Hi Russ, thanks for getting back to me. There are no lesions or spots or anything. The weird thing is the burning is on the side of my problematic dental work. I have amalgam on the top and gold on the bottom. My holistic dentist thinks it is the galvanization between the dissimilar metals causing the burning. I hope he is right. He is taking off the gold crown in two weeks and replacing it with porcelain. I hope it helps. I don't think I can handle this pain for two more weeks!!
