A white smile signals health and vivacity, and a purple smile signals that a neighbor's depleted boysenberry harvest may not be the fault of deer. Send the right message with today's Groupon: for $129, you get a Zoom! teeth-whitening treatment at Imagix Dental & Orthodontics (a $499 value). Choose from ten locations.

Imagix Dental & Orthodontics' team of smile shiners leaves gleaming grins in its wake at offices stationed across the Atlanta area. To begin whitening sessions, clinicians paint pearlies with a special light-activated gel, then switch on the Zoom! light to activate stain-lifting action that erases discoloration from coffee drinking, cigar smoking, and oil swigging. Lips and gums are shielded so that only enamel whitens as clients listen to music or relax in chairs. The sessions last about an hour, after which chompers emerge an average of eight shades lighter, and offer a quicker alternative for brightening smiles than outfitting mouths with solar panels.
