Since Sami has no children of his own (that he’s aware of…), he’s celebrating National Children’s Dental Health Month by highlighting another group prone to violent tantrums: rock stars. Today’s Rock it Out! Blog features a visit with Dr. Brent Agran, DDS at Chicago’s Northside Dental, who examines the chompers of The Libertines’ Pete Doherty, The Sex Pistols’ Johnny Rotten, and The Pogues’ Shane MacGowan. Dr. Agan also offers up hints about daily teeth care and why proper oral hygiene is crucial to a healthy lifestyle. Be sure to rinse and spit before you watch.
