See a dentist and a specialist who can x-ray your teeth and make sure you have no cracks. My neuralgia was immediately controlled when my tooth broke. Evidently hairline cracks in your teeth apply pressure to the nerves which result in the pressure and headaches. It was the most horrible pain in the world. I don’t know what I would’ve done if my wisdom tooth didn’t break after four months. I took the opioid. I had on hand for my degenerative disc condition for the ON pain. The dentist told me that hairline cracks in your teeth can go unnoticed on the x-rays.Good luck.
