My observation also is that if you go in to get your mercury out, yes you will get it out, but you will also end up with crowns/root canals, etc. I had NO root canals or crowns at all until they started digging out the mercury. Mary, Do you mean that the process of removing the mercury caused the need for root canals, etc? When Dr Katz filled my teeth, he never even discussed whether he was going to use mercury, composite or gold. I suppose I have mercury, since they are grey. (Is there another compound which is grey?) The mercury-filled teeth ache and "taste" like metal. I hate it. I would rather have gold, but not at the expense (I don't mean financial expense) of a root canal. Do most insurance companies pay for gold fillings, or only if medically necessary? I will have to check with my provider on that. Man, I hate this. I would rather have a pap smear (yikes!) than go to the dentist. I don't trust them. I certainly don't want my healthy wisdom teeth removed, I don't want to end up with headaches and neck pain for the rest of my life, or systemic infections in the jaw. My godmother went though an excruciating HELL for several months with a situation like this that was misdiagnosed several times before they found the infection. ("I told you so") I wish we had a "paleo-friendly" dentist here (on the list). Stacie
