Please. Dr. Weil. Stop.
In June 2008, the FDA settled a lawsuit with some consumer groups by agreeing to warn the public about the potential health risks posed by mercury from amalgam fillings, even though no new evidence has emerged linking the amalgam fillings to health problems. While there is no question that mercury vapor is toxic, its release from amalgam fillings is very slow, and I’m not aware of any studies here or abroad showing that it presents a health risk. Most release occurs when fillings are put in, making it more hazardous for the dentists who work with amalgam regularly than for the patients whose teeth are being filled. The only documented problems that have been traced to the fillings are rare, local side effects or allergic reactions. [emphasis added]
For Dr. Weil – the above is from the Q & A area of his website – and others who are “not aware of any studies here or abroad showing that [mercury in fillings] presents a health risk,” please see this and this and this and this and this and this and this and this…just for a start.
