Types of dental fillings and their differences. General requirements for dental fillings

In dentistry, a filling is a certain material that fills a cavity in an affected tooth in order to isolate its sensitive tissues and protect it from microbes. Today, there are different types of fillings for teeth, each of which has certain properties, characteristics and purpose.

What are dental fillings?

The main difference between all types of fillings is the material from which they are made.

Cement

A cement filling consists of a powder and a liquid, which, under the influence of a chemical reaction, are converted into a rapidly thickening mass.

The main disadvantage of this type is too fast hardening, which limits the time for installing a filling and creating a dental relief.

In addition, such a filling becomes as strong as possible only after 2 hours, during which food intake is unacceptable.

At the same time, cement fillings are the most affordable.

plastic

This type of filling was very popular and often used due to its quick installation and low cost. The main material is plastic plastic, which is introduced into the tooth cavity and hardens. Over time, it was found that plastic is toxic, wears off very quickly, changes color, does not tolerate mechanical stress and can cause allergic reactions. This was the reason for the termination of its use.

Amalgams or metal

These materials consist of a solution of metals, silver and mercury. They can be silver, copper and gold. Seals from them are very strong, hard and most resistant to mechanical stress and the influence of saliva.

But there are also disadvantages that have led to the extremely rare use of amalgams:

• ugly appearance (absolutely unsuitable for fillings on the front teeth);
• very slow hardening;
• decrease in volume over time (shrinkage);
• high probability around the filling (a few years after installation);
• partial staining of the tooth with metals that are part of the alloy;
• the occurrence, burning, taste of metal, requiring replacement of the seal.

In addition, the installation of such fillings today is complicated by the lack of equipment specially designed for this purpose in the configuration of dental offices.

Composite

The durability and strength of fillings is influenced not only by the quality of the materials and the professionalism of the doctor, but also by some individual structural features and, the quality of nutrition, the presence of bad habits in the patient.

Types of dental fillings and their cost

The cost of different ones depends on the degree of damage and structural features of the tooth, the manufacturer of the material and the clinic in which the installation is carried out.

On average, their cost is:

• about 500 rubles - cement;
• about 1000-1500 rubles - glass ionomers;
• about 1500 rubles - metal (in state clinics - free of charge);
• about 2000-4500 rubles - light-hardening;
• about 2700 - composite.

Filling is the process of restoring a tooth, taking into account the anatomical features. In the modern world, technology allows you to take into account the color, structure and transparency of the surface.

For this procedure in dentistry, specialized filling or restorative materials are used. They are divided into several types and subspecies, which must meet certain requirements in accordance with their purpose.

Classification of filling materials

Materials for root canals are divided into several areas.

Depending on the group of the tooth:

1. For anterior teeth. Must meet cosmetic requirements.
2. For chewing teeth. They have increased strength and withstand heavy loads.

According to the material used in the manufacture of restoration fillings are:

• from metals: amalgams, pure metal, alloys;
• : composite, cement, plastic.

Depending on the purpose, filling materials are divided into:

• for overlay and dressings;
• for permanent fillings in diagnostics;
• laying if necessary treatment;
• insulating gasket;
• to close the root canal.

The materials used in the manufacture of seals are also divided according to their purpose.

For the following cements are used:

For insulating pads:

• zinc phosphate cements;
• glass ionomer cements;
• polycarboxylate cements;
• varnishes;
• dentine bond systems.

For medical pads:

• preparations based on calcium hydroxide;
• zinc-eugenol cement;
• materials containing medicinal additives.

What characteristics should dental materials meet?

Requirements for filling materials were developed and approved at the end of the last century by Dr. Miller. In modern dentistry, they almost did not change, minor additions and clarifications were made.

Restorative dental material must comply with the following technological and aesthetic standards:

Modern technologies have made it possible to come close to meeting these requirements, but still there is no ideal material at the moment.

For this reason, cases of combining restorative mixtures are quite frequent in dentistry. Up to 4 different layers can be used, depending on the characteristics of the tooth itself and tissues, location, characteristics of the disease.

In addition, the nature of work with types of materials differs in the tools used and the technical process.

The use and technique of working with various filling compositions depends on the area of ​​​​its application. Consider the most commonly used materials.

Phosphate and zinc phosphate cement

It has a wide range of applications: from permanent fillings with subsequent isolation to use as an insulating gasket when filling with other materials.

Sealing technique

Prepare powder and water. After that, they move on to the oral cavity. The tooth is isolated from saliva with cotton swabs and the cavity is dried with a stream of air.

Phosphate cement is mixed with a chrome or nickel-plated spatula. The consistency is considered ideal if the mass does not stretch, but breaks, leaving teeth no higher than 1 mm. The resulting composition is introduced into the tooth cavity in small portions, carefully filling the entire space.

It must be taken into account that filling and modeling must be completed before the material hardens. When removing the excess with a trowel, the movements should go from the center of the filling to its edges with great care.

When installing an insulating gasket, the mixture is applied over the entire surface of the cavity, including the walls, but does not reach the edge of the enamel, since this type of material is quickly absorbed and can cause corrosion of the cavity around the filling.

Zinc Phosphate Cement I-PAC

Due to the fact that its composition does not provide sufficient adhesion, and also has a pathogenic effect on the pulp, this operation is carried out only with a phosphate cement gasket installed.

When making an insulating layer, the mixture may be less thick than when filling, but not reach a creamy consistency.

After the phosphate cement has dried, they proceed to the application of the base material.

Sealing process

Silicate cement is also mixed with water until a homogeneous thick mass is formed and introduced into the cavity. It should be borne in mind that when working with this material, it is necessary to fill the space in 1, maximum 2 steps.

Since the partial filling of the cavity violates the solidity of the seal. It is necessary to model the shape and remove the excess before the material dries, since in the solid state it is difficult to eliminate deficiencies.

The final filling procedure is to cover the filling with wax, petroleum jelly or varnish.

Silicophosphate materials are also used. Due to the use of two materials, no additional insulating pad is required in this case. Mixing and filling proceed in the same way as for phosphate cement.

Polymer materials

Given that this group is aesthetically practical, it is used mainly on the front teeth. The process starts with

Filling material Vitremer

preparation of the oral cavity, isolation of the tooth and drying.

When using a polymer, a phosphate spacer is also required. Only after its application, they begin to manufacture a mixture of noracryl powder and monomer liquid.

A cellophane film is placed on the glass surface, the desired color of the plastic is selected. The powder is applied to the surface and thoroughly mixed with the liquid, the mass is rubbed over the cellophane with wide strokes of a spatula. The filling procedure is recommended to be carried out in two stages.

Immediately after kneading, when the consistency of the composite is rather liquid, the first part of the mass is added, thereby displacing air from the cavity and filling in the irregularities. After that, make the second part until full filling.

Modeling of the form occurs at the initial stage of solidification of the material with the help of a trowel. Do not rush to eliminate the excess in the elastic state of the composite, so you can break the edge adhesion.

This material completely hardens within a day. At the next visit, the patient is given the final revision of the filling. In this case, the surfaces of the grinding material must be moistened with water and used at low speeds to avoid heating the seal.

Uses of Acrylic Oxide

This material has increased resistance to physical and chemical irritants, high adhesion to surfaces and does not lose color for a long time.

An insulating gasket is applied only in cases. After selecting the desired shade, acrylic oxide powder is poured into the crucible.

Cement is kneaded according to general requirements, if necessary, gaskets. Next, liquid is added to the crucible and stirred for about 50 seconds. A mass of solution is applied to the prepared cavity in one go.

The hardening of the material begins after 1.5 - 2 minutes, during this time it is necessary to model the filling. Full curing time takes 8 to 10 minutes. After that, the final stage of machining takes place.

Composite material consize

Recently, the recently developed new composite filling material consize has become popular. It has high aesthetics, good adhesion to fabrics and other materials.

But given that with such a filling, the tooth enamel is treated with acid, it is imperative to apply an insulating gasket. The advantage of using this material is the absence of pre-preparation.

Installation Method

The surface is thoroughly cleaned by mechanical processing. Etching liquid is applied for 1.5-2 minutes, after which the tooth washed with clean water and dried thoroughly.

After this process, it is necessary to ensure that the tooth is isolated from saliva. The etched area will acquire a pretty shade. Then two equal parts of the liquid filling material are mixed with a swab and applied to the area.

After that, two parts of the previously prepared paste are mixed and the cavity is filled. When modeling, a trowel is used, and in case of significant defects, a cellophane cap is used.

Surpluses should be eliminated before consizing solidifies. The hardening of the seal takes up to 8 minutes, after which you can start machining. All materials, including paper napkin and foam swabs, are included.

The article discusses modern filling materials most commonly used in dentistry. Before starting work, it is necessary to carefully determine the degree of the patient's disease and the defect of the teeth.

Filling material Estelight

Since manufacturers use components with different consistency in the manufacture of materials, it is necessary to read the instructions before starting filling. The time of solidification, thickening of the mixture may vary slightly. But at the slightest deviation from the required conditions, the seal may lose the required properties.

The dentist places a permanent filling in the cavity of the tooth left after the removal of caries. It is needed in order to cover the sensitive tissues of the tooth and prevent saliva and food debris, as well as bacteria and microbes from getting inside. In addition, with its help, the dentist-therapist restores that part of the tooth that had to be removed during treatment. This is necessary not only from an aesthetic point of view, but also because an incomplete tooth will not be able to fully participate in the closing of the jaws, and this can lead to malocclusion. Therefore, it is so important for the doctor to properly grind and polish the seal, because the average life of its service is about five years.

Temporary filling, as its name implies, is carried out for a short period of time, usually no more than two weeks. It is also needed when the tooth treatment takes place in several stages, which means several visits. This happens when medicine needs to be placed in the root canals for several days, or when the treatment is so long that the patient cannot sit in the chair for so long at a time, or when the dentist is going to install a ceramic tooth instead of a permanent filling. an inlay, and its manufacture takes place in a dental laboratory according to casts from a treated tooth and takes from one to several days. In such cases, a temporary filling helps, it is cheaper than a permanent one, it is installed faster and is easily removed when it is no longer needed. But at the same time, it also protects the drilled cavity from saliva, food debris and bacteria.

What are permanent dental fillings?

Permanent fillings differ in the material from which they are made. Most of the materials that were previously used by dentists to place a filling are no longer used today. These are various metal alloys that have become a thing of the past due to their high thermal conductivity (they could cause pulp overheating), dentistry has abandoned most plastics due to their toxicity and fragility, many types of cements are not used due to their inability to imitate color and density. a natural tooth, and also due to the fact that they required a thorough turning of healthy tissues.

Modern dental fillings are made from composite materials. And here they are represented by two main varieties - these are chemical and light fillings. The former is named so because it requires a chemical reaction to harden, while the latter is cured by a special blue light produced by a dental lamp.

Light-curing filling: advantages and features of installation

A more accurate name for this dental composite material is a photopolymer filling. The prefix "photo-" indicates that a special light is needed to cure the filling, and polymers are composite materials.

A light filling gives the dentist the opportunity to accurately reproduce a full-fledged tooth, because, unlike a cement filling, it only hardens under the influence of a lamp. However, it is worth remembering that over time, even the best light-cured filling will darken or become noticeable at the border with the enamel. Therefore, and also because it may fall out at the end of its service life, the design requires timely replacement, on average, once every five years. As for the installation of fillings on the front teeth, modern dentistry suggests using ceramic inlays instead. They are better, imitate natural tissues, last longer and are practically invisible on the teeth even after a few years.

How much does a filling cost?

Before answering this question, you need to understand what is included in the price. Before placing a filling, the doctor needs to remove the tissue damaged by caries, fill it with filling material, grind and grind the restored tooth. In most cases, the cost of a filling is included in the price of caries treatment, which averages from 1,000 to 3,000 rubles in economy class clinics (although in some price lists you can find prices starting from 500 rubles), it will cost from 4,000 rubles treatment of caries and installation of a light filling in business class dentistry and from 6,000 rubles in premium clinics and VIP dentistry in Moscow.

What are the complications after a filling?

The most common complaint of patients after visiting the dentist is the feeling that the tooth hurts under the filling. Such sensations are absolutely normal for several hours after treatment (up to 1 day), but if the pain does not subside the next day, this may mean that the doctor made a mistake, for example, he poorly processed the carious cavity before installing the filling. If a day has passed, and the tooth still hurts, you need to go to the dentist again, you may have to take an x-ray and, if necessary, re-treat.

Another common reason for visiting a dentist is when a filling has fallen out. As we have already said, these structures have a certain service life, after which they need to be changed, if this is not done, they can really fall out. And in such situations, the main thing is to understand why this happened - because the tooth has not been treated for a long time, or has secondary caries developed in it? As for fresh fillings, they can fall out only in case of a medical error. Therefore, choose proven clinics where quality fillings are installed in Moscow.

What kind of care do fillings need?

Filled teeth do not require any special care, but we must not forget that it is necessary to clean them, regardless of whether they have fillings or not, at least twice a day and very carefully. Also, dentists recommend visiting the procedure of professional oral hygiene at least once every six months. At the same time, the hygienist should grind the existing fillings and pay special attention to them.

You also need to remember that the filling material is still more porous than enamel, so it absorbs pigments from coloring foods and drinks more strongly. That is why immediately after the treatment of caries it is not recommended to eat beets, red berries and similar foods for several days, especially when it comes to the front teeth.

Fillings are the most common dental service. The technique is actively developing, which is why every year appearnew types of dental fillings. Today, the most modern technologies and materials are used in this area of ​​dentistry. Some of them deserve special attention.

What is a dental filling

This term usually means medical material that fills the voids in the tooth. The seal protects sensitive tissues and prevents harmful bacteria from entering the damaged cavity, restores chewing function. Fillings are also important for the appearance of our smile, even though most of the time they are invisible.

All kinds of dental fillings are installed in the following cases:

• After endodontic treatment of caries, pulpitis and other diseases of the oral cavity.
• To prevent the development of caries in children.
• When erasing chewing teeth (molars) in case of violation of their mineralization.
• To make the design more durable and prevent the destruction of the remains of the tooth, a filling can be placed under the crown.
• After mechanical damage to the molars, in the case of the anterior incisors and canines, restoration is usually resorted to.
• To protect the tooth during long-term intracanal treatment.
• To give the correct shape to the molars in order to evenly distribute the load during chewing.

There are different types of dental fillings. Their classification depends on the filling material and the wearing period.

Types of fillings depending on the period of wearing

A variety of designs are available to patients. They differ from each other not only in the materials used, but also in the timing of wearing. Depending on this product can be divided into temporary and permanent.

Temporary fillings

The tab is used to protect the cleaned root canals during long-term treatment, which is carried out in stages. Most often, it is used in microprosthetics, because the manufacture of plastic fillings and ceramic inlays takes time.

Such fillings are placed in the treatment of diseases of the oral cavity, which are characterized by inflammation and the development of harmful organisms in soft and hard tissues. The dentist pours an antiseptic composition into the canal of the tooth, and so that it does not get into the mouth, the canal is closed with a material for temporary filling of the teeth.

For temporary filling, a special composition is used, which is called dentine paste. It is resistant to saliva and can cope with the mechanical stress of chewing food for some time. The product does not look very natural, but in this case it does not matter.

They put the structure for 3-4 days. In rare cases, it may stay for several weeks. The material simply will not last longer.

Permanent fillings

The service life of such tabs is calculated in years. Today there are materials that are excellent perform their functions even for decades.

There are already much more requirements for a permanent filling:

• The material must be chemically resistant to liquid, mechanical stress and acid-base environment of the oral cavity.
• A minimum percentage of shrinkage during solidification and sufficient plasticity to create a shape are required.
• The composition should not change color and stain the fabrics around it.
• The filling material must be completely safe.

In modern realities, an unremarkable appearance can be added to these conditions. Still, the tab also performs an aesthetic function, although this is not always especially important.

For the manufacture of long-wearing fillings, a variety of compositions are used. Some of them are already slowly going out of circulation, while others are just conquering this area.

Types of fillings depending on the material

If you understand the topic in as much detail as possible, you can highlight dozens of unique names. But some compositions differ only in the ratio of components, so it is more common to divide them into groups.

amalgam

The seal consists of an alloy of mercury, silver, tin and zinc. This medical metal is absolutely safe for human health, and products made from it have the following positive qualities:

• Metal inlays are both strong and plastic, so it is better to put such fillings on chewing teeth. The material is easy to give the desired shape, and the load on the jaw will be distributed evenly.
• The material has a uniform texture. In order for the surface of the filling to be smooth, it is not even necessary to polish it.
• The metal is not subject to abrasion. For this reason The lifespan of a filling on a tooth is up to ten years. and more.
• Despite the mercury in the composition, the alloy is completely safe. Even if the entire row is sealed, the amount of harmful metal will still not exceed the permissible norm.

Amalgam fillings on teeth

Such inserts are not used very often. All because of the contrasting appearance: when yawning or laughing, they immediately catch the eye.

plastic

These fillings are made from a polymer called acrylic. It is usually used in prosthetics due to its similarity to natural enamel and relatively low price. This is where the benefits end.

Pictured is a plastic seal.

Often, products are used as a temporary measure, if there is simply not enough money for a more advanced version. In all other respects, plastic seals do not perform well. The material wears off quickly. On molars, it lasts only a few months.

Acrylic has a porous texture. After installation, deposits accumulate on the plastic, which then serve as a breeding ground for bacteria. Not only the filling, but also the tooth suffers from them.

This feature of the plastic also affects the appearance of the seal. Even if it “behaves” excellently throughout its entire service life, it still won’t work to wear it all the time. Filling material tends to turn yellow that will be noticeable to everyone around you when you laugh.

Ceramic

Such a filling is a bit like a crown, but it is better known as a tooth tab. The material has several advantages over other options:

• It looks very natural, completely repeats the color and texture of natural enamel. Because of this feature, even incisors and canines are filled in a similar way.
• In terms of strength, ceramics can be compared with the protective layer of our enamel. With injuries in the jaw area, the material falls out much more often than breaks.
• The material is not subject to shrinkage and abrasion during chewing. Therefore, these fillings are excellent for restoring the chewing function and the appearance of the molars.

In the photo, a ceramic tab

The main disadvantage of ceramic fillings is their price. Moreover, the material itself is quite inexpensive, you will have to pay more for the work of a doctor. It takes a long time to make such a filling on a tooth, and it also requires experience and professionalism.

Photopolymer

Several compositional compositions can be attributed here at once. All of them are united by the fact that the material is placed in the root canal in liquid form and solidifies already inside. The polymerization of such substances occurs under the action of ultraviolet radiation.

Due to their good strength, light fillings can be placed on chewing teeth. At first, they shrink. The composites that make up the product, well repeat the appearance of the teeth. In the photo and in real life they are invisible. After hardening, the material has a very dense texture, which protects against the accumulation of deposits and the development of bacteria.

In the photo, a light seal

At the moment Composite fillings are the most widely used in dentistry.. With a large number of advantages, it also has an acceptable price. Therefore, not only dentists, but also the patients themselves, often opt for this option.

Glass ionomer

Glass ionomer and composite fillings can be grouped together. Both materials are called cements by dentists due to the fact that they harden after the root canal is closed.

Glass ionomer cement is distinguished by the presence of fluorine in its composition. This virtually eliminates the possibility of developing caries and other damage to the dentin after treatment.

This material is especially popular in pediatric dentistry. Sometimes they are filled with chewing teeth, even without expanding the root canal, simply to stop the development of caries. For the same purpose, glass ionomer products are sometimes placed under a dental bridge or porcelain crown.

Pictured are glass ionomer fillings.

Cement fillings on the tooth do not differ in special strength. They serve an average of several years. and may break due to strong mechanical impact.

In all cases, the production of the product consists of the following steps:

• Removal of damaged tissue.
• Root canal expansion.
• Installation of the seal itself.

Most often, fillings are used as part of the treatment of caries, so in the vast majority of cases, it begins with the elimination of this disease. With the help of a drill, the specialist removes all the tissues of the tooth, where the disease has already managed to penetrate.

If we are talking about deep caries, the roots are also removed. Otherwise, inflammation and development of pulpitis is possible. Such consequences are typical for all types of dental fillings, so it will not be possible to save the nerve endings.

After depulpation, the specialist slightly expands the tooth cavity. In this case, even healthy tissues are removed. The work is carried out with the help of a drill and is necessary simply to fill the tooth easier and faster.

Usually at this time, the specialist does not yet know exactly what types of dental fillings he will use. Even if the choice has been made, it can be changed depending on the situation.

It happens that at the beginning of treatment, the patient decides to put a light filling. Then it becomes clear that this is impossible, because most of the enamel is damaged, and the ceramic inlay will look much better. Be prepared for such unexpected changes.

Ceramic and plastic fillings are not placed immediately. It takes time to make them.

How much does a filling cost

In Moscow, prices for the simplest products start at 400 rubles. Composite fillings can cost up to 2 thousand rubles apiece. Ceramic inlays are the most expensive, as they are more related to microprosthetics. The price of the product does not even depend on the material, but on the complexity of the shape of the seal and the time spent on manufacturing. The more difficult the job, the higher the cost.

In public clinics, fillings are placed free of charge. Only the most affordable cement materials are used. If you want a higher quality product, you will have to pay extra.

Everyone will have to deal with a filling at least once, so this information will come in handy for everyone. If you don’t know what dental fillings are, then you simply won’t be able to choose the best option for yourself.

Setting a filling is the final step in the treatment of many tooth pathologies, whether it be caries, restoration after a chip, or restoration of enamel after.

Modern dentistry has a wide arsenal of various types of dental fillings. However, each has its own advantages and disadvantages.

What are the types of dental fillings and which ones are best used in each case?

Cement based filling

In the photo, a cement filling on a tooth

Since cement fillings have excellent adhesion, that is, they adhere perfectly to the surface of the tooth, they are very common in dentistry. These are durable, non-fragile elements that can stand for a long time.

There is one caveat: the density index of such fillings is higher than the density of tooth enamel, and over time, that part of the tooth that surrounds the filling wears out. As a result, a vulnerable zone is created along the edge of the filling, secondary caries occurs.

The compositions of cement fillings are divided into:

• for phosphate cements, which contain up to 90% zinc oxide, magnesium oxide, silica and phosphoric acid;
• for silicate-containing mixtures, with the content of aluminosilicate and phosphoric acid.
  Phosphate cements are not used for surface work, they close up channels, put under crowns or under the overlying layer.

Silicate cement is more similar to the natural color of the tooth and has a shiny surface. transparency. Since it is a very hard material, it is suitable for filling anterior teeth.

For deep filling, silicate cements are not used, as they adversely affect the soft tissues of the pulp.

Ercodont-cement is formed from a mixture of the above species. also suitable for different types of fillings.

To improve the quality of fillings, silver powder is added to phosphate compounds. These compounds are used when they are very inexpensive materials.

Plastic fillings

Plastics used in dental technologies harden quickly, have high hardness, strength, chemical resistance and do not irritate oral tissues.

The problem of their use is a decrease in their volume, over time, a person feels that the filling, as it were, has sagged, slightly decreased in size, which gradually leads to tooth destruction.

Plastic fillings also tend to stain and do not retain their original color for long. These fillings include acrylic oxide and carbodent.

Amalgam fillings

The quality of amalgam fillings, which are an alloy of mercury and metals, is very high.

Amalgams may contain silver, tin, copper, zinc, mercury. These are very plastic, well-adhering materials, which have great strength and serve for several decades.

The negative quality is that the material remains with a metallic sheen, so it is placed only in inconspicuous places. The body does not get mercury poisoning. The most commonly used silver amalgam.

The use of ceramics

The photo shows ceramic inlays on a plaster model

Ceramic fillings have high hardness and do not lose their size over time - shrinkage does not occur.

Ceramic fillings do not change their color, do not acquire dark shades or stains. This is, one might say, the perfect filling.

The filling is made in the form of an inlay based on a cast from a treated and disinfected tooth. Due to its configuration, the inlay distributes the load on the tooth more evenly when chewing, and holds on tighter.

There are different types of ceramics, for example, containing zirconium oxide - transparent and durable; pressed ceramics, cermets.

Light curing composites

Dental fillings made of light-curing composites are also called "light" fillings. Polymerization reactions in the substances that make up such fillings occur under the influence of ultraviolet radiation. healed teeth will shrink over time, but at first the fillings look perfect.

These materials are well polished, microphiles are used on the front teeth, macrophiles - on the more massive back ones.

Self-hardening material with particles of silicon and zirconium is used to restore the surface of chewing teeth. For hard-to-reach areas, flowable composites are used.

When setting the seals, each layer is illuminated, starting with the adhesive coating. A filling can cost upwards of $100 and must last at least 5 years.

Installation and characteristics of composite fillings:

Glass ionomer cement

This group of materials contains a significant amount of fluorine, which prevents the occurrence, and is good for healing teeth in children.

The negative properties are the fragility of the resulting material. These cements can be both self-hardening and light-curing, the dentist is comfortable when working with such a material, there is no rush to install.

Glass ionomer fillings, as in the photo on the right, do not always match the color of the tooth, you have to cover it with a composite material.

The cost of such fillings, depending on the complexity of the work and the use of light-curing composite materials, may vary.

Chemically Cured Composites

The main component of such compositions is porcelain, which determines the hardness and durability of the installed seals.

Polymerization shrinkage, which is a minus of these fillings, is compensated with the help of additional adhesive preparations that improve adhesion to the tooth tissue and prevent secondary caries.

The main advantage of chemically cured composites is that curing occurs evenly throughout the depth of the cavity.

Stages of setting a seal

When treating a diseased tooth, after establishing the primary diagnosis, the doctor removes the softened dentin, cleaning the surface of the tooth from the affected tissues. Already at this stage, patients sometimes require. With a deep lesion, a medical pad with calcium is placed to relieve inflammation.

Under the aesthetic surface of the filling, an insulating gasket made of high-quality materials with maximum adhesion is placed. The next step is the setting of the seal, if the material is light-hardening, then each layer of the seal shines.

Filling cost

The use of modern technologies with the use of expensive medical materials and filling compositions, the use of expensive equipment and the high level of skill of a dentist are significant costs.

Comfortable treatment of infected teeth costs a lot of money. The price for treatment, for canal filling if necessary, for the installation of a seal consists of different parameters.

In each individual case, the treatment is individual, sometimes a tooth can be healed in one visit, and sometimes the doctor and the patient have to meet three times.

All stages of treatment in summary:

• initial inspection;
• cleaning the affected cavity;
• drug administration;
• if necessary, an x-ray of the roots of the tooth is taken for accurate diagnosis;
• cleaning and shaping channels;
• removal of nerves;
• canal filling;
• setting or, as a consequence, a permanent seal.

Prices for all these stages are in the price lists of clinics.

The cost of filling a tooth can also vary greatly. Composite, light fillings can be an order of magnitude more expensive than cement ones.

The filling of the actual canal of the tooth, of which there are several in the tooth, also consists of separate stages - this is the biological treatment of each canal, closing the existing enlarged hole, covering the surface with a light-curing composite. The formation of prices in each clinic is based on the quality of the drugs used for treatment and filling, the range of which is different.

How much does it cost to fill a tooth?

Approximately current prices for fillings in Moscow:

Children's orthodontics and fillings on children's teeth in some cases are qualitatively different from adults, the installation of fillings for children is usually performed faster than for adults and the price does not exceed 2000 rubles.

Removing an old filling will cost about 400 rubles, applying a medical or insulating pad will cost from 700 to 2000 rubles.

Restoration of a tooth with a deep lesion with the installation of a light filling includes many parameters, and the filling itself will cost from 4,000 rubles. Anesthesia when working with a tooth costs 300-400 rubles, and it costs the same amount to perform an x-ray of the jaw area.
