Composite resin takes a little longer, though most people still prefer it because it creates natural-looking teeth. It takes more than one layer, and a special light is used to harden the area around the filling.
Dental fillings are used to treat different dental problems like cavities and broken teeth. Teeth are usually filled with a material called composite resin, which is designed to look like natural teeth. Fillings can also be done with gold, porcelain, or silver amalgam.
