I've had this for a very long time and i'm wondering if it's normal for your jaw to pop when you open your mouth all the way? It happens whenever I yawn, eat big foods like hot dogs, or when I just open it wide for like the dentist or something. It hurts if it's kept open wide for a long time, that's why I hate the dentist so much. Is there some problem or does this just happen because I have a small mouth.
