Amalgam Fillings

Amalgam is an alloy of mercury with various metals used for dental fillings. It commonly consists of mercury (50%), silver (~22–32% ), tin (~14%), copper (~8%), and other trace metals. Dental amalgam is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper dental filling material used to fill cavities caused by tooth decay. Approximately 50% of dental amalgam is elemental mercury by weight. The chemical properties of elemental mercury allow it to react with and bind together the silver/copper/tin alloy particles to form an amalgam.
