A cavity is formed in the tooth because of tooth decay or if a piece of the tooth chips or breaks off. To prevent further damage from occurring to your tooth, it is important to stop the cavity in its tracks. The existing cavity should be filled and closed with a filling which need to fulfill certain standards:
There should be no gap between the tooth and its filling; it must be biocompatible, allow for normal chewing, last a long time and of course it needs to comply with the client’s aesthetic preferences.
The filling for every cavity can be fit to its specific dimensions. There are also multiple filling types to choose from: small- to medium-sized cavities can be filled with plastic fillings whereas moderate-to-large fillings offer inlay fillings or overlay fillings made out of ceramic.
