Are amalgam fillings safe?

Silver fillings in Dillon, CO | Summit Dental GroupMany groups have expressed concern in the past several years over the use of amalgam fillings (also called silver fillings). Dental amalgams contain low levels of mercury, and this has led many people to believe that these fillings are linked to a number of conditions including Alzheimer’s, autism, and multiple sclerosis.

Public Health Agencies on Amalgam Fillings

A number of public health agencies like The American Dental Association (ADA) and the FDA have confirmed the safety of dental amalgams and stated that there is no scientific basis for the link between mercury-based fillings and these or other conditions. The fact is that there is no known cause for these conditions and no evidence to support the claim that removal of amalgam fillings can cure these or any other condition.


The mercury in dental amalgam is mixed with other metals like silver, copper, tin and zinc to create a stable alloy that has been safely used by dentists for over 100 years to fill cavities and preserve the decayed teeth of millions of patients. The FDA reconfirmed the safety of dental amalgams in March of 2002, and in 2006, the National Institutes of Health concluded several large-scale studies that further supported the earlier findings of the FDA.

Additionally, the concern over adverse health effects resulting from the very small amount of mercury vapor released from amalgam fillings has been found by the ADA to have no scientific basis. In fact, consuming seafood is likely to expose you to more mercury than the vapor that is released from amalgam fillings.
