You have been through so much. I have cried at the dentist too, so don't feel bad about that. Please post to Bryanna. She has 30 years experience and is around the dental site postings. You need of course to see a specialist who not only knows dentistry but TN. It is my understanding that denerving a tooth is the same thing as a root canal. These root canals can and do cause trouble. Keep coming back, More postings will come up about your situation. Do seek out This dear lady, as she has helped alot of people on neuro talk with some pretty difficult situations. You can also post to her private if you want to. I trust her advice Maisie, and feel she would be the most knowledgeable on the dentist issues on this site. I hope that you can find a resolution to your pain, and that the TN is address in a way that it is not agrivated by further complications. Be good to yourself. ginnie
