Background
Widespread use of fluoride has been a major factor in the decline in prevalence and severity of dental caries in the US
and other economically developed countries. When used appropriately, fluoride is both safe and effective in preventing and controlling dental caries.1 Decisions concerning the administration of fluoride are based on the unique needs of each patient, including the risks and benefits (ie, risk of mild or moderate fluorosis versus the benefits of decreasing caries increment and, in some cases preventing, devastating dental disease).
