My dentist made me a night guard for my bruxism. The problem is, it seems like since she's adjusted it last my jaw and tongue are so tight and I have a horrible constant headache in my face/temples/forehead. I am not talking clearly because I can't open my jaw like normal. It hurts so bad. Is it possible that the night guard is causing me to clench down even harder and therefore my jaw muscles are even tighter? I catch myself waking up in the middle of the night from biting down on my guard. Help please I am in so much pain from this. Should I quit wearing the guard until I can see the dentist??
