Teeth, like shirts, can be made from a variety of materials and are bound to acquire stains when presented with a water balloon filled with wine. Clear the temptation history of your mouth with today's Groupon: for $199, you get a Zoom! teeth-whitening treatment from Mindy Thompson, DDS.

Mindy Thompson and her dedicated staff wield the Zoom! whitening system to obliterate unconfident smiles. To launch mouth magic, a technician coats teeth with a stain-fighting gel and then focuses a specially designed light onto the chewing instruments. After the luminous beams activate the gel's brightening agents and render teeth up to 10 shades whiter, gummed pearls receive a fluoride treatment. Mindy suggests that patients pair the treatment, which takes about 60 minutes to complete, with gel trays (not included in this deal) to maximize their smiles' luminosity, longevity, and friend-making abilities.
