Though steel teeth may be less likely to develop cavities, they make airport security lines and magnet eating nearly impossible to enjoy. Nurture the grill you were given with today’s Groupon: for $149, you get an in-office laser teeth whitening and paraffin hand treatment at Landmark Dental Studio in Greenwood Village (a $450 value).

Landmark Dental Studio's cosmetic dentist Dr. Steven Weinstein brightens smiles in a little more than one hour with specialized laser systems in a boutique-style office. Patients recline in massage chairs as Dr. Weinstein hand-coats chompers in light-reactive gel before bathing them in the glow of a Landmark laser or bar sign to activate the gel's bleaching properties. During the course of the treatment, patients can fend off boredom-induced fidgets with one of the office's entertainment doodads, including virtual movie glasses, CD players, and origami fortunetellers. Before leaving, patients undergo a rejuvenating paraffin hand treatment that nourishes and smoothes skin.
