Just recently while having dinner I casually made the observation that I can only 'pop' the left side of my jaw now that I've had braces. Beforehand, I could 'pop' both.
My mom asked me to show her what I meant, so I did.
She says I am dislocating my jaw, and classified it as TMJ.
Naturally I was concerned, and looked into treatments/exercises for TMJ.
But the more I read, the less I could find that actually related to my situation.

The cases of TMJ I've read about are often associated with pain or discomfort, and cases of dislocation are often by accident, and are quite noticeable.
For myself, however, I can dislocate my left side whenever I want, simply by opening my mouth wider than normal. When I close my mouth, it returns to normal.

I'm curious as to what I should do concerning this, and if there are any specific exercises to 'fix' what my jaw is doing, as my mom claims. She says that she had a similar problem, but it was after a car accident, and doing the exercises helped put her jaw back in place. But I'm not sure if she had exactly what I have.
Again, I'm not experiencing any pain, I've just always been able to do it, for some reason now only on one side.
