Opt for a laser treatment. The Zoom! laser whitening treatment can zap stains from teeth in as little as an hour. The painless procedure costs anywhere from $300 to $1,200, depending on the physician, location of the practice and varying equipment used during the application. Celebrities like Alicia Keys, Amanda Peet and Tyra Banks rely on Zoom! laser treatments to maintain a camera-ready smile on and off the red carpet.

Purchase an advanced whitening kit from your local pharmacy or discount store. From Colgate to Rembrant, many brand-name manufacturers offer at-home teeth whitening kits for as little as $10 dollars. These products vary from tray fillers to gel adhesive trips that are applied directly to the upper and lower arches. Most products guarantee a dramatic change in anywhere from 3 days to 2 weeks. Brooke Shields, a spokesmodel for Colgate, uses the product to keep her teeth healthy and her product in high demand, saying, “Having the perfect smile is a job requirement for me!”

Visit the Celebrity Sexy Teeth website to order Celebrity Sexy Teeth whitening products. Seen on E!, Extra!, OK!, Style and Oh! Oxygen, the product claims to whiten teeth up to eight shades in 14 days. Backed by a guarantee, the company promises, “No strips, no trays, no harsh lights, no drip, no mess!”

Buy a toothpaste whitener. This simple and fairly effective method is best when used with a companion mouth rinse. Results will vary, and may require longer processing times. To use, apply a dime-sized amount of the paste to a toothbrush and then brush teeth as usual. During a recent taping of the Conan O’Brien show, Halle Berry claimed that this technique keeps her teeth “extra clean” and “bright.”
