I had a root canal on tooth 30, 21 months ago. I have been told that I have Traumatic Nerve Injury to the v3 branch from the Local.  I have tried all the meds out there.  I have a RFL which a numbed what the neurosurgeon thought it would, but my major complain of fierce burning and throbbing in my gums on the the right side is still there.  I did feel a horrible sharp pain through my gums and tongue when the root canal was being done( enough to make me "Tap out"  and I cried the rest of the procedure.  I have been to 2 oral surgeons. Ant thoughts?
Hello there, Thanks for writing your query, Any injury to the nerve branches during dental procedure takes a little longer time to heal. The nerve fibers regenerate with a course of time and the symptoms will subside. Burning sensation and pain in the gums can be due to other gum problems, I would suggest you to get the examination done consulting a dentist. Exact diagnosis can be made only after clinical examination and evaluation by taking radiographs.  I would suggest you to get and OPG radiograph done which will help in diagnosis and accordingly treatment can be planned. Consult an oral surgeon and get the examination done.  I hope this helps, take care.
