Composite Fillings
A composite resin is a tooth-colored mixture containing silicon dioxide glass as filler. Originally, these bonded fillings were confined to the front teeth because they were not strong enough to withstand the pressure and wear generated by the back teeth.
New advances in materials have allowed composites to be successfully placed in the back teeth as well. Composites are not only used for restoring decay but are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
