In the past, teeth were most commonly repaired with amalgam (silver) fillings or gold restorations. Although gold is the most durable and stable material for fillings, it is not aesthetic .Thanks to advances in modern dental materials and techniques, teeth can be restored to a more aesthetic and natural appearance. There are different types of cosmetic fillings currently available. The type used will depend on the location of the tooth and the amount of tooth structure that needs to be repaired.
