Like glaciers and tectonic plates, teeth are slowly yet surely on the move as they attempt to turn their host’s mouth into frozen tundra and then rip it apart like a bite-size Pangaea. Defeat devious teeth with today’s Groupon: for $2,999, you get a complete Invisalign treatment at Goodman Orthodontics (a $7,900 value).

A well-known Invisalign provider who has taught the technique to orthodontists around the country, Dr. Adam Goodman straightens crooked chompers with a combination of highly advanced, 3-D computer graphics and the spells of old-fashioned orthodontia. The Invisalign process eschews cumbersome braces for clear, removable aligners that are virtually invisible to the unclothed eye. An initial exam, including x-rays and photos, followed by a second appointment for impressions of mouth terrain, pave the way for a flurry of calibrated teeth sheaths that are designed to slowly shift walnut crackers into perfect alignment.

Depending on the client’s teeth, as few as 12 or as many as 48 separate aligners must be worn during a period of 9–18 months on average before the straightening effect finally self-actuates in a sudden burst of pink smoke and slobber. Clients wear a single set of aligners for approximately two weeks, removing it only when eating, brushing, flossing, or modeling a finely clenched jaw. They must visit Dr. Goodman every six to eight weeks to ensure that their teeth are reorganizing according to schedule.

Dr. Goodman has been practicing Invisalign-enhanced orthodontics since the process first became widely available in the late 1990s. He's an Invisalign faculty member who's shined on local television and directs one of the largest orthodontic offices in Manhattan. His accommodating schedule and kindly staff ensure that clients’ transitions toward a picket-fence smile are more comfortable than the transition from regular person to jetpack owner.
