Hmmm, a tooth extraction. I have seena chart once where every tooth was related to a certain organ or part of the body. That's something worth looking into. I wonder if placing any type of filling on any tooth results in the related organ to become weak, or diseased, in addition to mercury poisoning. The whole fillings thing is a joke. When I had a diet change, all my cavities healed. Teeth heal, and to place even composite fillings on them will probably lead to problems.

Also, what about the mercury you said you ingested? If so, the body would stop allowing chelation because it would only make your situation worse, harvesting mercury and redistributing it back into the brain. Something like that.
