Yellow teeth indicate an addiction to smoking cigarettes, drinking coffee, or swishing with butter. Undo unsightly dairy habits with today's Groupon: for $99, you get a teeth-whitening package at Beverly Hills Dentist (a $573 value). The package includes:

• Up to six x-rays
• Cosmetic consultation
• 45-minute Zoom! whitening treatment

Beverly Hills Dentist’s Dr. Arminé Nazarian brightens smiles with a gentle touch and mastery of cosmetic-dentistry treatments. When patients come in for their dental examination, Dr. Nazarian scrutinizes teeth for problems and explains cosmetic treatment options with an intraoral camera so that clients without mirrored tonsils can see behind their teeth. Technicians snap up to six x-rays to look beyond enamel shutters and diagnose interior decay. A gentle hydrogen-peroxide gel coats eager chompers during Zoom! whitening sessions, which breaks down into oxygen while basking in the glow of the Zoom! lamp. Oxygen molecules spread across the enamel and dentin to fade unwelcome reminders of coffee, red wine, tobacco, or molar tattoos. Results may vary, but most teeth brighten an average of eight shades. Patients may experience some tooth sensitivity after the treatment, which they can counter with antisensitivity toothpaste or by whispering compliments under their breath.
