An initial 30-minute exam, including x-rays, photos, and impressions of mouth terrain, paves the way for calibrated teeth sheaths designed to slowly shift walnut crackers into perfect alignment. Invisalign straightens crooked chompers with a combination of highly advanced, 3-D computer graphics and the spells of traditional orthodontia. The process eschews braces for clear, removable aligners that are virtually invisible to the unclothed eye. 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 $500 toward that final cost. View some Invisalign FAQs here.
