I have a good bite, with the possible exception (it's hard to tell) of an overbite (not overjet, I know people often get this wrong), but I have a very small and narrow lower jaw as well as a narrow upper jaw.
When I open my mouth very wide (wider than when I eat or talk) I hear a sound in my TMJ, but I don't know if it is the popping or clicking people usually describe.
I'm 21.
Do you think I have or am at risk of developing TMJ problems? I would like to expand my jaws for cosmetic reasons, do you think this would help or hurt any potential TMJ problems?
