I don't see why not, I like quirky smiles. 'Perfect' teeth aren't as interesting to me. I had an overbite and teeth not totally straight, then I had braces for two years. When I got them off, my teeth were perfect. But at some point I lost my retainers, so my teeth ended up shifting back a bit. They're at a halfway point between my before and after braces, and honestly I much prefer my smile like this. It's more interesting, more me.
Yes, I actually prefer when guys have little overbite. It look so hot. I mean, look at Alexander Skarsgård, he's so hot. My first crush had a little overbite, and the first guy I was in love with had overbite, and the first guy I ever had sex with had overbite. All different guys. I love an overbite.
Depends on how bad it is. Is it an slight overbite or severe to the point where you have difficulty closing your mouth until your lips meet. I
have a slight overbite, and I hate it. Though I must say that other than the overbite my teeth are perfectly straight and white with no gaps. Most people don't seem to notice my overbite and the people who do notice think it's cute!
