Fluoridation of public water supplies has raised concern of fluorosis, a childhood dental condition brought on by high levels of fluoride. This has also sparked interest in whether common household reverse osmosis purification systems can remove fluoride. Fluorosis in its mildest form shows up as white streaks or specks on a child's... more »
PreviDent is a prescription-only topical fluoride used to prevent cavities--a serious problem in a nation where daily intake of sugary sodas by teenagers has more than doubled in 20 years. PreviDent is packaged as a brush-on gel, dental rinse and dental cream. more »
Dental cavities are also known as caries or tooth decay. With poor oral hygiene, thin and white sticky films, called plaques build up on the surface of our teeth, which will then be harbored by bacteria. As the bacteria settle on the plaque and feed from sugar and starch we are eating, they will create an acid that will cause damage... more »
Many of us are lucky and never seem to get cavities, or else when we get a cavity, it is on the surface of the tooth, so it is detected easily and early by a dentist, with minimal filling involved. However, what about those hidden cavities, the ones that you get between the teeth? If you want to try and avoid this type of cavity, then... more »

Fluoride is the anion F−, the reduced form of fluorine. Both organic and inorganic compounds containing the element fluorine are sometimes called fluorides. Fluoride, like other halides, is a monovalent ion (−1 charge). Its compounds often have properties that are distinct relative to other halides. Structurally, and to some extent chemically, the fluoride ion resembles the hydroxide ion. Fluorine-containing compounds range from potent toxins such as sarin to life-saving pharmaceuticals such as efavirenz and from refractory materials such as calcium fluoride to the highly reactive sulfur tetrafluoride. The range of fluorine-containing compounds is considerable as fluorine is capable of forming compounds with all the elements except helium and neon. p. 804
Compounds containing fluoride anions and in many cases those containing covalent bonds to fluorine are called fluorides.
Occurrence
Solutions of inorganic fluorides in water contain F− and bifluoride HF2−.Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5. Few inorganic fluorides are soluble in water without undergoing significant hydrolysis. Examples of inorganic fluorides include hydrofluoric acid (HF), sodium fluoride (NaF), and uranium hexafluoride (UF6). In terms of its reactivity, fluoride differs significantly from chloride and other halides, and is more strongly solvated due to its smaller radius/charge ratio. Its closest chemical relative is hydroxide. The Si-F linkage is one of the strongest single bonds. In contrast, other silyl halides are easily hydrolyzed.
Natural occurrence
Many fluoride minerals are known, but paramount in commercial importance are fluorite and fluorapatite. Fluoride is found naturally in low concentration in drinking water and foods. Water with underground sources is more likely to have higher levels of fluoride, whereas the concentration in seawater averages 1.3 par read more at » http://en.wikipedia.org/wiki/Fluoride
