I am 192 cm tall (about 6'3) and I think I could be pretty handsome, if it weren't for one thing, my teeth!

They are just so awful! My dentist told me a while ago that I will always have glitches, since I have much space in relation to my teeth, in my mouth. They can get straighter with a brace though, but I thought it wasn't worth it. I am starting to regret this now, so maybe I should let my dentist know that I've changed my mind about it. But I want other information, do you know good "dentist sites"?

Also, do you know if there is such a product, where you can have like "painted teeth" lines, that you can paste over your real teeth lines?
