Light filling - what is the best filling and how much does it cost?

Diana Levchuk. Founder and chief physician of aesthetic dentistry Deva-Dent. The doctor is an orthopedic dentist specializing in aesthetic treatment and prosthetics. Has 15 years of experience in therapeutic and orthopedic dentistry.

The reason for writing this article was a question that is often asked, especially from the regions of Russia:

“The clinic advised me to get a paid light filling, but how is it better than the usual free one?”

In such a situation, most patients agree to a “paid” or more expensive filling. However, having already agreed, such a patient has little idea what it is and what he has to overpay for. But the price of a light-curing filling can also be different and sometimes differ significantly!

Well, let’s try to “put everything into pieces.”

Requirements for filling materials

The main requirements that filling materials must meet, regardless of service life and purpose of use, are:

• Biological safety;
• Hypoallergenic;
• Easy to install and remove;
• Strength;
• Loyalty to medicines;
• Good resistance to mechanical loads and aggressive environments.

Modern dentistry has a large selection of filling materials.

In this regard, dentists quite often ask their patients questions regarding the choice of filling material, offering various types of dental fillings. To make it easier to make a decision, it is necessary to take a closer look at all types of fillings used in dentistry.

Care

The rules for caring for photopolymer fillings are practically no different from ordinary oral hygiene.

Toothache after filling when biting

Most people monitor the health of their teeth and promptly contact the dentist at the first negative signs.

Patients simply need to brush their teeth regularly with a soft toothbrush and rinse their mouth with warm water or a special solution after each meal.

It is also important to regularly, at least once every six months, have a routine examination with a dentist. Only if problems are detected in a timely manner can they be easily eliminated and the development of more serious diseases prevented, and accordingly preserve the integrity of the tooth that has been restored.

Temporary fillings

The second name for this type of dental fillings is diagnostic. Thus, caries damage can spread not only to the tooth enamel, but also to deeper tissues: dentin layers and pulp. Installing a temporary filling allows you to determine how deeply damaged the dental tissue is. In cases where we are talking about the development of pulpitis, the reaction to temporary filling material will be pronounced pain. Temporary fillings are used not only to detect pulpitis, but also as a sealing agent in case of long-term treatment, which involves the use of drugs placed in the cavity. Criteria that temporary filling materials must meet:

• Good performance in terms of tightness;
• the ability not to come into contact with drugs introduced into the cavity;
• ease of installation and removal;
• biological safety and hypoallergenicity;
• high curing rates in a short period of time.

The service life of temporary fillings ranges from several days to 3 weeks. Installing a temporary filling is similar to permanent filling and requires compliance with the same rules, namely:

• Filling is carried out after preparing (drying) the surface to be sealed;
• It is recommended to refrain from eating and drinking hot drinks for 1-2 hours.

In cases where the patient has been diagnosed with pulpitis, a temporary filling is installed in two layers. In this case, the top layer acts as a sealing gasket that isolates the pulp, and the second layer includes the drug.

It must be taken into account that temporary fillings do not have the same strength and resistance to mechanical loads as permanent filling materials. Due to this aspect, it is not recommended to brush your teeth too actively or eat solid foods until the temporary filling is replaced with a permanent one. An unpleasant bitter taste in the mouth and the presence of pieces of material may indicate partial destruction of the temporary filling. The destruction of the material can occur as a result of improper care, neglect of the doctor’s recommendations, or if the installed filling was of poor quality.

What is

Probably every person at least once in his life has had to resort to treatment and installation of a filling on a tooth. But rarely does anyone think about what material these products are made of, as well as what types of fillings exist currently. But in vain, knowledge of these features will help you choose the most suitable filling that will last a long time, and sometimes it can completely imitate dental tissue. In addition, it is worth considering that the process of installing a filling is a rather labor-intensive process that requires increased professionalism from the doctor so that the material lasts a long time and does not fall out of the tooth a few days after installation.

Black carious formations provoke pulpitis (nerve inflammation), this occurs as a result of infection entering the tooth cavity where the neurovascular bundle is located. But inflammation of the nerve in the tooth does not develop immediately, but only when the carious cavity becomes deep enough.

In the dental field, a filling is understood as a special material that has high viscosity, but at the same time it hardens quite quickly. Using this material, the doctor fills the area of ​​the tooth that has been cleared of caries or pulpitis. In addition to filling holes, this material is often used to hide damaged enamel or other defects. But it is worth remembering that the more reliable the structure of the filling, the better the tooth will perform its natural functions. Nowadays there is a wide variety of materials that are used for filling teeth. Dentists use metal, plastic, and ceramic bases as fillings; fillings made from different types of cement are also often used. In addition, they are divided into temporary and permanent fillings.

Types of temporary fillings based on the materials used

On water dentin

Kaolin powder diluted with liquid is used as a derivative material.

From dentin paste

To create a filling, a mixture of kaolin powder and peach oil is used.

Cement based

The basis of such a filling is zinc phosphate cement, which can withstand severe loads. In this regard, this type of temporary dental fillings is used in the treatment of chewing teeth, which account for the majority of all impacts.

Made from polymer materials

Pastes made from polymers have a light-curing mechanism.

Permanent fillings

They are characterized by high strength and long service life. The service life of permanent fillings depends on the material of manufacture and the loads applied. In connection with the above, it is extremely necessary to compare as accurately as possible the level of expected load and the properties of the filling material.

The main purposes of installing permanent fillings are:

• The need to seal cavities formed as a result of therapeutic measures;
• reconstruction of lost or damaged areas.

In some cases, damage to teeth (chips, cracks, etc.) can be compensated for without resorting to prosthetics, but through correction (reconstruction) using filling materials. Requirements for permanent filling materials:

• Biological safety and hypoallergenicity;
• High levels of aesthetics;
• The ability to withstand mechanical loads without losing its qualities.

How does the installation work?

In addition to choosing the necessary material for filling a tooth, it is worth knowing the features of installing these products. This process has certain features on which the service life of a particular filling product depends. Features of installing seals:

1. First of all, an examination of the diseased tooth is carried out and an accurate diagnosis of the lesion is established, and the area of ​​damage is determined;
2. Next, the tooth is treated with special preparations, the cavity and surface of the tooth are cleaned of damaged tissues;
3. Typically, during treatment and cleansing, the doctor performs local anesthesia using various anesthetics. The choice of anesthetic depends on the strength of action and on the individual characteristics of the patient’s body;
4. During deep lesions, a special pad with calcium is placed, it will speed up the process of relieving the inflammatory process;
5. An insulating gasket is placed under the aesthetic part of the filling material, which is made of high-quality materials with a high degree of adhesion;
6. The next stage is to install the filling material;
7. If material is installed with a light-hardening base, then each layer of the filling product shines.

Types of permanent fillings for teeth

Modern types of fillings in dentistry are distinguished by great variety, which is expressed in the levels of strength and durability, hardening speed, aesthetic appeal (the possibility of the most accurate imitation of natural tooth enamel). The pricing policy for different types and types of dental fillings is built based on the qualities of the filling material, and almost always meets the price-quality criterion.

Cement fillings

This type of filling has an affordable price and fairly good resistance to mechanical loads. Medical cement has good adhesion and hardens quickly. However, it must be taken into account that cement usually has a higher density than natural tooth tissue. In this regard, one of the negative aspects of using such fillings is the possible wear of the dental tissue adjacent to the filling material, which can lead to the development of secondary caries.

Depending on the basic composition, there are two types of fillings made from medical cement: mineral and polymer.

Mineral fillings

As the name suggests, the composition of such fillings is based on minerals of natural origin:

Zinc phosphate cements

They are a powder containing oxides of zinc, magnesium, aluminum and silicon. Mixing the powder with an aqueous solution of phosphoric acid leads to the formation of a substance that does not dissolve in the oral cavity. Phosphate cement fillings are generally not used for surface sealing. The main direction of their use is filling of canals and the lower layer. The service life of fillings made from zinc phosphate cements usually does not exceed 2 years. The advantages include low cost. The disadvantages of zinc phosphates include: low strength, aesthetic unattractiveness, poor adhesion.

Silicate cement

The material contains aluminosilicates and orthophosphoric acid. A distinctive feature of this type of cement is the ability to release fluoride ions, which serve to prevent the development of secondary caries. The use of this type of filling is not advisable in cases where deep filling is necessary, since it requires the installation of a gasket that protects the dental pulp from the toxic effects of released free phosphoric acid. Silicate cement has the necessary transparency and smoothness, which allows it to be used for filling front teeth.

Silico-phosphate cements

They are a combination of silicate and zinc phosphate. This composition makes it possible to minimize the manifestation of shortcomings that occur in each of the components separately. Thus, the combined material has higher strength and better adhesion to tooth tissues.

Polymer fillings

Fillings consisting of polymeric materials are usually divided into:

Glass ionomer

They are a combination of crushed glass, fluorides and polyacrylic acid. Hardening occurs as a result of a chemical reaction. The most modern glass ionomers harden under the influence of a special lamp. The use of these types of light fillings does not imply any restrictions on food intake. You can eat and drink immediately after the filling material is installed. The advantages of GIC include: good adhesion, hydrophobicity, plasticity (usually they do not have problems with modeling), aesthetic appeal and the ability to release fluoride ions, which are a prophylactic agent. The disadvantage of this material is its fragility, leading to rapid abrasion. The service life of GIC fillings usually does not exceed 3 years.

Polycarbonate cements

They are an analogue of zinc phosphate, improved by enhancing adhesive properties, better biocompatibility and less tendency to dissolve. The main target areas are: fixation of orthodontic structures, filling of baby teeth in children. Almost all cement fillings are chemically cured materials. The main areas of use are:

• Children's dentistry;
• Temporary filling;
• As a fixative in orthodontics.

Plastic fillings

This type of filling has become quite widespread. It compares favorably with cement materials in a number of positive qualities. Advantages of plastic fillings:

• Higher plasticity rates than cement;
• Fast hardening;
• Good hardness and strength;
• Chemically resistant;
• Correctness regarding oral tissues;
• Aesthetic appeal.

Plastic fillings vary depending on the materials used. It is customary to distinguish:

Acrylic fillings

They have aesthetic appeal and, thanks to a wide range of shades, can be used even on visually visible areas of the dentition. It must be taken into account that plastic is a porous material. In this regard, it is not recommended to install acrylic fillings for deep caries damage. This is due to the fact that the porous surface of the filling can become a favorable environment for the accumulation of bacterial plaque, which can lead to a number of serious diseases. In addition to the above, such fillings are not recommended for smokers and people who regularly consume foods with large amounts of coloring substances. Exposure to coloring pigments can radically change the color scheme of the filling.

Epoxy fillings

As the name suggests, they are made on the basis of epoxy resins. They have good strength and durability. They have a less pronounced toxic effect than acrylic materials. The main disadvantage is the tendency of such materials to darken after 2-3 years. In this regard, the main intended use of epoxy-based fillings is filling chewing teeth. Disadvantages of plastic fillings:

• Tendency to settle. Even modern materials show noticeable shrinkage after 2-3 months;
• Change in color under the influence of dyes;
• Toxicity.

Amalgam (metal) fillings

The material is an alloy of metal and mercury. Silver, copper and tin are most often used as metal components. The choice of metal is individual and different clinics may use different metals. Amalgam filling material has good strength and durability. Advantages of amalgam fillings:

• Not subject to corrosive damage;
• Has fairly high plasticity;
• Has high strength indicators;
• Virtually indestructible;
• If silver is used as a metal component, the composition has antiseptic properties.

Despite a fairly large number of positive qualities, amalgam fillings are used extremely rarely. This is due primarily to the toxicity of the mercury contained in the composition and a number of difficulties that arise during the work process.

In addition to the above, amalgam filling material has other disadvantages:

• Allergenicity;
• Unattractive appearance;
• Poor adhesion to tooth tissues;
• Low adhesion rates;
• A dark color that can give an unattractive tint to the entire tooth.

There are a number of absolute contraindications to the use of such materials:

• The patient has metal structures;
• Age restrictions;
• Individual intolerance and tendency to allergic reactions;
• Dental units located in the visual visibility zone.

The service life of amalgam fillings can be up to 10 years.

Ceramic fillings

Recognized as one of the most aesthetically attractive and reliable filling materials. Most often, ceramic fillings are installed using the inlay method, which completely follows the shape of the tooth. Such fillings have practically no disadvantages, but are used quite rarely. This is due to the high cost and rather long production time in laboratory conditions. The service life of such fillings can exceed 10 years.

Light-curing (photopolymer) fillings

The composition of the material used for the restoration of chewing teeth includes particles of silicon and zirconium. For the treatment of hard-to-reach areas, fluid-flowing composite materials are appropriate. During the work, the material is applied layer by layer until the tooth surface is completely restored. A dental ultraviolet lamp is used to harden the material. Photopolymer fillings are recognized as one of the highest quality filling materials. The advantages of light fillings include:

• Almost complete visual identity with natural teeth;
• High levels of strength and durability;
• Aesthetic appeal;
• Possibility of selecting the required shade characteristic of natural teeth;
• Almost complete biological safety of the material;
• Resistant to shrinkage and abrasion;
• Long service life from 5 to 15 years.

A relative disadvantage of light seals is their price, which significantly exceeds the cost of the previously listed materials.

Composite fillings

The material used includes plastics and inorganic fillers. This combination in the composition allows you to achieve good ductility and adhesion, expand the color range and enhance the strength characteristics of the material. It is customary to distinguish several main types of composite fillings:

Light-curing

An ultraviolet dental lamp is used to harden the material.

Chemically curable

The material contains porcelain, which extends the life of the filling and increases its strength. Composites of this type are characterized by uniform hardening and good adhesion to tooth tissues.

Gutta-percha

A material used exclusively for filling the roots of teeth. Gutta-percha is characterized by increased strength, durability, lack of shrinkage and abrasion.

What does the cost depend on?

Everyone probably knows that treatment and installation of a filling is quite expensive. This depends on many factors that the doctor takes into account when determining the total cost. Typically, when treating and installing a filling product, the following important components are used:

• Expensive medicinal materials;
• High-quality filling compounds;
• Use of expensive equipment;
• Highly professional dentist.

Therefore, you should not be surprised that comfortable treatment, infection and filling of teeth will cost a tidy sum. However, the cost may differ each time. Sometimes you can cure a tooth in just one visit, and sometimes several visits may be required, and the cost will vary significantly. In addition, the cost depends on the stages of treatment. Typically, all dental clinics have a standard list of treatment stages, which includes the following services:

1. Initial examination;
2. Cleansing the affected area;
3. Administration of the drug;
4. If the need suddenly arises, an X-ray examination is required, in which a photograph of the tooth roots is taken;
5. Carrying out cleaning and formation of channels;
6. Removal of nerves;
7. Canal filling;
8. Installation of a temporary filling;
9. Installation of a permanent filling.

The cost of all these services can be found in clinic price lists. In addition, the cost may vary depending on the type of filling. Fillings made from a composite or luminous material will be much more expensive than simple cement or plastic products.

Criteria for choosing a filling

When choosing a filling, you need to consider the following aspects:

• The degree of expected load;
• Size of the surface to be filled and general accessibility;
• Requirements for aesthetic appeal;
• Biological safety level;
• Process depth;
• Patient's age.

Light fillings are recognized as the most popular and have virtually no negative qualities. In terms of characteristics, only ceramic fillings can surpass them. It is worth considering that the latter are significantly more expensive than all other filling materials. Filling materials used for the treatment of baby teeth deserve special attention. Most often, cement fillings are used in this direction.

This choice is due to the fact that baby teeth are subject to replacement and, as a rule, deep caries is not typical for them. Accordingly, the main negative properties of cement fillings are not important for them. Any questions you may have can be discussed with your doctor. He will also determine which material is more appropriate to use in this case.

Indications and contraindications

There are a number of indications for which the use of photopolymer materials is used. The main ones:

• tooth fracture;
• change in color of enamel that cannot be bleached:
• significant defects of tooth enamel;
• the presence of large fillings in the cervical area;
• noticeable interdental gaps;
• the need for minor correction of the position of the teeth;
• damage to the crown by a maximum of forty percent.

Even if there are indications for installing a filling, a specialist may refuse to carry out the necessary treatment. Among the main contraindications for installation are the following:

• bruxism;
• severe destruction of the front teeth;
• active development of caries;
• teeth subjected to intensive fluoride treatment;
• lack of proper oral hygiene.

Some of the contraindications are classified as conditional. Over time, they can be eliminated, and, accordingly, there will no longer be barriers to installing fillings made of photopolymer materials.
