Caries is the most widespread dental disease. It is important to detect and treat caries on time, so that damages would not progress, because defected tooth tissue will not restore itself on its own. Untreated cavities can lead to complications, which can cause the loss of teeth. We find it important for the treatment process to be as teeth-saving as possible for the patient and use aesthetic and quality filling materials in cavity treatment, which enable us to achieve very good and lasting results in restoring dental crowns and thereby preserve the mastication function of teeth.
