The trigeminal nerve is one of the largest nerves in the head. It is responsible for sending messages to the brain from the face, jaw, gums, forehead and eye areas. The impulses sent have to do with touch, pain, pressure and temperature.
If the insulation of this nerve root is worn away by constant rubbing over time from blood vessels in the brain, then irritation to the nerve results.

- pain can be brought on by swallowing or brushing teeth
- pain often on one side of the head
