I recently had 11 of my teeth extracted since there were only 17 left. The top is all gone now after years of many thousands $ put in them. None of my teeth were rotten per se but had been worked on extensively and just weren't contrubuting to optimal health. The resulting "soft diet" and banishment of bad bacteria crashed my blood pressure. I only use 1/4 of my regular BP medicine now. I also feel a lot better mentally and emotionally. Sorry...no comments on Ammonia smell.
