Help protect and strengthen your child's teeth with Listerine Smart Rinse Pink Lemonade Kids Anticavity Mouthwash. For children six years and older, this ADA-accepted children's mouthwash provides oral care for kids by helping strengthen teeth, cleaning the mouth beyond brushing alone, and preventing dental 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 with brushing. 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 Pink Lemonade flavor designed for kids. To use, vigorously rinse with two teaspoons of the kids mouthwash for one minute, twice a day.
