If your eyes are the windows to your soul, your teeth are the white-picket-fence posts that protect the soul from oversized bites of taffy. Strengthen your defense against attacks on the soul with today's Groupon: for $104, you get a one-hour, in-office laser teeth-whitening treatment at Cara Bella Studio in Greenwood Village (a $325 value).

Cara Bella's licensed aestheticians treat tarnished teeth to three gentle, 20-minute laser blasts in one office visit, emboldening enamel with the same cold-light whitening technology used in professional dental offices. After the pain-free polishing, your pearly chompers will triumphantly pop from vacation photos, help you attract new square-dancing partners, and stun awkward relatives into admiring silence with their brilliance. Results from your personalized treatment typically last up to two years, and the safe, light-activated whitening gel improves bicuspid brilliance an average of eight shades. If grimy Darjeeling residue accumulated throughout the years has resulted in an absence of happy, open-mouthed activities such as eating, laughing, smiling, and stage heckling, this treatment will restore confidence and permanently pause your pursed-lipped lifestyle.
