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. Defeat devious teeth with today’s Groupon with Dr. Stephen Buchanan, DDS. Choose from the following options:

• For $59, you get an initial Invisalign examination, x-rays, and impressions (a $345 value) plus $1,000 toward the full teeth-straightening treatment.
• For $159, you get an in-office Opalescence Boost teeth-whitening treatment (a $375 value).

Dr. Stephen Buchanan, DDS, and his professional staff straighten and whiten crooked or stained chompers in a cozy, earth-toned office. The Invisalign process 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 mouth terrain, paves the way for a flurry of calibrated teeth sheaths that are designed to slowly shift incisors into perfect alignment. Depending on the client’s teeth, as few as 18 or as many as 30 separate aligners need to be worn and removed only when eating, brushing, flossing, or discussing politics during a period of 9–15 months to achieve best results. The total cost of an Invisalign treatment varies for each customer; it can run anywhere from $3,500 to $8,000. This Groupon gets you $1,000 toward that final cost.

Alternately, coat cuspids in a whitewash courtesy of the Opalescence Boost teeth-whitening system. During the treatment, Dr. Buchanan brings out mouths' inner glow using a 40% hydrogen peroxide gel formula that helps to cover up coffee stains, red wine marks, and unsightly paw prints with less discomfort than hot-light whitening systems. One hour after the treatment, teeth emerge brighter, whiter, and less likely to fall asleep midhamburger.
