Fwiw, here's some info on how people throughout the ages and in different cultures have considered gap teeth:

"...Over the years I've heard different stories and tales about this trait: A gap in your teeth is the sign of Venus - the goddess of love! I've been told. Being gap-toothed was regarded as a sign of a strongly-sexed nature in the Middle Ages as told in The Wife of Bath's Prologue and Tale from "The Canterbury Tales" by Geoffrey Chaucer. In some African tribes having a gap in your front teeth was a sign of wisdom and in France they call it "les dents du bonheur" (teeth of happiness)! There was even a film made by Les Blank in 1987 called Gap-Toothed Women, which explores different connotations of gap-teeth such as a beauty mark or as a sign of an amorous nature.

I've also heard that it's a sign of wealth, now, I don't know about that one! but, perhaps if we could ask some well known and not so well known gap-toothed celebrities they would agree."

The good thing about not using only one standard of physical beauty is that folks don't have to agree on what constitutes beauty.
