      Dental Amalgam Regulatory Information

      ​Dental amalgam is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper. Mercury is a potent neurotoxin that bioaccumulates in fish and shellfish. Mercury-containing amalgam wastes may find their way into the environment if improperly managed by dental offices. Consequently, the Environmental Protection Agency promulgated the Dental Amalgam Rule to regulate the discharge of mercury from dental facilities.
