Dental caries

The most common reason to consult a dentist is caries and its complications: pulpitis and periodontitis. If oral hygiene is unsatisfactory, the enamel, and then dentine (the fundamental substance of the tooth) is damaged under the influence of acids produced by the microorganisms, and a cavity develops.


Dental caries usually starts with the discolouration of enamel which looks like a spot or a darkening in the natural enamel fissures. The tooth can become sensitive to chemical irritants or temperature stimuli. Later, when a tooth cavity develops, there may be a feeling of food compaction, fleeting pains while eating sweet foods or due to temperature stimuli (hot or cold food). If dental caries develops under a tooth filling, as a rule, you can notice a dark rim along the filling border.


At the early stages caries can be treated by remineralization (restoration) of enamel or it can be stabilized by means of impregnating the enamel with a special paste. This way of treatment does not involve cavitation, or tooth drilling. If there is a cavity, it is necessary to fill it or restore with an overlay.


This is probably the most popular way of restoring the shape and the colour of the tooth.

Historically, amalgam and special cements were used for tooth filling. In the secold half of the 20th century, polymer (acrylate-based) materials began to be used. A revolution in tooth filling as a means of tooth restoration took place when light-polymerized materials first appeared: these are materials whose polymerization takes place when they are exposed to light waves of a certain length.

Most commonly, light-polymerising fillings are used for permanent fillings or for correcting the shape and colour of the front teeth (the so-called ‘direct veneers’). Using such a material does not necessarily ensure a durable and aesthetically satisfactory result: a lot depends on the manufacturer and the quality of the material, on the doctor’s ability to feel the colour and shape of the tooth as well as on the technology compliance. It’s not always reasonable to yield to the temptation of restoring a major defect of dental tissue (fundamental substance of the tooth) quickly and relatively cheap: using an overlay or a dental crown could be more reliable.

 When do we have to do that?

We resort to it in case of small or medium-size carious cavities, certain cases of restoring tooth stumps, some cases of the change in the colour and shape of the front teeth, or for the temporary restoration of a decayed or missing tooth.

How long does it take?

As a rule, one visit is enough for tooth filling and takes from one to two hours.

How much does it cost?

The price depends on the degree of the tooth deterioration, on the material used, and on the aesthetic requirements. The minimum puice of a light-polymerising filling starts at 1000 roubles.


Restoring a tooth with an overlay is probably the most reliable way of dental restoration after caries treatment. Overlys used to be very popular before the epoch of composite materials, especially in European countries. An overlay enables to restore the exact anatomic shape of the tooth, including its contact points (the points where adjoining teeth touch each other). Modern overlays are prepared with the help of digital dentistry (CAD-CAM dentistry) and are made of ceramics, polymerized in the factory environment. Due to this technology overlays are considerably more durable than composite fillings and enable to restore a tooth even when the degree of tooth deterioration is great. We carry out this kind of job with the help of Amann Girrbach equipment, which gurantees a high precision and, consequently, a high reliablilty of the restoration.

When do we have to do that?

We resort to it in case of medium destruction or considerable destruction of the crown, as an alternative to metal overlays or as an alternative to crowns on devitalized teeth.

How long does it take?

As a rule, two visits are required for tooth restoration.

How much does it cost?

The price of an all porcelain restoration produced with the CAM-CAD technology is about 19,000 roubles.
