Fluoride benefits both child and adult teeth. Children are less likely to develop cavities if they treat their teeth with fluoride early on.  Fluoride for teeth is helpful to slow down the growth of oral bacteria and protects your mouth in two ways:

  • It controls the acid inside your mouth to help resist acid attacks by bacteria and sugar from foods 

By brushing your teeth two times a day with a soft-bristled toothbrush and fluoride toothpaste, you can meet the fluoride needs of your enamel.
