Is numbness in mouth and tongue after a root canal normal?
Patient: I had a filling re-filled in my lower right molar yesterday morning and am still experiencing mouth and tongue numbness on that side of my mouth, 30+ hours later.  The dentist told me I would experience prolonged numbness, but this seems extreme.  I've put a call into the office, but haven't heard back after 3 hours.  Is this normal, or could there be a possibility there is some nerve damage? Doctor: Hi..Welcome to HEALTHCARE MAGIC.I have gone through your query and can understand your concerns..As per your complain as you have numbness of mouth and tongue even after 30+. Hours it is definitely abnormal as the numbness due to dental anaesthesia generally resolves in about 2 to 3  hours at a max..It can be due to needle prick injury to the nerve that is leading to prolonged numbness..Many times mild injuries tend to resolve soon and the numbness may stat subsiding in next 2. To 3 days..But in case if it still does not improve consult a Neurophysician and get evaluated..As of now take Vitamin B complex supplements and do alternate warm and cool compresses..Hope this information helps..Thanks and regards.Dr.Honey Nandwani Arora..
