A member asked:

Does overusing the masseter muscle change the jaw bone shape or jaw appearance? does it change the jaw bone making it less curve? please be specific.

No: The shape of the jaw bone is determined by genetics and early function. The masseter (cheek) muscle may grow from overuse and affect the width of the face. You might only notice this in very lean persons.
