I have had this problem for years, and see a great orthodontist for a mouth guard. If you can afford to have one custom made, it will work a lot better. After doing some research, one of the main causes of clenching at night is sleep apnea. I had a sleep study, and sure enough I have apnea. Using the CPAP machine has made a huge difference in reducing the night time clenching. I only clench now when I am under more stress than usual. Good luck!

I have gone for myofascial release treatments for pelvic pain and it helped my allergies.

I clench and grind my teeth at night and have tmj.

Long story short, ice helps for short term, also while alone, open your mouth and stay asking as you can that way to relax the muscles in your mouth and face and jaw. Try once or twice a day if you can. Last, I triedmyofascial release on my facial muscles. It is helping a lot- to relieve pain in teeth, jaw, head.

All you do is look for knots in your cheeks and when you feel tenderness or pain. Press gently no more than a level 3 out of ten. I use index and middle finger. Hold for 60-90 seconds. Look for another knot and do more. Also I will wash my hands and open my mouth. Use thumbin inside of cheek and index finger on the outside of cheek gently press together and pull outwards, beginning at the back of your mouth and finishing at the corner of your mouth edge.

You might find tons of muscle knots to work on. When you find one go back to the center of the knot and stay there for 60-90 seconds.

I had no idea all my muscles are so screwed up, knots everywhere prevent body from working properly and cause pain.

I hope this can help. You can probably get a medical referral but I wanted to do it myself and use my medical visits for my pelvic pains.

Work on the trigger points in your face and jaw, also massage tissue etc. Try voltaren or lidocaine to relax the area. Relaxation vids on youtube might help. Hypnotherapy.

Yes, have broken many teeth. I think my dentist likes me. Haha. I now have a bite reducer which I wear every night and that has helped a great deal. It seems to have helped re-align my teeth/jaw and find I don't do it so much during the day now. It has also helped my temporal mandible join disfunction.

Yes I have also cracked my teeth! The mouth gaurd shouldnt make u gag. It does create extra saliva in ur mouth which can b annoying, n hard to take a drink with it in. But worth a try.
Good Luck!
