Hi,My teeth are all straight except that I have a overbite,and a gap in my front two teeth(I used to suck my thumb when I was little)I went to a dentist and he told me I would get a retainer to pull the front teeth together and move them inwards to get rid of the overbite and spacing,But the issue I have is that the underbite causes my face to look shorter,when I move my lower jaw outwards to get closer to my upper teeth my face looks much better,Does an overbite mean that my jaw are not align correctly?I d like to know if braces can actually move my lower jaw outward rather than moving my upper teeth inward or is there any other option that can do that, Im a 20 year old female am I too old to have my jaw align since I dont think its growing anymore?
