I had braces and I'm really slack with wearing my plate, but when I do put it in (maybe one night a week...or 2) it always fits fine but now I better wear it more often! If your teeth are making you self-conscious then definitely get them corrected. My mum recently started using invisline(sp?) the "clear braces" which are basically just plates and they work really well. She had braces when she was a teen but then her wisdom teeth came along and shifted all her straight teeth and now in her 40's she's decided to correct them again. So I say go for it!
