Amalgam fillings - safe?
What are the risks of mercury poisoning from amalgam fillings?
Amalgam fillings have been used on hundreds of millions of people since they first became available over one hundred years ago. The major components of amalgam are mercury, zinc, copper, tin and silver. When these elements are mixed they form a very stable and durable compound. Various studies have been conducted to investigate the claims that amalgam fillings might be harmful. These studies involved measuring the amount of mercury on the breath, in the blood and in the urine. The amounts of mercury detected were minuscule and amounted to barely detectable levels of the order of a billionth part of a gram. Various reputable authoritative groups, including the WHO, FDA (Food and Drug Administration) in the United States and various national dental associations have all concluded that there is no evidence to support the claims that amalgam fillings are dangerous. In conclusion, amalgam fillings are safe.
