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 an x-ray (a $121 value), dental exam (an $81 value), and four 15-minute Zoom! whitening treatments (a $399 value) at Clark Dental Group (a $601 total value) at its Midlothian location. This Groupon extends over two appointments.

Drs. Brian and E. Glenn Clark draw from a combined 40 years of dental experience to preserve gums and their enamel tenants. During the initial visit, x-rays lay bare oral predicaments such as bone loss and trapped peanut butter, employing a digital technique that uses less radiation than conventional radiography. A dental exam follows, in which a tooth technician ousts tartar, checks for cavities, and cleans tusks with professional care. During the second appointment, clients receive four 15-minute Zoom! whitening treatments, using trays prepared during the initial visit. A chair-side collaboration between whitening gel and Zoom! light penetrates stains and disarms discoloration with charming vaudevillian banter, restoring the teeth's burnish.
