Welcome to PC! This is a good place to learn more about yourself. Glad you found us. There are other medications out there that might help you if you can just get to the doctor. And have you told your dentist this? I was an assistant for a dentist for a long time and we would give our patients something if they were extremely nervous. You have been on medication before so you know it can get better. I suggest you just go for it. We are here for ya.
