Well, amalgam poisoning is hard to proove, as you can only test for it when your body is actually excreting it. I even know someone who did the DMSA challenge, and her results were over 300 percent over what's concidered normal. But the doctor said that that was fine, referring to data from the 1980s.

Also, if amalgam poisoning is really responsible for a lot of diseases, it means the dental associations and governments are responsible for thousands of deaths. However, sweden and germany have banned and are even helping people detox.

And, as already said, some people seem fine with amalgam fillings, for the time being anyway, so perhaps it just affects people with naturally low immune systems? And some people don't even realise IBS, cronic fatigue syndrom, [insert incureable disease here] are often due to amalgam poisoning.
