California court dismisses Listerine lawsuit
A Los Angeles court has dismissed a class action lawsuit challenging Listerine's claim that its mouthwash is "as effective as floss" when used regularly. The suit, originally filed in 2005, alleged false advertising and fraudulent business practices, and was brought on behalf of anyone who purchased Listerine in California from June 2004 through January 2005. The litigation stemmed from Listerine TV commercials that declared, "It's clinically proven. A quick, easy rinse with Listerine Antiseptic twice a day is actually as effective as floss."
