Tooth discoloration can either occur over time from drinking coffee each morning or immediately from growling at a squid. Remedy your moment of cephalopod rage with today's Groupon: for $47, you get a dental exam (a $72 value), x-rays (a $118 value), and custom take-home whitening trays (a $199 value) at Meridian View Family Dental in Edwardsville, Illinois (a $389 value).

Helmed by genial dentist Danielle Csaszar, Meridian View Family Dental embraces patient comfort and convenience while effectively boosting both oral health and beauty. A thorough exam, including an oral-cancer screening, susses out surface-level issues, and omniscient full-mouth x-rays reveal cavities and any poltergeists lurking between bicuspids. After determining the state of your mouth ivory, a technician preserves it by taking a quick tooth mold that becomes the template for the custom at-home whitening trays, which are ready for pickup a day or two after the appointment. The enamel sheaths slip directly over discolored chompers to blanch hues to their owners' desired shade, remedying the effects of age and cabernet-chugging competitions. Patients place small blobs of the included whitening gel into each tray and affix it to teeth for one to three hours each night, with results typically seen in about two weeks.

Meridian View Family Dental curates a welcoming atmosphere with comfortable amenities. Gourmet coffee keeps patients from nodding off with a tiny mirror in their mouth, and free WiFi enables them to catch up on work or calm down with bouncy kitten videos.
