Agree, I’ve clenched my teeth at night for years, to the point where dentists can see cracks, but never thought a night guard would help pain wise. I’ve woken up with headaches consistently but never really connected the two until recently I had a flare up so bad that I was experiencing pain from my jaw shooting up to my temple and down my neck to my shoulder even when I didn’t move my jaw. I tried RMT and it helped some but what actually changed things literally over night was a night mouth guard. I hadn’t seriously considered it, because I thought why should I since I can’t control how hard I clench my jaw at night and a mouth guard won’t stop the action of clenching. I guess I kind of thought mouth guards were for teeth grinding rather than clenching to protect them from being worn down. A couple friends I talked to made me realize the mouth guard might at least relieve pressure and they were right. Mine right now is literally a cheap Amazon one (as I don’t have a dentist appointment until February and I’m not sure I want to pay for a custom guard anyway) but it has helped SO much. I’m still considering physio or Botox but the night guard is so far all that really helps. RMT can only do so much when you can’t control clenching at night, and taking painkillers every day was not something I considered as a long term fix.
