I was actually talking about this with a friend the other day. I guess it depends on what you mean by "bad" teeth. If you're talking discolored, yellow, fuzzy looking teeth then I completely agree with you; that's repulsive. But for me, a woman with some crowding can be extremely sexy. I'm not talking sabre tooth tiger, snaggletooth type stuff, but some crooked teeth with a little bit of crowding turns me on for sure. Kind of weird, I know. I think it has something to do with the fact that when you see an otherwise gorgeous woman with "imperfect" teeth, so to speak, it makes her that much more attractive because you can at least spot one flaw. Maybe it has something to do with viewing that woman as more approachable?
I don't really think I've done a good job explaining myself here, but it makes perfect sense in my head. Anyone understand what I'm getting at here? :dunno:
