Last week I had root canals done on my front teeth. The dentist started an opening on all four. She was only able to remove 2 of the roots. The pain was so bad, I just couldn't take it anymore and I started to cry. I have a pretty high pain tolerance. She wanted to continue and told me that I was having this pain because I was nervous. And if I wasn't nervous I would not feel pain. She also asked me if I had any alcohol the night before. Which I did , one sip of my boyfriends margarita and that's it. I really wasn't nervous until I experienced the horrible pain in my nerves. I asked her if she could numb me more with shots. She tried again , I could not go on anymore. Now, I have temporary white fillings on all four. I am too scared to go back to her because I feel like she is not very experienced. I have had extractions done by another dentist and I was awake and didn't feel anything. So how come I felt so much pain during this? My question is have any other dentist heard of this kind of thing happening before? Could it be an infection or is she not experienced enough on root canal treatments. I didn't have any pain or abscess from these teeth. She also broke more of my tooth which is extremely noticeable now. I decided not to go back to her and scheduled another appointment with someone else. I am concerned about how fragile my teeth are now, because they can fracture easily . Any opinions or advice would be appreciated.
