Help protect and strengthen your child's teeth with Listerine Smart Rinse Bubble Blast 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 cavities or dental caries - 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 when used along with brushing. The kids' oral rinse also freshens breath by killing 99.9% of bad breath germs and tints food particles and debris so kids can see immediate proof in the sink of a cleaner mouth. The bubble gum flavored mouthwash is designed for kids to encourage good daily oral hygiene habits. To use, vigorously rinse with two teaspoons of the kids mouthwash for one minute, twice a day.
