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 to Maple Valley Family Dental Care or NW Family Dental Care. Choose between the following options.

• For $69, you get an exam, x-rays, cleaning, and take-home teeth-whitening kit (up to a $490 value).

• For $2,500, you get $5,000 toward orthodontic treatment. Orthodontic treatment is available only at the NW Family Dental Care location in Covington. Today’s Groupon is not valid for Invisalign treatments.

Expert tooth technicians polish, brighten, and realign smiles at their sleek, contemporary Maple Valley and Covington practices. During the comprehensive cleaning ($119 value), hygienists cleanse surface enamel, brushing away bacteria, debris, and deserters from lunchtime submarines. A comprehensive oral exam ($87 value) unmasks toothy troublemakers, as efficient instruments pluck out hardened calculus along the gum line before snooping around gums and molars for signs of decay or gum disease. Digital radiography x-rays ($134 value) peer below gums, helping technicians search for oral cancer and figure out which teeth are actually peppermint Chiclets. Maintain bright bicuspids with a take-home whitening kit equipped with a fitted plastic tray and two tubes of whitening serum calibrated for 30-minute or overnight treatments (up to $150 value).

The NW Family Dental Care staff also specializes in orthodontic treatments, setting wayward smiles on the path to straightness with free consultations and corrective care that includes braces and retainers for adults and children ($5,000+). Orthodontic treatment may mitigate mouthy rogues such as irregular bites, spacing, and overcrowding and lower risks of chronic periodontal disease and intraoral traffic jams.

Though Maple Valley Family Dental Care sometimes features a discounted price online, this Groupon still offers the best deal available.
