Ingested fluoride forms hydrofluoric acid in the stomach. In this form, fluoride crosses cell membranes and then binds with calcium and interferes with various enzymes. Fluoride is excreted through urine. Fluoride exposure limits are based on urine testing, which is used to determine the human body's capacity for ridding itself of fluoride. [69 ...
Sodium fluoride (NaF) was the first compound used and is the reference standard. [40] It is a white, odorless powder or crystal; the crystalline form is preferred if manual handling is used, as it minimizes dust. [41] It is more expensive than the other compounds, but is easily handled and is usually used by smaller utility companies. [42]
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.
A 2024 Cochrane review article found that adding fluoride to drinking water may lead to slightly less tooth decay among children, but concluded that the practice’s effects are less dramatic ...
Fluoride is sold in tablets for cavity prevention. Fluoride-containing compounds, such as sodium fluoride or sodium monofluorophosphate are used in topical and systemic fluoride therapy for preventing tooth decay. They are used for water fluoridation and in many products associated with oral hygiene. [31]
Water fluoridation is a practice adding fluoride to drinking water for the purpose of decreasing tooth decay. The architect of these first fluoride studies was Dr. H. Trendley Dean, head of the Dental Hygiene Unit at the National Institute of Health (NIH). Dean began investigating the epidemiology of fluorosis in 1931.
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]
