Hi everyone..just curious if anyone has experienced TMJ before and what happened? These past two or so weeks my jaw has been popping every time I open my mouth, and sometimes gets "locked" at night. My cousin is a dentist, and has already made me one mouth guard that did not work at all. He just made me a new mouth guard that I started wearing two nights ago. I've seen a small improvement, but my mouth still gets locked up at night. Has anyone experienced this? I'm looking for a little hope and hoping someone has been through similar and has seen improvement. As of now, I have no jaw pain or headaches, like I've heard other ppl with TMJ experience, but I'm afraid that is the next thing that will start to happen.
