When I was 16 I had an expander placed in the roof of my mouth followed by braces. I am currently 22 and my teeth have begun shifting again. I have a minor crossbite on both sides of my jaw along the entire jaw line (front to back). I've also recently been having slight clicking in my jaw (possibly TMJ). Obviously, my expander did not do it's job when I was 16, and I'm now not sure how to correct my bite and, subsequently, the slight crowding of my top teeth again. Should I approach a new Orthodontist or go right to an oral surgeon to get the bite taken care of?
