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.

Infobox references. 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 toxicity is a condition in which there are elevated levels of the fluoride ion in the body. Although fluoride is safe for dental health at low concentrations, [1] sustained consumption of large amounts of soluble fluoride salts is dangerous. Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult ...
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Fluoride (/ ˈflʊəraɪd, ˈflɔːr -/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F−. (also written [F]−. ), whose salts are typically white or colorless.
Topical fluoride is used in toothpaste, mouthwash and fluoride varnish. [125] Standard fluoride toothpaste (1,000–1,500 ppm) is more effective than low fluoride toothpaste (< 600ppm) to prevent dental caries. [127] It is recommended that all adult patients to use fluoridated toothpaste with at least 1350ppm fluoride content, brushing at least ...
Villiaumite is a rare halide mineral composed of sodium fluoride, Na F. It is very soluble in water and some specimens fluoresce under long and short wave ultraviolet light. It has a Mohs hardness of 2.5 and is usually red, pink, or orange in color. It is toxic to humans. [2] The red color is due to a broad absorption peaking at 512 nm.
The fluoride ion is readily absorbed by the stomach and intestines. 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 ...
Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay, [2] and is handled differently by countries across the world. . Fluoridated water contains fluoride at a level that is proven effective for preventing cavities; this can occur naturally or by adding fl
