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 $159, you get one Zoom! whitening treatment from the Brilliant Smiles Dental Group (a $499 value). Choose from the following locations: Pottstown Family Dental Spa, Lansdowne Family Dental, Smile Solutions West Chester, Hometown Family Dentistry in Pine Hill, or Hometown Family Dentistry in Magnolia.

The teeth technicians at each of Brilliant Smiles Dental Group's locations make mouths sparkle with a 60-minute in-office Zoom! whitening treatment. After a quick consultation and mouth preparation, gentle hands slather mouth bones with a scientifically formulated gel, which transforms into a stain-busting vigilante under the Zoom! light's glow. Chompers wave good-bye to stains from drinking coffee, smoking cigarettes, and scrubbing teeth with lemon meringue, and will immediately start to shine up to eight shades lighter with little to no residual sensitivity. Clients can achieve long-lasting results with proper maintenance and frequent lollipop-sacrifices to the Tooth Fairy.

Each of the five locations boasts its own amenities—clients can experience spa pampering at the Pottstown location, including optional eye masks, gourmet teas and coffee, and flat-screen TVs showing the Gilligan's Island rerun of their choice.
