59 year old white female, 5ft 2in, 145lbs... good general medical condition.8 months ago I had a rood canal of an upper molar... the next day I suffered a severe Bells Palsy of the facial nerve on the same side, which has not fully recovered.  I now need another root canal on the same tooth, but am terrified of the procedure as I am not sure if the Palsy is related to the original root canal.  Should I be concerned?
Thanks for your query, I have gone through your query. The bells palsy could not be because of the root canal treatment. But it can be because of the nerve injury during local anesthesia administration. You can get the root canal treatment but follow a proper injection technique. The palsy might reverse back to normal in days to week. You can take nerve regenerating Chat Doctor.  I hope my answer will help you, take care.
