I'm going backwards here as usual...Sorry. I think teeth are always sensitive for a while after you get fillings redone or done at all. I use to have to wear an NTI, too!! I didn't have any occlusal! Of course grinding those already sore teeth isn't going to help. Something about mercury causes grinding but don't know why??? A nervous system thing somehow. Sorry...brain fuzz...but you aren't alone with that. I had a very similar experience, too, with an MD. I'd had my fillings out when I did a challenge test, but he gave me a bad protocol for chelating. Luckily I found Andy Cutler's website and he directed me to his book and forums before I actually used this guys directives.... I learned a lot being on those forums. This forum is not as restrictive, more social (which I like more for now). But lots of good info here with experienced folks, too. Welcome, but I'm sorry you are going through this. If I laid out every issue I've had or have most people wouldn't believe me.. but I'm relatively healthy for being so unhealthy!!! : ) I think most people just aren't aware what is going on, though, and we do.
