Recently had a crown put on top front tooth that had previous root canal, while the dentist was fitting it, he ground off part of the other top front tooth. He decided to put a crown on the other tooth. He prepared it and put a temp crown on. The one that is still alive, is extremely sore to pressure and can feel cold. It has a slight throbbing in it too. Went back told the dentist this, and thought it was bite. Anyways, he took temp crown off for permanent crown, and I about hit the roof. The took was EXTREMELY sensitive to the air, touch, you name it. He had to numb me for the permanent crown. turns out the permanent crown didn't fit right, so Had to be fitted for temp again. Now I am going on 3 weeks with temporary crown on and pressure pain and slight throbbing of the tooth. Is it possible that my tooth will not recover after being filed down for a crown? The tooth was perfectly fine until it was prepped for a crown. I have highly sensitive teeth, I have undergone 3 root canals already and suffer from TMJ. I am leary of getting the permanent crown on if my tooth does not quit hurting even though he said he can go through the back and do a root canal. what are my options? Thank you.
