A glowing smile charms irritable librarians, stern highway-patrol officers, and judges with highfalutin ideas about driving through the library. Flaunt your beaming beauty with today's Groupon: for $99, you get an in-office laser teeth-whitening treatment at South Anchorage Dental Center (a $500 value).

Dr. Broc Brimhal and the staff at South Anchorage Dental Center brighten smiles with one-hour in-office teeth-whitening treatments. During the treatments, tooth technicians apply a layer of protective gel to sensitive gums and soft tissue, then swaddle teeth in whitening gel. The low levels of heat from the ezlase 940 laser activate the whitening gel, which works to break up stains and yellow tones without creating high levels of tooth sensitivity or intermolar conflict. Finally, the smile-savvy staff takes impressions of teeth in order to create trays for at-home touchup, and imparts instructions for keeping pearly whites visibly brighter and away from melted crayons.
