Could jaw clenching/grinding be related to the mercury amalgams? I am noticing so much clenching lately, and I feel like I cannot relax my jaw. I am noticing more metallic taste in my mouth. Is there any evidence that these are connected? I am nursing a newborn, so I am a good 4-5 years out before I can get my fillings pulled and chelate, which is a very helpless feeling. The idea that my mouth is poisoning me and I can't do anything about it really rankles me; trying to figure out how to manage it for the next several years into I can do extraction.
