Q.
My dentist says I need some root canal work on a tooth that aches when I eat. She had drilled out the decay, nearly down to the root, but it still hurts, hence the root canal work. I had 1 injection for the filling, but I still nearly had to ask her to stop, as the pain was so bad. (My last dentist used to give me 2 injections for a filling, & it still used to hurt). I really dislike the idea of root canal work, can the tooth really be numbed enough for this work to take place? Any help would be much appreciated.
