If that doesn't stretch it you can spread the two fingers apart or try 3 fingers. Do that 10 times when you feel your jaw tightening up, at bedtime and in the mornings if you suffer from waking headaches. Make sure it isn't your teeth or an ear infection though. They can make a bite guard that goes over your front teeth that keeps your teeth apart a little, that usually works wonders. If it sounds like that may be it, try the home stuff first.
Bite guards are expensive and it is difficult to get an insurance company to cover the cost of one.
The surgery worked for me but I wouldn't recommend it to anyone unless they could no longer bear the pain. I hope you feel better. All rights reserved.
