I had braces in junior high, but failed to consistently wear my retainer, so.......
...... I looked into Invisalign a few years ago, and the orthodontist told me they wouldn't work on my overbite. He said I'd need to have my jaw broken and reset, and that's the only way my teeth would ever stay perfectly straight.

I got a second opinion-- same thing.
Needless to say, while I'll never have a movie star smile, I've decided mine's really not all that bad.
