Tooth colored fillings are made of a composite resin. This can be created with a combination of plastic, glass, ceramic, and other types of polymers to create the material the dentist prefers to use. Unlike silver metal fillings, composite resin fillings can be made to accurately match the color of your natural teeth for a seamless repair.
The material used to create these white fillings is safer than traditional metal amalgam, which generally contains a small amount of mercury. Additionally, healthy parts of the tooth need to be removed prior to using a metal filling over a composite resin filling. It does take a highly skilled dentist to properly use the natural-color fillings, so you may want to talk with a Los Angeles cosmetic dentist to further discuss which option is best for you.
