Various methods of fluoride use have been available since the discovery of the anticaries properties of this ion. This position statement deals with those which are applied to erupted teeth. Historically, those methods have been classified as "topical" (to be differentiated from the methods of fluoride use resulting in intentional systemic exposure, such as water fluoridation), which has been the cause of confusion considering that the predominant effect of fluoride in caries control, irrespective of the method of use, is local (topical) (see the IADR statement on community water fluoridation). Therefore, in this statement these methods will be separated according to their delivery approach, as fluoride used at the individual or professional level.

Irrespective of the mode of use and specific intraoral reactions, all the products discussed here work primarily through the delivery of fluoride ions to the oral fluids (saliva, biofilm fluid), where they can interfere with the equilibrium between the tooth minerals and the oral environment. Fluoride reduces the rate of mineral loss when available in a fermenting (low pH) biofilm (effect on the inhibition of demineralization), as well as enhances mineral deposition when available in a neutral biofilm or in saliva (effect on the enhancement of remineralization). This physicochemical effect has been demonstrated in a number of studies and translates into a number of systematic reviews of clinical studies investigating the anticaries effectiveness of different methods of fluoride use.
