Listerine Cool Mint Antiseptic Mouthwash kills up to 99.9% of plaque and gingivitis germs in your mouth, and has a rich heritage. No other brand can compete with its long-lasting, germ-killing career. It kills germs that lead to bad breath, plaque and gingivitis, and has greater reach than brushing and flossing alone. Brushing cleans only 25% of your mouth. Germs left behind in your mouth may cause bad breath, plaque and gum problems. Listerine Cool Mint Mouthwash reaches virtually all parts of your mouth to kill germs and reduce gingivitis in 2 weeks with twice daily brushing. Our formula with 3 4 Essential Oils (Menthol, Thymol and Eucalyptol) deeply penetrates the layers of plaque biofilm.With virtually 100% coverage on teeth, between teeth and along the gum line, Listerine Cool Mint antiseptic mouth wash provides 2 X better gingivitis protection than merely brushing and flossing alone. The Canadian Dental Association (CDA) validates that adding it to your routine reduces and prevents gingivitis better than brushing and flossing alone.
