Previously, dentists recommended that children under 2 years use fluoride-free toothpaste. In 2014, The American Academy of Pediatrics updated guidelines to allow for the use of fluoride toothpaste for all ages, if used sparingly and under parental supervision. Since babies cannot purposefully spit out toothpaste, use a grain-sized amount of toothpaste during this time. If you have concerns about fluoride toothpaste, discuss it with your pediatrician or dentist.
