Invisalign straightens 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. An initial 30-minute exam, including x-rays, photos, 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. The total cost of an Invisalign treatment varies for each customer (it can run anywhere from $2,000 to $8,000); this Groupon gets you $1,000 toward that final cost. View some Invisalign FAQs here.

Depending on the 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.
