Celebrity dentist Marc Lowenberg and Gregg Lituchy keep the celebrity set's million-dollar smiles sparkling.

Dentists Marc Lowenberg and Gregg Lituchy display the requisite number of wrinkled magazines in their Manhattan waiting room. What perhaps makes their Central Park South digs unique is the professional masseuse doling out backrubs.

Appropriately enough the two dentist who call this state-of-the-art office home hover at the cutting of their craft. In a world where fluoride and flossing have reduced the numbers of tooth decay, the pair can focus almost exclusively on cosmetic dentistry, the procedure of making teeth whiter, straighter and generally more perfect.

These upgrades predictably attract an A-list roster of patients that reads like a celebrity Who's Who—Cindy Crawford, Jason Patric, Russell Simmons, Paul Reiser, Foxy Brown, Kevin Spacey and Christy Turlington, to name a few. And the job comes with a few perks. Besides being entrusted to maintain the beauty of these glamorous faces, Lowenberg and Lituchy get the hob nob with the haute-monde. Actor-patient Ron Eldard recently took Lowenberg to his off-Broadway phenom "Bash," for example. And musician-patient Mary Travers of '60s folk trio Peter, Paul and Mary was his Southampton houseguest last weekend.
