TMJ Help Site

I have just recently been diagnosed with TMJ. No nausea or light headedness, just some cracking, popping and occasional pain. My doctor mentioned that it may be caused by night time teeth grinding (which i have been told by my dentist that i do) and i might want to look into getting a night guard mouthpiece. But when i opened the box, it said it was not recommended with people who have TMJ. But doesnt explain why. I want to stop the nighttime grinding, but i dont want to make my TMJ worse.
Any help would be greatly appreciated.
(He just prescribed me an NSAID (Naproxen), some muscle exercises and recommened i use ice packs which i have been)

I have a bad case of TMJ and need a night guard for my mouth. I’ve been told I grind my teeth at night. I purchased a mouth guard from rite aid a year or two ago and it hasn’t helped. it was only 30.00 and it’s one of those ones you boil and it would move around in my mouth and wake me up it never helped. so whats a good mouthguard to use at night time that i can buy? I need something that will fit my teeth without moving, and something that isn’t like OVERLY expensive and will last a good bit to help with my grinding and TMJ?
