National and international bodies have determined that the use of mercury-containing dental amalgams is safe.
The World Health Organization stated that "dental amalgam restorations are considered safe…", though the document goes on to note that there are instances of local allergic reactions or side effects.
The U.S. Food and Drug Administration (FDA) reviewed 200 scientific articles and an additional 70 relevant abstracts. FDA stated that "dental amalgam is a commonly used device with a low risk of adverse events reported to the agency".
The American Dental Association Council on Scientific Affairs wrote that "the scientific evidence supports the position that amalgam is a valuable, viable and safe choice for dental patients". This assessment was supported by a literature review which stated that "studies continue to support the position that dental amalgam is a safe restorative option for both children and adults". The paragraph continues with a statement about the important "distinction between known and hypothetical risks".
These reports, and a number of review articles with similar conclusions, are based on research which is abundant for children over the age of six and for adults. There are subsets of the population for which the research is less abundant; however, available summary research still supports the safety of dental amalgam use. Details and continuing research needs for special population groups are found below, in the section titled "The Evidence".
