Say cheese! A bright set of pearly whites is of course a beauty must have, but teeth are really important in some areas of the US. In fact, it can be a relationship dealbreaker!

Real Self recently reported that a great smile is important to Americans - especially when it comes to dating. 

In a national survey recently conducted on behalf of, results confirm what we reported in our story on oral care and dating -- that when judging a potential date, both men and women rate teeth as the most important factor.

Helen Fisher, a research professor at Rutgers University who helped develop the survey, wasn't surprised that teeth came out on top. "From a Darwinian perspective, good teeth are a real indication of your health - how much you drink, smoke, what you're eating," she explained. 

It's clear that single Americans take their smiles very seriously. Can we blame them? There's just something about a great smile that's appealing, healthy-looking and super sexy!
