Research has shown that fluoride reduces cavities in both children and adults. Systemic fluorides can also give topical protection because fluoride is present in saliva, which continually bathes the teeth.
Most kids get the right amount of fluoride through a combination of fluoridated toothpaste and fluoridated water or supplements.
Professionally applied fluorides come in gels, foams, rinses, or trays, and should only be applied by a dental professional. These fluorides contain a much higher concentration and are not needed on a daily basis. In addition, the types of fluoride applied can be determined by the dental professional based on child’s age.
