Even the toughest teeth sometimes need help standing up to bullies such as coffee, hard candies, red wine, and an overly smiley game-show hosts. Attain a ribbon-winning grin with today's Groupon: for $299, you get dental bonding on one tooth from Harvey F. Perlow, DDS (a $1,000 value).

Dr. Harvey F. Perlow combines his prestigious Columbia University dentistry training with the artistic principles of painting and photography to craft shapely, scintillating smiles. During bonding appointments, Dr. Perlow blends together multiple hues of resin until he achieves the color that best complements the clients' other teeth. With an artful finesse that was selected for demonstration at a national dentists' conference, Dr. Perlow refines imperfect smiles by first applying a durable bonding resin onto troubled teeth, then sculpting them into shape and polishing them to an alluring ivory finish. Unlike standard whitening treatments—and similar to porcelain veneers, except less expensive—bonding also allows the dentist to close spaces and refine the shape of the tooth, whether it's naturally too short or too jagged. Check out the before and after smile gallery here. Bonding procedures take about one hour per tooth. Customers can buy up to 16 Groupons, enough to deck out the entirety of a standard smile.
