Q. I used to have an underbite, however, followinglower maxiofacial surgery, that was corrected. My upper jaw is still relatively smallin comparision, and my bite is close. When I smile I show alot of my bottom teeth, including gum exposure. They have slight crowding also. Would it be possible to lengthen my top teeth and widen the appearence of my upper jaw with minimal invasion? also what can be done for my bottom jaw, I had fixed braces to relign before and they’ve moved bak to their overcrowded position. I do find it distressing as I’m getting married in August and have had treatment since iwas 11 but it’s still not right or a normal smile.
