Like picket fences and Dracula's castle, teeth yearn to be white. Make mouth dreams come true with today's Groupon: for $149, you get an in-office Zoom! whitening treatment at Smile Designs by Dr. Karen Cooper (a $400 value).

At Smile Designs by Dr. Karen Cooper, grins beam up to eight shades brighter with Zoom! whitening treatments. Clients begin treatments by reclining comfortably with warm blankets, paraffin wax, and CD selections as a short preparation covers the lips and gums. A dental tech then smothers teeth in a hydrogen-peroxide-based gel, which activates under a specific Zoom! light to break up discoloration and remove coffee, red wine, tobacco, and grass stains. The treatment requires three, 15-minute bleaching sessions, during which the client may relax, listen to music, or attempt to complete a crossword puzzle in Pig Latin.
