When my wife had Trigeminal neuralgia it was caused by blood vessels tented up against the fifth cranial nerve that runs down the jaw. The vessels that were tented up were in the brain. Took several years to figure out problem. At first idea was that it was caused by teeth. She was ready to have all teeth removed when she sat in the chair of a dentist that said you have come to the right place. It is not a tooth problem. Glad you are improving. Her problem came and went for about 5 years. It has been 20 plus years now since she was cured. It gave her, her life back.
