Dental Amalgam Toxicity

Record	OBS-0323
Category	Health/Vaccines
Status	DEBUNKED
Summary	Proponents claim that dental amalgam fillings, which contain about 50% mercury, release toxic mercury vapor that can cause a wide range of health problems, including neurological, kidney, and immune system damage. They argue that mercury exposure from fillings is unsafe and can lead to chronic mercury poisoning. The scientific consensus, however, is that dental amalgam is safe for the vast majority of people, with only minor releases of mercury vapor that do not cause adverse health effects.
Origin	Concerns about mercury in dental amalgam have existed since the 1840s, when the American Society of Dental Surgeons denounced its use. The modern debate continues, with advocacy groups like IAOMT and holistic dentistry websites promoting the toxicity claims.
Claimed	Dental amalgam fillings are approximately 50% mercury and continuously release mercury vapor. Mercury vapor from amalgam fillings is absorbed by the body and can accumulate in organs, causing over 250 symptoms including neurological, kidney, and immune system damage. Mercury from amalgam fillings can cause chronic mercury poisoning, Alzheimer's disease, and other serious health conditions. There is no safe level of mercury exposure, and amalgam fillings pose a significant health risk.
Evidence / consensus	Major health agencies including the FDA, CDC, and WHO consider dental amalgam safe for adults and children over six. Studies have found little evidence that amalgam fillings cause health problems in the vast majority of people, and removing them does not improve health.

> OBSERVER NOTE:
A classic case of a plausible-sounding hazard that fails to hold up under epidemiological scrutiny. The mercury vapor release is real but minuscule, and decades of studies have not linked it to systemic disease.
