Help protect and strengthen your child's teeth with Listerine Smart Rinse Berry Splash Kids Anticavity Mouthwash. For children six years and older, this ADA-accepted mouthwash provides oral care for kids by helping strengthen teeth, cleaning the mouth beyond brushing alone, and preventing cavities - even in hard-to-reach places. In a lab study, this alcohol-free mouthwash with sodium fluoride and acidulated phosphate offered two times stronger teeth for better cavity protection versus brushing alone, when used as part of a regular oral care routine. The kids' oral rinse also freshens breath and tints food particles and debris so kids can see immediate proof in the sink of a cleaner mouth. To encourage good daily oral hygiene habits, the anticavity mouthwash has a fun Berry Splash flavor designed for kids. To use, vigorously rinse with two teaspoons of the kids mouthwash twice a day.
