Amalgam is a material used by dentists to fill in cavities. It is also called a filling. Dental amalgam is composed of mercury combined with silver, copper, zinc, tin, and sometimes beryllium or palladium. Dental amalgam is known for its solidity and durability, the ease of putting it in, and its low cost. However, it is criticized for the potential toxicity of the mercury it contains and its unsightly appearance.
