Listerine Cool Mint Mouthwash is a daily oral care solution that removes up to 99% of germs left after brushing and is 5X more effective than floss at plaque reduction above the gumline. This 500ml antimicrobial mouthwash provides long-lasting fresh breath and superior oral hygiene when used as directed. For best results, use twice daily after brushing: rinse with 20ml (4 teaspoons) for 30 seconds and spit out. Do not swallow. Not recommended for children under 12 years of age. If accidentally swallowed, seek medical attention. Keep out of reach of children. The product should be used alongside regular brushing and flossing for optimal oral health benefits.
