What Are Amalgam Fillings?
Dental amalgam is a dental filling material used to fill cavities caused by tooth decay.
Dental amalgam is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper.
Approximately half (50%) of dental amalgam is elemental mercury by weight.
If you have an amalgam filling, it will release low levels of mercury vapors which can be breathed in and absorbed by your system. Although the health risk is small, some will be more vulnerable to their effects than others, such as pregnant people and children.
