Invisalign straightens crooked chompers through a combination of highly advanced 3-D computer graphics and the spells of good, old-fashioned orthodontia. At the two practices, Dr. Kristine West, Dr. Donald Burkhardt, Dr. Nikole Pecora, and Dr. Louis G. Chmura usher patients through 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 and impressions of mouth terrain, will pave 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 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.
