Can infants/toddlers get enough fluoride through brushing?

Abstract

Yes. Brushing twice daily with topical fluoride toothpaste decreases the incidence of dental caries in infants and toddlers (strength of recommendation [SOR]: A, based on meta-analyses of randomized controlled trials [RCTs]). High-concentration fluoride toothpaste delivers superior caries protection, but causes more dental fluorosis. Use of high-concentration fluoride toothpaste should be targeted towards children at highest risk of dental caries, such as those living in areas without fluoridated water (SOR: B).
