine the causes of the delay, the condition of the roots.

In the absence of a permanent germ, it is important to preserve the milk tooth and control the condition of its root. With rapid resorption, it is recommended to prepare for prosthetics.

Panoramic X-ray in Pediatric Dentistry

But when a molar tooth is found on an x-ray and the milk tooth does not fall out, it is advisable to consult an orthodontist for advice.

Based on the image, the specialist will determine the thickness of the bone, the angle of inclination in relation to closely spaced teeth. With the correct location of the root and the removal of the milk, you can count on self-eruption.

Complications of the shift process

The main, important function of permanent dental units in the human mouth is to crush food, and therefore their appearance should be treated carefully. It is necessary to constantly perform hygiene procedures, which will preserve their basic functions and integrity. Otherwise, the intervention of dentists and other doctors will be regularly required.

Self-prolapse of milk units can occur in many children painlessly. But profuse hemorrhages in places of prolapse are not excluded. In situations where the milk tooth fell out a long time ago, and the root does not appear in its place, the help of doctors will be required.

It is likely that treatment will be required, as inflammation or complications may occur. Incorrect growth is also considered a nuisance, which is further reflected in the wrong bite.

Tooth development and eruption

But it is worth considering such a factor as a change in bite is considered a natural phenomenon, and if there are no pathologies, unpleasant symptoms, you don’t have to worry. But with an increase in temperature, the appearance of irritability in a child in the process of changing the bite, you should contact the dentist for help and solve the problems that have arisen without delay.

Proper care for normal development

The eruption of the first permanent teeth requires special care from parents. Initially, the enamel of the root unit does not have sufficient mineralization, which can provoke the development of caries. During this period, it is important to brush your teeth with a toothpaste that contains fluoride. It is desirable that the child take care of the oral cavity after each meal, rinse with clean water.

Be sure to visit the dentist at this time for a consultation, examination of the correct development. In this period, there is an increase in the sensitivity of the enamel, which will require eating foods high in calcium. The child needs to receive a vitamin and mineral complex, which will be prescribed by the doctor at the appointment.

If your teeth grow crooked or incorrectly, you may need the help of an orthodontist. But you should also pay attention to the bad habits of the child, like sucking the tongue, fingers, other objects and try to eliminate them.

With a noticeable staggering of the tooth, it is necessary to wait for its natural loss, which will be less painful for the child than pulling out in the dentist's office. If inflammation is noted, then the help of specialists is urgently required.

In conclusion, it should be noted that the problems that arise with the process of changing teeth can be eliminated both independently and by contacting a doctor. Their final formation occurs in humans by the age of 17.

It is advisable to control the process of loss and exclude solid food from the child's diet at this time. The mouth can only be rinsed with saline to prevent pain and infection in fresh wounds.

An even bite has a significant impact on human health. No wonder every mother is interested in the appearance and change of bite in her child. Questions often arise when determining the type of tooth in the mouth of a child - whether it is milk or indigenous.

Ask an expert

I think that you can still save a lot on visits to the dentist. Of course I'm talking about dental care. After all, if you carefully look after them, then the treatment really may not reach the point - it will not be required. Microcracks and small caries on the teeth can be removed with ordinary paste. How? The so-called filling paste. For myself, I single out Denta Seal. Try it too.

Change of bite is accompanied by complications and it is necessary to understand their nature.

How many teeth should a child have

Most parents do not track the growth of their child's teeth. If the process is painless. Moms and dads start from the fact that milk teeth will fall out in due time, this is a false statement. The process of bite replacement needs to be traced.

Complete eruption of milk teeth suggests completion in children at 2.5 years. By this age, the crumbs grow 20 dental units, including:

8 incisors;
4 fangs;
8 molars.

There is a possibility that the baby did not erupt more than 20 milk teeth. If there are more dental units, they have the shape of an awl, grow to the side. The lack of teeth is caused by the destruction of their rudiments during the development of the fetus.

Tooth classification

People by definition of molars mean permanent teeth. Although this concept belongs to different categories. The following types are divided:

Incisors - are teeth in front of the lower and upper jaws. They have a sharp edge, are involved in biting off food pieces.
Fangs - have a thickened shape, allow you to tear dense food.
Small molars (premolars) - located fourth and fifth in the dentition.
Large molars (molars) - located farthest - 5.6, 8-ki. Large teeth with a large chewing surface, like premolars, are designed to grind pieces of food.

Such species are capable of being dairy, but only the first and second molars erupt from chewing babies. Troubles are formed directly with molars when determining whether it is root or temporary.

When does tooth replacement take place?

Replacing milk teeth with permanent ones is considered an important step. Usually the latter erupt after the loss of temporary ones.

The timing of the appearance may shift according to the anatomical and physiological characteristics of each baby, climatic living conditions, daily diet.

The classic change of bite involves the sequence:

primary molars appear in babies 5-6 years old;
then the main incisors of the lower jaw are replaced;
at the same time, upper and lateral incisors appear on the lower jaw;
eight-nine years of age is accompanied by a change in the upper lateral incisors;
up to 12 years there is a change of small molars;
at the age of 13, fangs change;
about 14 years old, a second pair of molars appears, which are absent among dairy ones;
after 15 years, teenagers begin to erupt third molars, called "wise" teeth. At times, they can remain in the gums until old age.

According to medical research, first the teeth of the lower jaw fall out, then the upper. Milk teeth change in a sequence similar to the appearance.

How to distinguish a permanent molar from a milk tooth?

The change of bite is carried out over time and ends by about 14 years. The rule does not include third molars, extreme in the dentition, referred to as "wisdom teeth". They appear at a more adult age of 17-21 years and older.

There are cases when dental units remain under the gingival surface, not appearing on top of it. With an active change in bite, it is difficult for parents to remember which of the 20 primary teeth has been replaced and which has not.

Distinguishing features will help to accurately determine the type of molar:

The shade of enamel in milk molars is white, in root molars it is light yellow.
The number of dental units - milk 20, permanent - 32.
Volume and shape. Temporary molars are small and round in shape, permanent molars are voluminous.
Location - the eruption of milk teeth is carried out vertically, the permanent crowns are directed outward to the lips and buccal surface.
Child's age. The first dental units appear in 6-7-month-old babies, permanent ones - at the age of 5-6 years.
If the molar is the 6th or 7th, then it is the root, the number of milk teeth on each side of the jaw can be only 5.
The milk molar, in contact with the gum, forms a thickening.
Milk teeth are represented by incisors, canines, molars, permanent ones additionally include premolars.
Dairy roots are thin.
The tubercles located on the milk teeth are smooth, on the molars they are serrated.

Do you get nervous before visiting the dentist?

YesNot

When the type of tooth is not visually determined, an X-ray of the jaw should be taken. A permanent maxillary molar will have a triple root extending into the periosteum.

Prevention of misalignment

The formation of milk teeth, their replacement is a natural phenomenon. Despite this, diseases or dietary problems can affect teething and provoke dental problems.

The following factors affect the change of bite:

genetics. Hereditary predisposition affects the rate of formation of new ones, their shade, strength, bite;
diet - the type of food consumed, balance, the presence in the daily menu of the required amount of protein, minerals, fiber, which affect the shift processes;
the general well-being of the child, both physical and psychological. Diseases, excessive physical activity, emotional stress can slow down the eruption;
non-compliance with the rules of oral hygiene. The development of carious microorganisms causes dental pathologies that can lead to the removal of milk teeth. They hold a place for permanents, with early removal, the eruption of permanents is difficult.

In order for the child’s smile to be snow-white even when growing up, teach him to carry out hygiene procedures.

Possible pathologies of teeth in children

Among the diseases in two-three-year-old babies, caries develops. The destruction of dental units at an early age can cause complications, impaired jaw development, displacement of permanent molars. There may be an infection in the rudiments of molars.

Replaced dental units are able to grow crookedly if the milk ones were straight. This is due to the slow growth of the jaw. Due to the lack of space, the teeth begin to squint, protrude, grow from above.

Possible threat of "shark teeth". This happens when the roots began to erupt before the loss of milk. The situation with teeth that grow in the back row becomes serious. Then resort to the help of an orthodontist. There are cases when it is time to change teeth, but they do not appear. This may be due to physiological reasons, genetic, adentia.f

The process of formation of the dentition in humans goes through two main stages. The first is the eruption of milk teeth, and the second is their change to permanent ones (for more details, see the article:). Usually, both periods are associated with many accompanying unpleasant symptoms. In addition to painful sensations, cutting teeth can cause poor sleep and appetite, moodiness, fever, and in some cases even vomiting and diarrhea. Parents should have information about the timing, symptoms, rules for caring for the oral cavity at these stages and all the nuances of eruption and change of dental units in order to alleviate the child's condition.

How many teeth should a child have?

It is a well-known fact that an adult smile consists of 32 teeth. However, how many of them are there in children? By the end of the process of eruption of all milk teeth, which ends approximately at the age of 2 to 2.5 years, the child should have 20 dental units, which include:

eight incisors, four in the lower and upper row;
four fangs;
eight molars.

There is a standard scheme for the eruption of milk teeth in children, which shows the average timing and sequence of their appearance (see also:). It is presented in the table below:

However, there are cases when the process of the appearance of teeth in a child is disturbed:

It is possible that the child will not have 20 milk teeth, but more or less. In the first case, the extra ones look like an awl and grow to the side. In the second, the lack of dental units is due to the death of their rudiments during the period of gestation.

The structure and features of eruption of milk teeth

This article talks about typical ways to solve your questions, but each case is unique! If you want to know from me how to solve exactly your problem - ask your question. It's fast and free!

The first temporary human teeth were called milk teeth by the healer, doctor and philosopher of Ancient Greece Hippocrates, known in history as the father of medicine. In his opinion, their development is due to breast milk, which children receive at the beginning of their lives, since it is rich in calcium, which is necessary for the growth of bone tissue.

Milk teeth and their roots have their own differences and structural features. In many ways, their condition is associated with the full nutrition of the child.

Resembling permanent root units in structure and shape, they do not have the same strength, and their enamel is much thinner. They are also characterized by:

small crown size;
slightly divergent roots, between which the rudiments of future permanent teeth are located;
large volume of pulp;
large width of root canals.

As for the roots and nerves, contrary to the myth of their absence, milk teeth have the same number of them as molars (we recommend reading:). During the period of eruption of the first teeth, the roots also grow, stopping growth at the end of this process. Further, when the milk teeth are replaced by permanent ones, the roots are resorbed.

In general, the development of dairy, or interchangeable, teeth is divided into 5 stages:

The sequence of change of dentitions in a child

The second important stage is the change of dairy units to permanent. In most cases, the latter appear after temporary. Below is a standard diagram of how teeth change, with time intervals and the sequence of loss:

According to statistics, the lower teeth usually fall first, and behind them - the upper ones. According to the scheme, the change of milk teeth occurs in the same sequence as their appearance.

Differences of constant root teeth and milk

Despite the fact that temporary and permanent teeth have the same structure, there are a number of signs that will help you understand how to distinguish a milk tooth from a permanent one. You can determine which tooth is present in the oral cavity by:

Temporary and permanent teeth also differ in what numbers are used to designate them in the dental formula (see also:). In dairy, these are Roman numerals, for example, I and II are incisors, III are canines, IV and V are molars, and in indigenous ones they are Arabic: 1 and 2 are incisors, 3 are canines, 4 and 5 are premolars, 6.7 and 8 - molars. There are people who do not have figure eights, better known as wisdom teeth.

Is it possible to understand by external signs whether a permanent tooth or a milk one?

To find out which class a tooth belongs to, you do not need to be an experienced dentist and know everything about the structure of the jaw and how the root system and the periodontium itself look like. To distinguish a milk tooth from a molar one will help external signs that are visible even in the photo. They include:

The size. First, milk teeth are smaller than permanent teeth in general. Secondly, the permanent ones are more elongated, that is, they are smaller in width than the temporary ones.
Form. The tubercles that are present on the milk teeth are smooth, on the molars they are serrated, called mamelons.
Enamel color. As mentioned earlier, the thin and rich enamel of milk teeth is distinguished by its whiteness, while in the molars it is characterized by a yellowish color.

Possible pathologies of teeth in children

The teeth of children are still fragile and therefore more prone to various dental diseases, the neglect of which can become a serious complication in the future. This also applies to milk teeth, despite the fact that they have to change.

The most common dental disease in babies is caries, which can be diagnosed as early as 2-3 years. If the teeth begin to decay at such an early age, it can lead to serious complications such as jaw pathologies and displacement of the molars. In addition, the rudiments of permanent teeth can also be infected.

Teeth after a change can grow crooked, even if the milk teeth were even. Most often, the reason lies in the slow growth of the jaw itself. As a result, the teeth do not have enough space, and they begin to bulge, distort and grow above the others. The habit of thumb sucking or other objects may also contribute to this.

There is also a risk of growth of so-called shark teeth. This phenomenon is observed when the constants have already begun to erupt, and the milk ones in their place have not yet fallen out. The situation is considered especially serious if there are not one, but several such teeth growing in the back row. In this case, you can not do without the help of an orthodontist.

It happens and vice versa - the time has come to replace the teeth with permanent ones, but they do not grow. This is due either to a physiological delay associated with heredity, or adentia - the absence of the rudiments of molars.

During the period of mixed dentition, both milk (temporary) teeth and molars (permanent) teeth are in the child's oral cavity.

Sometimes even the most attentive mother, who carefully monitors the change of teeth, does not know how to distinguish a milk tooth from a permanent one. Going to the doctor for most children is very stressful and can turn into a tantrum. Therefore, to begin with, we will try to determine how to do it at home on our own.

How to find out a milk tooth or root at home?

The first criterion by which teeth can be distinguished is the age of the child.

Milk teeth appear in a baby from six months and usually grow in the amount of 20 pieces by 2 years.

Permanent ones begin to appear in a child from 5-7 years old. A complete change occurs mainly by the age of 14.

Therefore, if the task is to check what kind of teeth a three-year-old baby has, then the question disappears by itself - definitely milk teeth.

But, the time frame for tooth growth is very conditional. There are cases when, for example, they begin to erupt not at six months, but at three (or vice versa).

All people are different, the body works according to the schedule, but its own, and not averaged by doctors.

The second criterion is appearance.

Color. In temporary teeth, it is more snow-white than in molars. They, in turn, are more yellow due to the increased amount of mineralized tissues.
The form. The permanent ones are more angular than the dairy ones.
The size. Indigenous are larger than temporary ones.
growth angle. Milk teeth usually grow strictly vertically, molars - with a slight outward inclination.
Height. Temporary shorter than permanent.

The scheme of loss of milk teeth in children

The first and second are incisors. Milk incisors are more rounded and smaller, the wavy contour is quickly erased. The molars are characterized by a wide crown, mamelons (tubercles on the teeth) over time may be mild, but still present.
Third - fangs. Due to the greater vulnerability, the milk fang wears out over time and does not look as sharp as we are used to seeing it. The root canine remains sharp for life.
The fourth and fifth are molars. The crown of the temporary teeth of these rows is wider than that of the molars. Also, such milk units have four tubercles, while indigenous ones have two.
Sixth. As already mentioned, . Therefore, five units are occupied in the jaw arch. If another one appeared in the sixth place, it is definitely indigenous, there can be no dairy in that place.
Seventh - wisdom teeth. They, like the sixth ones, appear only on a permanent basis, usually at the age of about 20 years and older, or do not appear at all.

There is one easy way to understand what a certain tooth is - to compare it with the same one on the other side.

How to tell by x-ray?

If the tips from the previous section did not help, you need to contact your dentist. He has two ways to distinguish a molar from a milk tooth:

Dental manipulations. If a tooth that is in doubt needs to be treated, then the doctor will quickly understand whether it is temporary or not. Dairy ones differ from permanent ones in thinner enamel, therefore, in softness, so a professional doctor will quickly determine which tooth is in front of him by texture.
X-ray. The need for it arises in specific situations. For example, when the change of teeth is late and parents are already doubting which tooth is “in business” now. According to the picture, the doctor analyzes the nature of the roots. In dairy they are thin, in indigenous ones they are large.

Panoramic X-ray - Interchangeable Bite

No need to do an X-ray of a child out of idle curiosity. This study should take place according to the testimony of a doctor.

How to determine that a child will soon grow permanent teeth?

Temporary teeth are needed for a period of active growth. That is why there are only 20 of them, and not 32 as in the end.

Because more in the children's jaw simply does not fit.

All milk teeth completely fill both jaw arches and stand tightly, without gaps. Further, the child grows up, along with him and the head and jaw.

Changes appear: gaps form between the teeth, the crowns themselves begin to gradually wear out, and their roots slowly dissolve. And when a milk tooth can no longer hold in the gum due to a short root, it falls out. If one of the milk ones fell out, you can expect the appearance of a permanent one in its place. Usually the lower front incisors are the first to lose ground.

Another signal that the child has begun to change the bite is the growth of the molars in the sixth row, which were mentioned earlier. This happens in time at about the same moment when the incisors begin to fall out.

One of their important functions is that they set the direction and place of growth of the permanent tooth that occupies it. Therefore, it is very important that a gradual change of teeth occurs.

If the parents and the child did not follow the temporary teeth well, then they quickly darken and crumble, and then fall out completely.

Which is bad, since under them the root of a permanent tooth has not yet had time to form to the proper extent, which in the future, ideally, would have to “drive” it out of the hole.

There is a myth that there is no need to treat milk teeth, because sooner or later they will fall out anyway.

To dispel it, let's add an explanation:

temporary teeth are needed not only for crushing and chewing food, they also participate in speech formation. The absence of a tooth affects the pronunciation of a particular sound, which entails the occurrence of complexes in the child, as well as problems with socialization;
even without one tooth, it becomes more difficult to cope with food, which can affect the functioning of the gastrointestinal tract;
when a free space arises due to a fallen tooth, the rest begin to fill it, as it is by nature. As a result, the indigenous may grow out of place;
if the milk tooth is affected during the period of maturation of the root under it, then in the absence of treatment, the disease passes to it;
It is worth remembering that permanent teeth appear closer to 11-13 years. If at the age of 5 a child does not have, for example, front incisors, this is not good.

Are all milk teeth in humans replaced by molars?

All milk teeth are replaced with new, more durable, strong and stable ones. :

6-7 years old - central incisors of the lower jaw, upper and lower molars;
7-8 - upper central and lower lateral incisors;
8-9 - upper lateral incisors;
9-10 - lower fangs;
10-12 - the first and second premolars on both jaws;
11-12 - second lower premolars and canines from above;
11-13 - second lower molars;
12-13 - second upper molars;
18-22 – .

As you can see, there is not a single milk tooth that is not involved. But as already mentioned, there are exceptions, they are quite rare and are easily corrected.

Nowadays, the dental industry in medicine is one of the most expensive.

To less often go to the doctor with problems, you need to instill a dental culture in your baby from childhood:

Perform oral hygiene in the morning and evening.
Rinse your mouth with plain water after each meal.
Don't forget to use .
From the age of one year, visit the dentist annually for prevention and more often if treatment requires it.

Temporary and permanent teeth also differ in what numbers are used to designate them in the dental formula. In dairy, these are Roman numerals, for example, I and II are incisors, III are canines, IV and V are molars, and in indigenous ones they are Arabic: 1 and 2 are incisors, 3 are canines, 4 and 5 are premolars, 6.7 and 8 - molars. There are people who do not have figure eights, better known as wisdom teeth.

Milk and molars have many differences. First of all, it is worth noting that milk teeth are temporary, over time they fall out, and teeth take their place. The process takes place with some effort.

Of particular importance are special cells that destroy the roots of milk teeth. As a result, they lose their grip on the jaw. The root becomes thin and long. This form accompanies the extrusion of a milk tooth under the influence of previous factors.

If the tooth itself does not fall out for one reason or another, then it can be easily removed with the help of dental instruments.

You can also distinguish between teeth by number. First of all, it is worth noting that an adult has 32 molars.

Their roots bend and diverge, which provides a secure attachment to the jaw. Milk teeth have a characteristic shape. In the cervical part of the tooth, a pincushion-shaped thickening can be observed.

It is also worth noting that milk teeth are less hard than permanent teeth. They are easily amenable to drilling and other manipulations carried out by the dentist for the purpose of treatment.

With this information, each parent can easily recognize which tooth is growing in a child. In the future, this will allow for careful monitoring of changes in the bite.

How many teeth do 6 year olds have?

eight incisors, four in the lower and upper row;
four fangs;
eight molars.

However, there are cases when the process of the appearance of teeth in a child is disturbed:

According to statistics, the lower teeth usually fall first, and behind them - the upper ones. According to the scheme, the change of milk teeth occurs in the same sequence as their appearance.

Teeth after a change can grow crooked, even if the milk teeth were even. Most often, the reason lies in the slow growth of the jaw itself. As a result, the teeth do not have enough space, and they begin to bulge, distort and grow above the others. The habit of thumb sucking or other objects may also contribute to this.

Waiting for the first milk teeth in a baby is an exciting and pleasant time, although it is accompanied by some inconvenience. However, one expectation is soon replaced by another. And now mom and dad can’t wait until the baby teeth begin to change into permanent ones.

Changes associated with the growth and loss of teeth in a child always raise a lot of questions. One of the first - when the first molars appear. Answer: 6-7 years old. The rest you will learn from our article.

Growth and change of milk teeth

It is interesting to know that milk teeth begin to form when the baby is in the womb. And after birth, permanent teeth begin to develop in the gums. This is a long and exciting process, the duration of which depends on the characteristics of the individual development of a small person.

Normally, an adult has 32 teeth, 16 each above and below. A small child has fewer of them - only 20. The critter begins to lose its milk wealth as soon as the formation of permanent teeth in the gum ends. They erupt, displacing temporary teeth.

Possible pain when changing teeth is a subject of frequent unrest among parents. But we hasten to reassure: in 90% of cases, the eruption of molars occurs almost painlessly. The roots of milk teeth simply dissolve, resulting in natural loss. Most often, the lower teeth change first, but how this will happen in your child and at what speed is an individual question.

On average, all teeth change within 6-8 years. That is, by the age of 14, a teenager will already have a complete set. However, even here there are some nuances. Ultimately, the intensity of the loss of old and the eruption of new teeth is influenced by genetic predisposition, as well as the quality of nutrition. Even drinking water can affect the speed and then the health of your child's teeth.

Under normal conditions, the shift begins at the age of six. Dairy units 20, permanent - 28. 20-25 years - the age of the appearance of the third molars. They do not grow in everyone, but the absence (complete or partial) is not considered a pathology. The order of teething in children reflects the table.

The figures are relevant for both jaws, except for canines and molars: the lower ones change before the upper ones. There are no premolars that erupt for the first time at the age of 10-12 in the milk bite. Shedding occurs as the roots dissolve from the top to the base.

Scheme of changing teeth. Will molars change? The term refers to molars (chewing units) that erupt twice. The name is also used in relation to permanent units that grow once and remain until the end of life.

Most often, the loss of milk teeth begins in a child at the age of six. But in some babies, the first milk tooth can fall out at 7 years old.

This is due to the fact that the process of loss of milk teeth and the growth of molars is individual for each child, as it is associated with a hereditary predisposition. That is, if one of the baby's parents had a change of teeth in childhood earlier or later than 6 years, then it is highly likely that their child will begin to lose milk teeth in the same period.

The baby “loses” milk teeth due to the fact that the molars, starting to grow, destroy their roots. This causes the baby tooth to loosen and fall out. Milk teeth in children of 6 years old fall out in the same sequence in which they grew. The lower central incisors fall out first, followed by the upper central incisors.

When a baby tooth falls out, a small wound forms in its place, which can bleed for 5-10 minutes. To prevent the baby from swallowing blood, it is necessary to make a sterile gauze or cotton swab and let the baby eat it for 15 minutes.

If bleeding from a wound at the site of a lost milk tooth lasts longer than the specified time, then it is necessary to show the child to a pediatrician and / or pediatric dentist. Perhaps the doctor will send the baby to take a blood test for clotting and prescribe medication based on the results of the analysis.

We have already examined how the process of falling out of a milk tooth occurs, now we will consider how teeth grow in children of 6 years old. Most parents believe that the growth of molars in a child begins after the first milk tooth falls out, but this is not so.

Even before the baby's milk teeth begin to loosen, the first molars, which are called the first molars, erupt. These are two pairs of chewing teeth that appear in the free space of the upper and lower jaws of the child.

Now we will analyze how teeth are cut in children, in the event that they grow in place of milk teeth. Between the loss of a milk tooth and the appearance of a root in its place, 3-4 months pass.

All this time, the permanent tooth grows inside the gums. When the root tooth “approaches” the gum, it begins to turn red, as the blood flow to it increases, and swells a little, then the process of teething occurs.

Sometimes it happens that a molar tooth does not appear in the vacant place of the gum for six months, and the child's parents, of course, begin to worry about this. Usually, such long-term tooth growth in the child's gums is an individual feature of the baby, but in order to make sure that everything is in order with the teeth, it is necessary to take the child to the dentist and take an orthopantomogram (X-ray of all teeth of the lower and upper jaw).

The overview x-ray will show how teeth are cut in children of 6 years old, since it shows those teeth that have already erupted and those that are still in the gum.

In some cases, milk teeth do not allow the molars to erupt: the permanent tooth is already ready to appear, and the milk one “does not want to” fall out. This can lead to the development of an inflammatory process in the child's oral cavity, the appearance of pain, naturally, because of this, the baby will become capricious, his sleep will be disturbed.

Therefore, in such situations, the child must be immediately taken to an appointment with a pediatric dentist. The doctor, under local or general anesthesia, will remove the baby's baby tooth, perhaps prescribe an antiseptic mouth rinse to stop the inflammatory process.

How many teeth do 6 year olds have? - this is an interesting question, since at this age the number of teeth in a child can vary from 20 to 24. Let's consider why this is so.

By the sixth year of life, the baby has 20 milk teeth in his mouth, which "settled" there when the child was 2.5-3 years old. At the age of six, a pair of first permanent chewing teeth begins to erupt in a child in the lower jaw, and then a pair of upper ones.

In total, the baby has 24 teeth in his mouth: 20 of them are milk and 4 are molars. Then the process of loss of milk teeth begins, and, as a result, the child's teeth become smaller.

At the age of six, the baby usually “loses” 4 teeth: a pair of upper and lower central incisors. That is, a child’s teeth can again become 20.

Also, at the age of 6, a pair of molars of the lower central incisors erupt in children, and as a result, 22 teeth are in the baby’s mouth: 16 of them are milk and 6 are molars. There are cases when a pair of primary upper central incisors erupt in a child at this age, and then a baby at 6 years old has 24 teeth.

The above calculations of how many teeth a six-year-old child has are relative, since it has already been said that each baby's teeth fall out and erupt according to an individual schedule. But, based on the generally accepted terms for the appearance of permanent teeth and loss of milk teeth, such mathematical calculations can be made.

The ongoing change of milk teeth to permanent ones imposes certain responsibilities on parents. Naturally, it all depends on the age of the child: at 11 years old, he is more independent than at 5-6.

Regarding oral hygiene, it is necessary to adhere to the following recommendations:

Brush your teeth at least twice a day and, if possible, after every meal.
After eating, rinse your mouth with water, herbal decoction or a special rinse.
Get checked out by a dentist as needed. In order not to miss the “moment”, parents should keep track of how the teeth grow and what their condition is. In the presence of caries, as well as improper growth of permanent teeth, a visit to the doctor is mandatory.
Carry out a fissure sealing procedure. Dentists recommend it as a prevention of caries. During the procedure, the doctor fills the natural cavities between the tubercles of the teeth with a sealant so that food debris does not get there.

Usually, tooth loss is accompanied by mild bleeding, which disappears in 3-5 minutes. If the bleeding does not stop, you should see a doctor for clotting problems.

A well-composed diet of a child is a guarantee of his health and well-being, not only in childhood, but also in adulthood. Of paramount importance is the correct preparation of the menu during the period of changing teeth to permanent ones. What can a child eat, and what foods should be limited?

strong teeth need calcium, so you should feed your baby with dairy products. If the child does not like such food or suffers from its intolerance, you can give him multivitamin complexes containing calcium;
for calcium to be well absorbed, the body needs vitamin D. It is found in fish, liver, butter, eggs, milk and sour cream;
phosphorus is involved in the formation of bone tissue. Especially a lot of it in cheese and seafood;
to stimulate the resorption of the roots of milk teeth, you should give the child more solid food. Fresh fruits and vegetables are best for this purpose;
it is important to preserve the delicate enamel of newly grown teeth, if possible, excluding various “harmful things” from the menu. Sweets, cakes, cakes, carbonated drinks are highly undesirable during the period of changing teeth.

There is nothing cuter than a child with a toothless smile, even if he himself has a different opinion. But everything passes, and after a couple of years, parents face more serious questions related to the growing up of their child.

healthy-teeth.su

By the age of 2.5 - 3 years, a complete set of milk teeth is formed, an occlusion of temporary teeth is formed. By the age of 3, a child should have 20 milk teeth in their mouth. New milk teeth in the oral cavity will no longer erupt. At the age of 5, permanent teeth begin to erupt. The permanent incisors and molars erupt first.

Since permanent teeth are called molars, which erupt in children to replace milk teeth, they should not normally fall out. They remain with the children until the end of life.

Is it possible to understand by external signs whether a permanent tooth or a milk one?

The size. First, milk teeth are smaller than permanent teeth in general. Secondly, the permanent ones are more elongated, that is, they are smaller in width than the temporary ones.
Form. The tubercles that are present on the milk teeth are smooth, on the molars they are serrated, called mamelons.
Enamel color. As mentioned earlier, the thin and rich enamel of milk teeth is distinguished by its whiteness, while in the molars it is characterized by a yellowish color.

Permanent. Symptoms and the procedure for teething

Absolutely all parents know that milk teeth will appear first in a child, which will then fall out so that permanent ones can grow in their place. However, unfortunately, in many cases, this knowledge is limited.

General information about development

Milk teeth can also be called replaceable or dropping. In their development, they pass five periods next to each other.

Most permanent teeth begin to erupt when the corresponding replacement teeth fall out. You should know at what age this will happen.

Pattern and drop time

The first incisors usually fall out in the center, first of the lower, and then also of the upper jaw from about 5 to 7 years.
Then there are side cutters, on average up to 8 years.
At 9–11, the first molars fall in a similar scheme.
In 10-12 years - fangs, and first more often from below.
Around the same period, the second molars fall out.

From this brief scheme, we can conclude that the order of loss of milk teeth is similar to their eruption.

How is a constant bite formed?

The process of loosening and resorption of the roots occurs under the influence of the growth of permanent teeth from previously formed rudiments.

But the growth scheme here is somewhat more complicated. It should also be noted that in a constant bite, instead of 20 units, there will be 32.

The lower incisors in the center appear at 6–8 years of age.
Almost simultaneously with this, about 6–7 years, the lower and upper molars are replaced.
At the age of 7-8 years, the upper incisors grow in the center.
Behind them at the same time go the side of the lower ones, and at 8–9 - the upper ones.
The first permanent fangs grow from below between 9 and 11 years of age.
A little later, from 10 to 11 years old, the first premolars appear from above, standing in a row after the canine, and up to 12 - from below.
According to the same scheme, the second premolars grow, respectively, the upper ones from 10, and the lower ones from 11 to 12 years.
Only after this, the upper fangs appear in the child - about 11-12 years.
The penultimate ones take their place in the lower (from 11 to 13 years old), and behind them the upper second molars (at 12–13).

The latest in the scheme should be entered the third molars, which are called "eights" or "wisdom teeth".

However, their growth occurs at a later period. If the upper ones are from 16 to 21–24 years old, then the upper ones can become active only by the age of 27–30 years.

It depends on the location, shape and size of the crown part, lack of space on the jaw and much more.

Between the loss of one and the appearance of the second tooth, a rather long time can pass - from several months to six months. This is the norm, so neither small patients nor their parents should worry that the expected growth is still not there.

growth symptoms

The growth of molars or permanent teeth in children in most cases does not cause such pronounced manifestations as in the case of removable ones. This is easily explained by the fact that there is no need to re-push the gum tissue, that is, the path is much easier.

Of course, some unusual sensations are present at this time. Most often, there is itching in the gums, redness, as well as a slight increase in temperature.

If the gums itch very much and even begin to hurt and become inflamed, you can use special means - gels that act as a local anesthetic. They reduce itching and almost completely relieve discomfort.

In addition, the child may experience serious discomfort during the preliminary loss of the first teeth. For the most part, this discomfort is psychological: the usual tooth begins to stagger, it is unpleasant and scary. Children expect pain, heavy bleeding and other things.

It should be explained that there is no need to be afraid that a stronger new one will soon appear instead of this tooth. Often, to calm the baby, parents use a fairy tale about the Tooth Fairy, who takes the fallen replacement, for which she brings a gift.
