First, I doubt you'll need to be a millionaire to fix your problem with your teeth. I'm for sure but I've heard of wonderful payment plans for procedures like that.
Secondly, if a girl is judging that hard especially after learning more about you then she probably sucks and isn't worth the time.
Thirdly, as a woman, confidence is key. Don't let any woman know you feel bad about yourself. Fake it till you make it. If she gets to know you and doesn't like you for whatever reason that her fault, her loss.
To answer your question: I think most decent women just want a decent (inside) guy, so yes a woman will want you. :)
