Will braces make my face/jaw smaller? (Photos)

I have an overbite with my top teeth which are pretty straight. My bottom teeth have a little bit of crowding but my orthodontist said I won't need braces for long,9-12 mo max. My molers all line togther when I bite back but my front teeth Stick out a bit. I always just bring my lower jaw forward which makes my face appear longer and I think it looks pretty good like this but I'm concerned if I get braces will my face/jaw appear smaller ?
