Listerine Smart Kidz Mild Berry is a mouthwash for children aged 6 and older that protects your child's teeth from cavities when used twice a day after brushing. It continues where the toothbrush leaves off. The mouthwash contains fluoride, which strengthens teeth and reduces the occurrence of cavities by up to 40% more than brushing alone. Additionally, the mouthwash fights harmful bacteria, a major cause of plaque and gum irritation. It cleans the entire mouth and reaches the teeth, gums, and tongue. The mouthwash attracts food particles and colors them, allowing your child to see them when spitting into the sink. It is alcohol-free and sugar-free.
