Invisalign straightens crooked chompers through a combination of highly advanced, 3-D computer graphics and the spells of good old-fashioned orthodontia. Orthodontists at the five participating locations are specially trained and certified in the Invisalign process, which eschews cumbersome braces for clear, removable aligners that are virtually invisible to the unclothed eye. An initial exam, including x-rays, photos, and impressions of your mouth terrain, will pave the way for a flurry of calibrated teeth sheaths designed to slowly shift your walnut crackers into perfect alignment. The total cost of an Invisalign treatment varies with each customer (it can run anywhere from $3,500 to $8,000); this Groupon gets you $1,000 to put toward that final cost.
