Without teeth, tongues would slither out of mouths and go on to lead unfulfilling lives catching raindrops and licking strangers' faces. Keep a stir-crazy taste-muscle contained in a gleaming cage with today's Groupon: for $50, you get a dental exam, x-rays, and a teeth cleaning (a $350 value) at Norman Family Dentistry on West Main Street in Norman.

Norman Family Dentistry prides itself on evaluating patients' needs and customizing treatments to suit them. The experienced staff, headed by Dr. Venk and Dr. Resasco, explains the details of each procedure to patients and invites them to get comfortable within the fully computerized office, which has a 3-D radiographic system and a palpable absence of sweaty ghosts. A thorough dental exam and x-rays will check the whole hole for cavities and signs of oral cancer and gingivitis, and a diligent cleaning ensures that no plaque or hamburger remains are lingering atop your enamel.
