I find her to be cute, and maybe even a little sexy, but when she smiles and you see those teeth, it is a definite minus.
I think if she got her teeth fixed it would take her from a 6 to an 8.
Bad teeth can make even attractive people a turn-off. And this is more true for women than it is for men.
Lay off on the teeth. She has a gap. Big deal. I'll bet she keeps them as a symbol of her upward mobility.
