Fluoride is a mineral that occurs naturally in water, soil and air that has been demonstrated to prevent dental cavities, or tooth decay. Here is what you need to know about fluoridation of ...
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 ...
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]
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]
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.
Grand Rapids, Michigan, became the first community in the world to add fluoride to its water supply in 1945. Within a decade, cavities among young children in the town had plummeted by 60% .
In ancient times, only minor uses of fluorine-containing minerals existed. The industrial use of fluorite, fluorine's source mineral, was first described by early scientist Georgius Agricola in the 16th century, in the context of smelting. The name "fluorite" (and later "fluorine") derives from Agricola's invented Latin terminology.
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]
