What are tooth-colored fillings made of?

Tooth-colored fillings are made of composite resin, which is composed mainly of plastic and silica. They contain no metal or mercury. These fillings are placed in layers with each layer being cured before the next one is added. The fillings bond to your tooth, making it stronger from the inside, and can also be placed in a single visit.
