Think movie stars were born with perfect smiles? Two New York dentists say think again.

To the rest of the world, Tom Cruise has one of the most beautiful smiles imaginable. To cosmetic dentists Marc Lowenberg and Gregg Lituchy, the guy's a mess. "Check him out," says Lowenberg, pointing to a typically stunning picture of the movie star. "He's got a crooked lateral and his midline is totally off."

Whoa.

If it weren't for the pronouncements that come directly after that, a visit with these two would be even more excruciatingly painful that the usual trip to the dentist. But just when you're tempted to slit your wrists, Lowenberg rushes to the rescue. "Let's face it, it certainly hasn't hindered his appearance in any way," He says of Cruise's slightly wayward upper tooth. "Sometimes imperfection is perfection for that particular face."

As unofficial "dentists to the stars," Lowenberg and Lituchy have seen many a famous molar in their day. And in the deep recesses of their Central Park South practice, in a tiny office on the second floor, there exists a veritable shrine to their expertise. Sitcom stars past and present, models, rock stars—they're all there, beaming out from a sea of autographed headshots and glassy magazine covers.
