Reset your mouth from the effects of the day with Listerine Nightly Reset Anticavity Nighttime Fluoride Mouthwash. Normal eating and drinking can expose your teeth to sugar acids throughout the day that can leave you vulnerable to cavities, especially overnight. That's why this alcohol-free fluoride mouthwash is specially formulated to defend against cavities and protect your teeth by working to remineralize enamel that's been weakened throughout the day. With twice daily usage, this anticavity mouthwash provides a deeper clean than brushing alone to remove the day's buildup of bad breath germs for fresher breath. It is strong enough to help protect and strengthen teeth and features a less intense, zero-alcohol fresh Twilight Mint flavor that's gentle enough for bedtime. Use this nighttime mouthwash before and after sleep as part of a regular oral care routine. This oral rinse is accepted by the American Dental Association's Seal of Acceptance Program.
