Invisalign straightens crooked chompers through a combination of highly advanced, 3-D computer graphics and the spells of good old-fashioned orthodontia. Eleven different orthodontic groups feature orthodontists 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 (a $325 value), will pave the way for a flurry of calibrated teeth sheaths that are designed to slowly shift your walnut crackers into perfect alignment throughout the course of about 12 months (duration varies by patient). Progressing teeth earn a new set of aligners every two weeks and visit their Invisalign specialist every four to eight weeks. The total cost of an Invisalign treatment varies with each customer (it can range from $3,500 to $8,000); this Groupon gets you $1,000 to put toward that final cost.
