Re: CONSTANT facial pain and headaches
My best advice would be to see a dentist and get xrays and an exam.
Ask him if you show signs of night grinding. you may want to look into a night guard regardless. If you're grinding at night and clenching during the day that can definitely cause headaches and facial pain. You could ask him to check you for TMJ as well.
I hope that grinding/clenching is your problem because that is a pretty easy fix.
It's weird b/c we have the same symptoms and seem to have tried all the same stuff. I grind at night but have worn a night guard for a while so that isn't my problem. and i don't clench during the day. I'm at a loss for myself.
Anyway, I hope that helps and that your problem gets resolved soon. Keep us posted!
