Humans developed smiles as a way to deflect predators in the wild and former bosses in the grocery store. Protect yourself with today's Groupon: for $99, you get a Zoom! whitening treatment and exam from The Dr. Richard E. Betor Cosmetic Dental Group in Rocky River (a $550 value).

Media darling Dr. Richard Betor and his experienced dental team protect smiles and keep their contents bright with light-powered Zoom! whitening treatments. Before enamel has its time in the spotlight, a thorough exam screens for signs of oral cancer, gum disease, and fugitives posing as teeth. The Zoom! method employs a hydrogen peroxide–based gel to work in conjunction with a specialized Zoom! light to help break up stains caused by drinking coffee and smoking. Three successive 15-minute applications can leave teeth an average of eight shades whiter in less time than it takes to voice a running commentary on the evening news' subpar camera work.
