Fillings repair and seal damaged or decayed teeth with materials such as porcelain, silver amalgam or gold. Another technique is the use of direct composite bonding using tooth-colored composites to produce a natural finish.
Other than sealing cracks and cavities, fillings can be to smooth and even out the surfaces of the tooth for better appearance and functionality. It can also be an effective treatment so sensitive teeth.
Filling is carried out under local anesthetic. First unwanted areas such as decayed areas are removed using tools or laser. Then the area is prepped to receive the filling. Then a layer of adhesive is applied followed by the filling material itself. Light-cured filling materials are hardened with a blue dental light.
