Dental amalgam is a dental filling material which is used to fill cavities caused by tooth decay. Its primary component is elemental mercury.

Tooth decay results in a loss of tooth structure. Dental amalgam is one type of dental filling material used to repair tooth structure that has been destroyed by decay and to restore the biting surfaces of a decayed tooth. Other materials, commonly referred to as composites, are also used for dental fillings.
