A 43-year-old member asked:

Is there enough mercury in a tooth filling to do you a lot of harm if swallowed?

Probably no: When i remove amalgam fillings I use the mercury-safe protocols latex-free rubber dam protection, specialized high speed suction and have an amalgam separator to prevent mercury amalgam from entering the city water system. The problem with mercury fillings is the constant release of mercury vapor which occurs with vigorous chewing, tooth brushing or clenching and grinding of your teeth.

No: There is very little mercury in amalgam fillings. The material becomes a stable alloy after setting hard(fda studies). Swallowing some silver filling would not likely cause any harm and would pass through your system. The only concern would be an allergy to metals.

55% mercury: Most amalgam fillings are 55% mercury. How much didi you swallow? The most harm comes form mercury vapor which easily ionizes and caused damage to your systems. Predominantly brain, kidney and lung. There are many ways to remove heavy metals form your body, chelation therapy is the most effective.
