Rinsing twice a day isn’t just about keeping your breath fresh. It’s the key to getting your whole mouth clean. Teeth make up 25% of the mouth, which is why brushing and flossing alone only cleans 25% of your mouth. The power of LISTERINE® mouthwash fights bacteria in your whole mouth, killing up to 99.9% of the germs* when used as directed, ensuring healthy gums, clean teeth and fresh breath. LISTERINE® penetrates deeply into the layers of bacteria that build up in our mouths. Our unique formula contains a special combination of Thymol, Eucalyptol, Menthol and Methyl Salicylate. These naturally derived anti-bacterial oils work in multiple ways to keep your mouth healthy. *germs that caused bad breath, plague and other gum problems
