Amalgam, the silver colored dental restoration material used to fill cavities, has received much attention as it contains small amounts of mercury.
However, the mercury is bound in a stable matrix and the level of mercury released is minimal. In 2020, the FDA published a report that certain groups may be at greater risk for potential harmful health effects of mercury vapor released from the device.

Options include waiting until after these periods or using alternatives such as composite resin, glass ionomer, porcelain, and gold.
Composite resin is most popular due to being white and moderate cost.
