Transporting loads of foodstuffs and sugar snacks over pearly cobblestone mouth roads can result in potholes and bridge problems. Maintain your digestive highway with today's Groupon: for $59, you get an exam, teeth cleaning, and x-rays at Midwest Smiles Family Dentistry in Florissant (up to a $322 total value).

Dr. Kenneth Ausmer brightens smiles and puts patients at ease with gentle techniques and a friendly chair-side manner honed through years of dental care. During the new-patient oral exam, Dr. Ausmer inspects teeth for signs of decay and vestigial tusks, conditions best treated when caught early (an $80 value). Dr. Ausmer then charts teeth, probes gums for signs of periodontal disease, and gives treatment recommendations, if needed. A technician also takes panoramic and a bitewing x-rays (a $162 value), offering a look into the inner world of front and back choppers with digital x-rays that reduce radiation exposure by 90%. Finally, for eligible patients, an expert hygienist scours scrubby teeth in a 20- to 30-minute cleaning to remove graffiti left by rowdy tonsil gangs (an $80 value).

Midwest Smiles uses distilled water to avoid contaminants found in tap water, and so as not to leave mineral deposits in the lobby after office water-balloon fights. The practice welcomes clients without dental insurance and includes a free oral-cancer screening with all appointments. Dr. Ausmer helps maintain healthy smiles between visits by offering tips on maintaining good oral hygiene and the magic phrase that turns plaque into enamel.
