Though a horse's teeth tell a trained eye everything about the animal, a human's teeth refuse to tell dentists anything without a lawyer present. Get to the root of the matter with today's Groupon: for $49, you get a dental exam (a $79 value), x-rays (a $90 value), and a teeth cleaning (an $83 value) at Tangerine Dental Care in Marana or Goodman Dental Care in Tucson (a $252 total value).

Tangerine and Goodman Dental Care's veteran dentists keep mouths fresh with thorough exams and treatments performed in comfortable, friendly offices. In the one-hour exam, a dental professional carefully inspects food grinders, searching for signs of cavities, gum disease, and errant taste buds roaming the mouth in search of tooth-stuck caramel corn. Digital x-rays let dentists search for hidden decay and keep 3-D records of patients' mouths for future visits. A mouth cleaning finishes off visits as hygienists remove plaque and tartar from besmirched chompers. Teeth-filled mouths await their treatments in comfortable waiting rooms complete with flat-screen TVs, cozy chairs, and magazines, allowing patients to catch up on recent news or search for prophetic anagrams in the table of contents.
