"I can't smile without you..." "Whenever I see your smiling face I have to smile myself..." Barry and James sang it perfectly in the '70's when they topped the charts with these hits. It's about time we realize that if you are going to have Donna Karan envelop you in her cashmere, Frederic Fekkai tease your tresses and Radu firm up your form, then someone should also fashion your smile. Enter Dr. Marc Lowenberg and Dr. Gregg Lituchy, two Manhattan-based dentists with a rolodex that gossip columnist Liz Smith would kill to get her hands on.

Within the confines of their exclusive Central Park South office dentistry has become artistry and those in the know fight tooth and nail for an appointment. These are no ordinary dentists.

Dr. Lowenberg and Dr. Lituchy are cosmetic dentists who are at the forefront of an aesthetic revolution. They have built a practice on the premise that a smile makeover can illuminate a face so much so, that it will render a more youthful appearance.

"Most people don't realize that the smile actually shows age sooner than any other facial feature," explains Dr. Lituchy. "Through the use of laminate veneers, a tiny porcelain facade that is bonded to the tooth, we can change the shape of the smile and bring the color of the teeth back to the way it was when you were 20," adds Dr. Lowenberg.
