In the 1970's, a friend of his who is a physician and who treated the Rolling Stones sent Ron Wood and Keith Richards his way. He has been treating dentally underprivileged celebrities ever since.

Ann Marie Cseh, a Hungarian model, provided the startling before-and-after shots gracing the outside of the Lowenberg-Lituchy press kit and video. Eastern Europeans have supplied an influx of candidates for their services, as have rap and hip-hop stars, many of them sent by the music impresario Russell Simmons, himself a patient of Dr. Lowenberg. On the wall of fame is a signed, framed cover of the February issue of Vibe, featuring Foxy Brown, a rap star.

"Half my practice is in this magazine and I have no idea who these people are," Dr. Lowenberg exclaimed, sounding stunned that famous people exist who are unknown to him.

Sy Presten, the practice's press agent, turns some of those famous names into gossip items. But such is the status of the celebrity dentist that details of Dr. Lowenberg's personal life made the papers when, a year ago, he started dating a patient, Joan Finkelstein, a former owner of the New York Law Review.
