A session with teeth-whitening pioneers BriteSmile usually costs about $600. If you wait for a sale, you might only pay $350, or $300 once in a blue moon. Today, we’re pleased to bring one of our most popular Chicago deals to Atlanta: teeth whitening for only $185. That's 69% off! We know $185 is a chunk of change, but for what you're getting, nothing comes close. If you've ever considered teeth whitening, get today's Groupon, and head to Phipps Plaza at 3500 Peach Tree Rd., NE—you'll save hundreds of dollars.

BriteSmile's patented stain-busting technique involves UV technology and fancy lamps that shine gentle blue light all over your teeth to whiten them. As they work, you can go nappy-nap, watch TV, fantasize about future Groupons, or just relax. When the hour's up, your teeth will be in factory-new condition; customers have seen their teeth get up to 14 shades lighter. Your smile will dazzle your boss, significant other(s), prospective job interviewers, and anyone else you want to impress. Already had your teeth whitened? Email friends who need to keep their smile looking good for professional reasons (salespeople, politicians, Marlboro spokespeople, teeth models, etc.) so they move up the ladder.

Aside from the obvious benefits of teeth whitening—professional advancement, increased sex appeal, etc.— there are lesser-known practical pluses. For example, if you and your partner each get a treatment, you'll not only look better for each other, but you can use each other's teeth as mirrors when you need to comb your eyebrows on the go. If you ever lose a post-whitened tooth, you can find an African ivory poacher and trade it for pure gold. This Groupon also makes an excellent gift for a loved one with disgusting teeth. If you've been slacking on maintaining your basset hound's dental hygiene, make up for it by giving him the gift of teeth whitening: he’ll be happy anyway and you can attribute his joy to your generosity.

Don't be fooled by laser-whitening treatments you see listed for $199. They won't get your teeth nearly as white as BriteSmile (eight shades vs. BriteSmile's 10–14 shades) nor will they last as long (six months vs. BriteSmile's one–two YEARS). Those are scams run by evil doctors who live for the thrill of shooting unsuspecting patients in the mouth with real lasers! A manicure might last you a week. A wax? Maybe two. But a BriteSmile teeth-whitening treatment will take you well past the year Back to the Future 2 was supposed to take place. Get your Groupon!

Note: Don't forget to mention your Groupon number when booking your appointment.
