To Mole or Not To Mole? That Is the Question

One of my good friends recently got braces to correct a slight gap in his front teeth. When I saw the braces the first thing I asked was, "Why would you do that?" From my perspective, I've always found his flawed smile an endearing and signature part of his character (similar to how I feel about Lauren Hutton's or Madonna's tooth-gap).

It goes without saying that I feel similarly about Sarah Jessica Parker's chin mole, which she just had removed for cosmetic and not medical reasons. I'm all for freedom of choice, but if she were a friend of mine, I'd have told her to rock that mole indefinitely. Where do you stand on the issue? Are small flaws beautiful or would you "fix" them too?
