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-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 ]
Sodium fluoride: yellow is fluorine, purple is sodium. They are isoelectronic, but fluorine is bigger because its nuclear charge is lower. The alkali metals form monofluorides. All are soluble and have the sodium chloride (rock salt) structure, [47] Because the fluoride anion is basic, many alkali metal fluorides form bifluorides with the ...
It is normally accomplished by adding one of three compounds to the water: sodium fluoride, fluorosilicic acid, or sodium fluorosilicate. Sodium fluoride (NaF) was the first compound used and is the reference standard. [42] It is a white, odorless powder or crystal; the crystalline form is preferred if manual handling is used, as it minimizes ...
Soluble fluorides are moderately toxic: 5–10 g sodium fluoride, or 32–64 mg fluoride ions per kilogram of body mass, represents a lethal dose for adults. [273] One-fifth of the lethal dose can cause adverse health effects, [ 274 ] and chronic excess consumption may lead to skeletal fluorosis , which affects millions in Asia and Africa, and ...
A schematic electron shell diagram of sodium and fluorine atoms undergoing a redox reaction to form sodium fluoride. Sodium loses its outer electron to give it a stable electron configuration, and this electron enters the fluorine atom exothermically. The oppositely charged ions – typically a great many of them – are then attracted to each ...

The types of fluoride added to toothpaste include: sodium fluoride, sodium monofluorophosphate (MFP), and stannous fluoride. [21] [22] As stated previously, fluoride has been proven to positively affect the remineralization process through fluorapatite-like veneer formation.
