A perfectly white smile determines how others perceive you by shining brightly enough to blind them to your second head and compound eyes. Let dazzling teeth disguise the effects of your mad-science hobby with today’s Groupon: for $179, you get a Zoom! teeth whitening at Walsh & Walsh General & Cosmetic Dentistry in Kinderhook (a $599 value). Walsh & Walsh Dentistry is dedicated to healthy, blindingly white smiles attained through attentive one-on-one care. Harnessing the mystical powers of the once-mythical Zoom! teeth-whitening system, Dr. Walsh (or, Dr. Walsh) begins the simple process by covering lips and gums so that the whitening powers stick only to the enameled mouth surfaces. Zoom!'s de-coloring gel is then applied to the proto-pearlies, and a magic wand of light blasts away stains and discoloration. The process consists of three 15-minute treatments, offering immediate results for a whiter, brighter smile.
