I have TMJ too, Dawn. And have ground my teeth for years. It wakes me up, too. I wore braces (in my 40s!!!) a couple years ago so now wear a splint at night to hold my front teeth in place correctly, but use to wear a rubber one which helped. I wore mine down really badly partly due to my bite...but still grind and wake up very sore at times. Causes head aches, too. Lots of head and facial tension.
