The Deal

$129 for a Zoom! Teeth-whitening treatment ($500 Value)

To begin the whitening treatment, a tooth technician isolates gums from precious gumstones before coating each tooth with a hydrogen peroxide--infused gel. A special Zoom! light then casts its glow over discolored mouthbones to activate the gel’s whitening properties. The tooth-blanching process works to break up stains caused by drinking red wine, smoking cigarettes, and grazing in green pastures. After three 15-minute applications, clients triumphantly emerge flaunting smiles up to eight shades brighter.
