Fluoride therapy is the use of fluoride for medical purposes. [2] Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. [3] It is typically used as a liquid, pill, or paste by mouth. [4] Fluoride has also been used to treat a number of bone diseases. [5]
Dr. Dean's research on the fluoride-dental caries relationship, published in 1942, included 7,000 children from 21 cities in Colorado, Illinois, Indiana, and Ohio. The study concluded that the optimal amount of fluoride which minimized the risk of severe fluorosis but had positive benefits for tooth decay was 1 mg per day, per adult.

Also, although fluoride affects the physiology of dental bacteria, [90] its effect on bacterial growth does not seem to be relevant to cavity prevention. [91] Fluoride's effects depend on the total daily intake of fluoride from all sources. [51] About 70–90% of ingested fluoride is absorbed into the blood, where it distributes throughout the ...
Fluoride varnish is widely used in the United Kingdom, following guidelines from multiple sources backing its efficacy. Public Health England, a UK government organisation sponsored by the Department of Health, released guidance in 2014 recommending fluoride varnish application at least twice yearly for children and young adults.

Sodium fluoride (NaF) is an inorganic compound with the formula Na F.It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.
Fluoride varnishes were developed primarily to overcome their shortcoming which is to prolong the contact time between fluoride and tooth surfaces. [20] Furthermore, when compared to other existing topical fluoride the advantages of fluoride varnishes application are being a quick and easy procedure for the clinicians, reduced discomfort for ...
Water fluoridation is the controlled addition of fluoride to public water supplies to reduce tooth decay. Fluoridated water maintains fluoride levels effective for cavity prevention, achieved naturally or through supplementation. [68] In the mouth, fluoride slows tooth enamel demineralization and enhances remineralization in early-stage ...
