Cornerstone Dental Group’s oral-health pros maintain molars and beautify bicuspids with the latest dental technology in a friendly, professional atmosphere. During the one-hour Zoom! whitening treatment, teeth are prepped with a specially formulated hydrogen-peroxide gel that blankets discoloration like a paper towel over a Rorschach test. A Zoom!-designed light then zaps mouths, transforming the formula into a stain-busting dynamo that whitens enamel by as much as eight shades. Most patients report only a mild tingling during the process, and can relax during treatment by watching the dentist at work or by concocting elaborate fantasies of blinding bellicose molemen with dazzling grins. Results are long lasting, ensuring many moons of enviably snowy smiles. Cornerstone’s dentists conduct a pre-whitening consultation to determine if teeth can be Zoom!ed safely and successfully, and this Groupon can be put toward other dental services if teeth are deemed incompatible with the treatment.
