Hi I recently had a root canal performed about a week ago. I had trouble getting numb and had to have 7 shots of novacaine to the affected area. The last two shots, my heart was racing and it really freaked me out because I got super light headed, and I could feel just about everything they were doing after. I started experiencing excruciating pain directly after the root canal finished and up until now. I went to an endodontist and he said the root canal is incomplete, and she didn't go all the way to the root in both canals, and that I would have to go back to get it redone. I am so scared, and even though they are an expert, I really don't want them to hurt me. Do you think that it will hurt to have this process done all over again, and I'm a little scared because of the heart problems i had when responding to anesthesia . Is there any way around the reaction to the epi?
