What is dental nerve injury pain?

Rarely, a nerve in the mouth may be injured during a dental procedure, like a tooth extraction or a root canal.  This leads to the immediate onset of a constant, burning, or aching pain in the distribution of the trigeminal nerve supplying that tooth, including the face.  There is often some numbness.

This is NOT trigeminal neuralgia.  It is rarely relieved by the medications, like carbamazepine, that are so effective for trigeminal neuralgia.  This type of pain is NOT treatable with neurosurgical procedures like microvascular decompression, radio frequency lesion, or radiosurgery.  Nerve burning procedures, like RFL, may actually make this kind of pain worse!

Oral surgeons may be able to help.  Otherwise, pain management is the best option.
