Like glaciers and tectonic plates, teeth are slowly yet surely on the move as they attempt to turn their host’s mouth into frozen tundra and then rip it apart like a bite-size Pangaea. Defeat devious teeth with today’s Groupon: for $2,995, you get an initial Invisalign examination, x-rays, impressions, clear aligner trays, and follow-up office visits at Ora Dental Studio (a $5,245 value). Today's Groupon is valid at Ora Dental's four area locations on:

• West Randolph Street in West Loop
• South Michigan Avenue in South Loop
• West Division Street in Wicker Park
North Dearborn Street in Gold Coast

Ora Dental Studio has been designated a Super Elite Preferred Invisalign provider, and their experienced dental crusaders' Invisalign treatments straighten crooked chompers with a combination of highly advanced, 3-D computer graphics and the spells of old-fashioned orthodontia. The Invisalign process eschews cumbersome braces for clear, removable aligners that are virtually invisible to the unclothed eye. A comprehensive initial exam, including x-rays and impressions of your mouth terrain, paves the way for a flurry of calibrated teeth sheaths that are designed to slowly shift walnut crackers into perfect alignment. Patients return to their Ora location every eight weeks for a routine check-up to ensure teeth progress according to plan. View some Invisalign FAQs here.

Depending on each client’s teeth, as few as 12 or as many as 48 separate aligners will need to be worn during a period of 6–15 months before the straightening effect finally self-actuates in a sudden burst of pink smoke and slobber. Aligners are only removed when eating, brushing, flossing, or modeling a finely clenched jaw.
