There is a thin protective layer on the outside of our teeth called the tooth enamel. If your tooth enamel is decalcified so deeply that a hole forms in the tooth, you have a cavity. Dental fillings do exactly what it sounds like they do–fill cavities. This helps prevent further damage to your teeth.
We make use of tooth coloured composite materials to do fillings. The restored tooth’s appearance will remain unaffected, as the filling blends well with the surrounding teeth. A composite filling does not contain mercury.
Additionally, composite fillings can be fixed and repaired many times over, if needed, without the need of having to remove the original filling.
