Silver-colored fillings—also called dental amalgams—are made of a combination of metals such as silver, tin, copper and mercury. White fillings—also called composite fillings—are made of plastic and ceramic.

What color is the filling for cavities?

White fillings can also be called dental composite and they are the tooth-coloured resins used to fill cavities. This composite resin is made of a blend of plastics and fillers such as silica and dimethylglyoxime which bond with the tooth's surface.

Are cavity fillings white?

White fillings are dental fillings made from composite dental resin. As their name suggests, white fillings are white, which means they blend more seamlessly with the rest of your teeth. No more flashes of silver when you speak or laugh! These days, white fillings are the standard among most dental offices.
