I have verry narrow upper arch (as seen on photo), narrow smile that is just getting more narrower by year, I also have difficulty breathing and posture problems. I did alot of research lately and saw that there was successful stories of palatal expander for adults but I also saw people talking about DNA appliance. My orthodontist told me surgery in my situation would be best, and also invisalign or braces to slightly tilt my teeth but that cannot expand my arch. I would really want a second opinion
