On a serious note, I got a buddy from Spain. Well, he says he hates Spain, so I guess I gotta say he's from Catalonia, and he doesn't brush his teeth.
First time he told me I didn't believe him, cause he doesn't have a bad breath.
But yea...his wife confirmed it. Doesn't brush his teeth, and doesn't have any teeth problems. He doesn't eat sweets or fruits though, and also doesn't drink soda...he's more of a meat guy.
