I really like the theory about food being pushed out through the teeth. I have been watching my teeth and they are not static, solid rocks. My teeth seem to change shape and color, mostly on the biting surface. I have personally seen a small carrie form and then dissapear.
Anyways, This topic hits home with me. I have a mouth full of Amalgam surfaces and the mercury is driving me crazy!
I really want the amalgam out, and replace filings with nothing, just have big holes in the teeth. Would the teeth dry out? If I was living against nature I doubt this would work, but if I was living with nature I think I got a shot.
