Mercury dental filling, or best known as dental amalgam is an alloy of silver, tin, mercury, and copper as it’s constituent. The term amalgam is also used as a synonym by the dental profession. Among all, silver and tin have the highest composition within an amalgam.
The use of mercury in the oral environment has raised concerns regarding safety. Currently, several countries have banned the use of dental amalgam because of environment concerns, as well as alleged side effects that may be sustained by patients who receive dental amalgam restorations.
