Amalgam reactions are a rare occurrence. Reactions due to amalgam include lesions, hypersensitivity, and allergic reaction. It has been reported that there are less than 100 cases of amalgam reactions on record.

There has been several scientific studies indicating that there is no harm in using amalgam fillings. There has been little data to support claims of neurological damage or developmental effects in individuals with dental amalgams.

The Food and Drug Administration has examined amalgam reactions as well as the safety of amalgams extensively over the past several years. There are several educational efforts as well as regulatory changes being made by the Food and Drug Administration.

The only reason there is such a decline in the number of dental amalgams currently being performed is due to new technology, not because of safety issues. Dental amalgams have been used for over 100 years and will continue to be used.

At this time there are no restrictions on the use of dental amalgams. The risk of reaction due to dental amalgams is extremely rare, and only causes minor and temporary allergic reactions.

Alternative materials can be used when requested or due to a major restoration. Dental amalgams are not used in individuals having major restoration done. There is several clinical trials as well as ongoing research on amalgam reactions.
