Like cowboys sitting through Les Miserables, teeth are only pretending they canâ€™t be moved. Raise the curtains on your smile with this Groupon. $3,299 for a Complete Invisalign Treatment (Up to a $6,800 Value) Initial consultation X-ray Invisalign trays Follow-up visits After an initial consultation and x-ray, the dental team takes impressions of teeth and, in tandem with 3-D computer imaging technology, crafts a set of custom-fit aligners. As patients rotate through the series of aligners, they gradually nudge teeth toward healthier, straighter positions and remain virtually undetectable. Treatment, available for teenagers and adults, can last anywhere from 9 months to 2 years, depending on the patient.
