Q. I’m nineteen and I was wondering if Invisalign would work for me. As well as overcrowding on both the top and bottom (particularily the top, there is quite a bit of overlapping), I also have an overbite. If I clamp my teeth together, the top row covers the bottom. If I push my jaw forward and do the same thing so that they’re even, only the two front teeth touch the bottom. The rest of my teeth don’t touch at all. Can Invisalign help correct an overbite like this? I can’t stand the thought of having to wear metal braces. I’ve read about jaw surgery as well but I don’t know how that works and what the result would be.
