What causes unbearable pain after root canal treatment?
Patient: I had root canal treatmentent filling last Tuesday and yesterday went back to have a permanent filling in the root canal.  It took the dentist an age to do it and it was quite painful.  Since then the pain is unbearable worse than before the treatment. Advice please Doctor: Thanks for posting your query to HCM.After going through your history, high point on the permanent restoration seems to be possible cause of pain.Please visit a dentist and get the high point reduced.Hope my answer will help you.
