A glowing smile charms irritable librarians, stern highway-patrol officers, and judges with highfalutin ideas about driving through the library. Flaunt your beaming beauty with today's Groupon: for $79, you get a teeth-whitening treatment at Laser Light & Sound (a $222.88 value, including HST), redeemable at its four locations in Victoria, Qualicum Beach, Courtenay, and Nanaimo.

In just 30 minutes, the smile technicians at Laser Light & Sound lure out dazzling chompers hiding just beneath dingy exteriors with a professional teeth whitening. The treatment immerses jaw pearls in a flexible mouth tray filled with whitening gel, then shines an LED spotlight on them, activating the whitening process and setting the stage for dramatic molar monologues. After the single treatment, clients can flash a smile between two and eight shades whiter, with results lasting up to a year with weekly maintenance, such as a touch-up pen (not included in this Groupon), though stubborn nicotine and Rorschach stains may require a second visit.
