Types of tooth fillings
Tooth filling or restoration is the process of restoring the full anatomical shape of the tooth so that it can perform its function in the future.
Fillings can be:
Temporary fillings are installed during root canal treatment, their main task is to close the cavity of the tooth and prevent food from getting in or infecting the root canals.
Permanent fillings are made of materials that allow reproduction of the anatomical shape of the tooth and withstand chewing pressure.
Various types of cements (such as glass ionomer) and photopolymer materials are used as materials for permanent fillings.
What should be a good material for tooth fillings?
At iStomatolog dental clinic in Kyiv, we use certified photopolymer materials and glass ionomer cements from Ukraine, Europe, and America that comply with WHO standards.
Stages of tooth filling:
Removal of decayed tissue from the tooth
Isolation of the tooth with a rubber dam
Sterilization of the tooth surface with HealOzone or a laser
Polishing and shaping the filling

Tooth filling with photopolymer materials
A photopolymer filling is a multi-component filling material that changes its physical state under the influence of light of a specific wavelength. After the composite has hardened, the filling adheres tightly to the tooth tissue, acquiring maximum strength. Photopolymers are the most popular materials in modern dentistry, used in the treatment of caries and tooth restoration.
The composite material consists of a volumetric organic matrix, inorganic additives, and a bonding agent (silane). There are various types of filling materials used for dental restorations, which differ in composition and ratio of structural components:
- Macrofillers, characterized by high strength and hardness, are used for filling chewing teeth (molars). Over time, the composition may slightly change color and lose its initial smoothness, but this will not affect the functionality of the tooth.
- Microfillers are formed by fine-dispersed structures, do not undergo pigmentation, and maintain a stable color and natural shine typical of tooth enamel. This material is used for filling front teeth to preserve the aesthetics of the smile.
- Nanohybrid fillers, or nanocomposites, are a multi-component material, where one of the fractions has particle sizes of 40-60 nm (1 nanometer equals 0.001 microns). The basis of the composition is an organic matrix, and additional components are inorganic polymers, represented by various resins, light absorbers, stabilizers, and other ingredients.
Nanocomposites used for dental restorations differ in composition. Materials based on titanium silicate, quartz, certain polymers, zirconia dioxide, and ceramics are used in dentistry. Nanocomposites also differ in the form of release, polymerization method, color shades, degree of transparency, and several other parameters.
The use of nanohybrid fillers for dental restorations has allowed dentists to achieve high aesthetic results without sacrificing strength characteristics, which was previously impossible. The dentist had to look for a compromise solution, sacrificing either aesthetics or strength. Materials with nanoparticles are distinguished by restorative reliability, minimal shrinkage during solidification (no more than 1.8%), sufficient plasticity, and a wide range of color shades.
The choice of photopolymer for dental restorations depends on the location of the tooth, the scale of the carious cavity, and the presence or absence of associated problems.
Composite materials are used:
- for treating caries and other types of tooth decay;
- for restoring dental crowns (shape, color);
- within the framework of artistic restoration of teeth;
- for eliminating some enamel defects (non-caries);
- for correcting the shape, size, or color of teeth.
The main advantages of composites used for tooth fillings are high plasticity, resistance to the effects of coloring agents (pigments), quick curing, and high aesthetics. The price of a filling depends on the type and volume of composite used, as well as the complexity of the task facing the dentist.
Application of liquid and "hard" photopolymers
"Hard" and flowable compositions are used for filling teeth. Liquid composites are placed in syringes and applied to the treated area using a special cannula. This category of filling material is used as an insulating lining for smoothing the surface of the cavity walls and compensating for shrinkage. Sometimes it can be used in the treatment of interproximal caries to restore the anatomical contact point between the teeth (however, due to the low filling with hard particles, such fillings may not withstand chewing load). Liquid photopolymers provide even distribution of the composition over the surface and create a tight contact with the tooth tissues.
"Hard" composites (with high filling with hard particles) are used for the restoration of teeth and the reconstruction of the anatomical shape. They have high strength, plasticity, the ability to retain the given shape, low shrinkage, and high wear resistance. Photopolymer material is applied to the tooth cavity in layers, each of which is exposed to a photopolymer lamp with a specific wavelength of light.
Features of installing a photopolymer filling
After removing damaged tissue and cleaning the area, the dentist selects the color of the composite using a special shade guide to match the natural tooth in shade and translucency. The cavity of the tooth is treated with a special composition to improve the quality of the bond between the tooth tissues and the polymer.
The photopolymer material is applied layer by layer, with a photopolymerization lamp used at each stage to cure the filling. Finally, the shape is adjusted according to anatomical parameters, the surface is polished using pastes and rubbers of various degrees of abrasiveness. In the first few days after treatment, consumption of products with active pigments (juices, berries, etc.) should be limited.
Contradictions to the installation of a photopolymer filling
There are actually few contradictions to tooth filling with composite materials: tooth fracture, serious defects in tooth enamel, damage to the tooth crown by more than 50 percent, uncontrolled bruxism. The wide selection of composite materials by composition and properties makes it possible to restore teeth even in complex cases with large areas of crown damage. Dentists evaluate the feasibility of restoration using composites and also select filling material based on diagnostic data.
Tooth filling with glass ionomer cement
Glass ionomer cements are widely used in tooth restoration and treatment of deep caries or acute carious processes. These materials can be both chemically and light-cured (the latter have quite high aesthetic characteristics). The filler for filling material is aluminum silicate glass with added fluorides, and the polymeric matrix is formed by polycarboxylic acids.
Glass ionomer cements have the ability to release fluoride, which protects teeth from further caries development for a long time, thus avoiding such a complication as pulpitis of the tooth with very deep caries or its acute form.
The main indications for choosing this material for tooth filling are:
- treatment of acute and deep caries of teeth;
- as a therapeutic lining;
- sealing fissures;
- tooth restoration for non-carious destruction of the tooth;
- making occlusal inlays for a crown;
- fixation of pins.
Glass ionomer cements form a strong bond with tooth tissues and other materials used during tooth filling, ensuring a high strength of the filling's adhesion to the walls, reducing the likelihood of secondary caries development under the filling, and the occurrence of complications such as tooth pulpitis. They also exhibit minimal shrinkage after hardening and sufficient plasticity to withstand chewing pressure.
Choosing a glass ionomer cement for tooth filling involves considering several factors. Glass ionomer cements can be in the form of a powder mixed with a liquid component or in special capsules (which are installed in a centrifuge for final mixing). The material may include a light-cured component, resulting in final polymerization occurring after exposure to a photopolymerization lamp.
Cements with increased silicon dioxide content are used for the restoration of the aesthetics of teeth. These compositions are chosen for small defects when the carious cavity has small sizes and depth.
Reinforced cements contain metallic additives that reduce the aesthetic properties of the filling but increase its resistance to mechanical and moisture influences and accelerate the hardening process. Reinforced mixtures are used to restore damaged baby teeth, fill permanent chewing teeth, and install temporary fillings.
The neutral composition of glass ionomer cements and ease of use allows for their use in pediatric dentistry, treating caries and non-caries pathologies. However, drawbacks of this material series include long hardening time, insufficient plasticity, and aesthetic properties (compared to photopolymers).

Reviews about iStomatolog
Що мене очікувало в центрі iStomatolog.
1. Відсутність очікування біля кабінету.
2. Відсутність зайвого. Персонал і лікарі тебе не обтяжують. Їх стільки, скільки має бути.
3. Без сумніву професіоналізм. Тебе вислухать, і обов'язково запропонують варіанти лікування. Що безцінно, це те, що тобі в першу чергу будуть пропонувати максимально зберегти свої зуби.
4. Відсутність бажання затягнути процес лікування на рік (якщо у тебе проблема не одного чи двох зубів). Головне, щоб дозволяли працювати ясна (їх стан).
5. Матеріали з якими працюють лікарі. Це виключно японський виробник.
І нарешті результат, який я навіть вже і не очікувала.
Лена, дякую тобі ВЕЛИЧЕЗНЕ за твою роботу. Тобі і твоїй команді.
Всі лікарі уважні, професійні, з щирою турботою про пацієнта. Запам'яталось, як мені років п'ять тому довго і терпляче спасали майже безнадійний зуб, зіпсований в іншій клініці — спасли, стоїть свій зуб, а міг би вже бути імплант.
