My sister is having some jaw alignment/structure problem (like a protruding mouth not severe but mild although still it affects the appearance) I always ask her to consult with dentist for reason behind it and of course the solution as it mildly affects the appearance of her but she made her learn to live with that condition maybe she is scared about braces/surgery like things and time involve. Note: It's not giving any problem in eating breathing or other things just wanting to improve the appearance.
