Tooth decay is the destruction of tooth structure. A dental filling is material used to restore form and function to the decayed tooth.

Tooth colored fillings are the newest type of filling in common usage. They are commonly known as white fillings. Tooth colored fillings were created as an alternative to traditional metal dental fillings. They are colored to look like natural teeth and are more aesthetically pleasing than amalgam (silver) or gold fillings. They are also strong, durable, and make for a very natural looking smile.
