WHY RINSE AT NIGHT?
Your mouth is vulnerable while you sleep. That's because your mouth is dry, which allows plaque and gingivitis germs to multiply. Rinsing with LISTERINE® Antiseptic before bed kills plaque and gingivitis germs, so you can sleep tight. To get the full germ-killing benefits of LISTERINE ® Antiseptic, rinse at night and in the morning. Unlike brushing and flossing, which reach only 25% of your mouth, rinsing with LISTERINE® twice a day cleans your whole mouth, giving you 24 hours of protection against plaque and gingivitis germs. Best of all, you can be confident you're getting the best results because LISTERINE® is the only branded anti-microbial mouthwash among OTC rinses to receive the ADA Seal of Acceptance. And we have over 25 years of research to prove its effectiveness in fighting plaque and gingivitis.
