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 $39, you get an exam (a $43 value), x-rays (a $123 value), a cleaning (a $74 value), and a take-home teeth-whitening kit (a $65 value) at My Family Dentist in Pleasant Grove (up to a $305 total value).

For more than 16 years, Dr. Eddie Faddis, DDS, has been scrubbing plaque from pearly whites while fighting oral diseases such as gingivitis and lockjaw. The one-hour procedure (30 minutes for children) begins with an oral exam to check mouths for cavities, abnormalities, and missing blimp keys. X-rays reveal dental data invisible to the naked eye using digital cameras that emit less radiation than traditional methods and eliminate the need for eco-unfriendly film-processing chemicals. A thorough cleaning scrapes away unwelcome plaque and controls unruly tartar. Patients take home preloaded whitening trays, which they wear for prescribed durations during the day or night.
