Little evidence to link mercury fillings to human health problems

h year. Dentists use dental amalgam because the material is durable, easy to work with, and can be placed rapidly into a prepared tooth.

The Controversy

Despite its long history of use, dental amalgam has stirred controversy due to its mercury content. For nearly a century, concerns have been raised about the potential adverse human health effects that may arise from the inhalation and absorption of mercury vapor from dental amalgam. Opponents claim that mercury release from dental amalgam leads to a variety of health problems after its placement in the mouth.

Numerous government and independent agencies have examined the safety of dental amalgam and have concluded that the scientific evidence consistently demonstrates the human body absorbs mercury vapor released from dental amalgam restorations. Despite this absorption of mercury, scientific panels assembled by the U.S. Public Health Service, the European Commission and the World Health Organization (WHO) have concluded there is no scientifically relevant and definitive evidence to demonstrate a causal link between dental amalgam and adverse health effects, except in rare instances of allergic reactions. At the same time, some governments have recommended against placement of dental amalgam restorations in certain patient populations.

The Study

LSRO was tasked to examine the peer-reviewed, primary scientific and medical literature published between January 1, 1996 and December 31, 2003 relating to dental amalgam and human health. The purpose of this review was to:

provide information about the absorption and distribution of mercury in the human body,

evaluate the findings from the recent scientific and medical literature, and

identify research gaps that when filled may definitively support or refute the hypothesis that dental amalgam causes adverse health effects.
