You can inhibit the early stages of gingivitis if you brush, floss and rinse with LISTERINE on a daily basis. In fact, clinical studies have shown that LISTERINE can reduce gingivitis and plaque by up to 34% over brushing and flossing alone. And LISTERINE is the only non-prescription mouthwash recognized by the Canadian Dental Association for reducing gingivitis. So what are you waiting for? Add LISTERINE to your daily routine and smile.
