A smile makeover usually takes two visits that last a few hours each, so any of-the-moment cosmetic dentist's office has VCRs and stereos to keep its patients entertained. Marc Lowenberg and Gregg Lituchy also provide patients with laptops so they can work and check e-mails, and there's a massage therapist on the premises to make the whole experiece less stressful. Not everyone can afford a full set of veneers, so the doctors, who have been in practice together for twenty years, offer smile makeovers that combine veneers with bonding and bleaching, and they demonstrate what your smile will look like using composite materials on top of your existing teeth, a more accurate picture than the usual computer imaging. Courtney Cox Arquette, Cindy Crawford, Heidi Klum, Russell Simmons, Chris Rock, Marc Anthony, Sarah Michelle Gellar, and Narciso Rodriguez are among their clients.
