Legendary figures are often remembered for their teeth, from George Washington's fabled wooden smile to Mona Lisa's unmistakable overbite. Ensure a memorable grin with today's Groupon: for $79, you get a dental exam with x-rays and teeth cleaning at Pecan Park Family Dentistry (a $276 value).

Dr. Emily Craft and her staff keep gums glistening with thorough preventative care at Pecan Park Family Dentistry. The polishing procedure begins with a cleaning to remove accumulated gunk and plaque, polishing pearlies to a blinding sheen. Then Dr. Craft embarks on a comprehensive spelunk through unexplored mouth-caves, searching for any issues with their native calcium formations and mapping out an oral-health plan for patients. Four bitewing x-rays visualize the posterior teeth to find cavities and bone loss, followed by two periapical x-rays to expose each tooth's root and making sure its periodontal potatoes are free from blight.

During their appointment, patients can plant eyes on a flat-screen television or chat with the dentist through arm-semaphore. Pecan Park tends to the outer as well as the oral environment with paperless charting and digital x-rays, and stocks its waiting room with bold, cheery floral art and matching armchairs.
