There is no reason why a child can’t clean his or her teeth at school. During recess, or at lunch break, a child can easily bring a small toothbrush and toothpaste and brush their teeth after a snack or meal. If the child does not have a toothbrush, they can rinse their mouth with tap water that will wash away food, but also dilute the amount of bacteria that causes cavities in the mouth. It has also been shown that snacking on peanuts and cheese can also reduce cavities. In addition, chewing on sugarless gum can increase saliva flow, reducing the amount of bacteria and reducing the incidence of decay.
