Transporting loads of foodstuffs and sugar snacks over pearly cobblestone mouth roads can result in potholes and bridge problems. Maintain your digestive highway with today's Groupon: for $29 you get a cleaning, exam, x-rays, and a take-home teeth-whitening kit at one of The Smile Generation's twenty San Diego-area locations (a $653 value). The Smile Generation's skilled professionals will keep your mouth's mountain ranges free of cavities and crevasses with a dental exam ($86), x-rays ($119), a cleaning ($85), and a take-home teeth-whitening kit ($363). The meticulous cleaning gives the heave-ho to any tartar and plaque buildup, clearing the way for future generations of inevitable meal remnants. You'll leave with a smile bright enough to melt hearts, including your own, so be careful around mirrors. Additionally, $5 will be donated to charity: water for every Groupon purchased.

Whitening is not recommended for children under 18 or women who may be pregnant.
