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 by killing 99% of bad breath germs 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.
