Tooth Answers

I clench my teeth at night. Sometimes it’s so bad that I wake up with tension pain in my jaw & neck & I can’t seem to fully relax my jaw. I know that a mouth guard is one option to protect my teeth, but that is a last resort for me because, 1. I can’t afford it right now & insurance won’t cover it, and, 2. It won’t really fix the clenching problem. So is there anything that you have tried to reduce teeth clenching that has worked pretty well?
