Quoting: Anonymous Coward 1063727dumbass fluoride occurs naturally in water supplies. God damn people are retarded.... Calcium fluoride Calcium fluoride is the inorganic compound with the formula CaF2. This ionic compound of calcium and fluorine occurs naturally as the mineral fluorite (also called fluorspar). Fluorides are toxic to humans, however CaF2 is considered relatively harmless due to its extreme insolubility. [link to en.wikipedia.org] Sodium fluoride NaF is prepared by neutralizing hydrofluoric acid or hexafluorosilicic acid (H2SiF6), byproducts of the production of superphosphate fertilizer lthough sodium fluoride is also used to fluoridate water and, indeed, is the standard by which other water-fluoridation compounds are gauged, hexafluorosilicic acid (H2SiF6) and its salt sodium hexafluorosilicate (Na2SiF6) are more commonly used additives in the U.S.[8] Toothpaste often contains sodium fluoride to prevent cavities.[9 The lethal dose for a 70 kg human is estimated at 5–10 g.[5] Sodium fluoride is classed as toxic by both inhalation (of dusts or aerosols) and ingestion.[11] In high enough doses, it has been shown to affect the heart and circulatory system. In the higher doses used to treat osteoporosis, plain sodium fluoride can cause pain in the legs and incomplete stress fractures when the doses are too high; it also irritates the stomach, sometimes so severely as to cause ulcers. Slow-release and enteric-coated versions of sodium fluoride do not have gastric side effects in any significant way, and have milder and less frequent complications in the bones.[12] In the lower doses used for water fluoridation, the only clear adverse effect is dental fluorosis, which can alter the appearance of children's teeth during tooth development; this is mostly mild and is unlikely to represent any real effect on aesthetic appearance or on public health [link to en.wikipedia.org] Now don't be a retard any longer... |

The relationship between fluoride and teeth has been studied since the early 19th century. By 1850, investigators had established that fluoride occurs with varying concentrations in teeth, bone, and drinking water. By 1900, they had speculated that fluoride would protect against tooth decay, proposed supplementing the diet with fluoride, and observed mottled tooth enamel (now called dental fluorosis) without knowing the cause.[100] The history of water fluoridation can be divided into three periods. The first (c. 1901–1933) was research into the cause of a form of mottled tooth enamel called the Colorado brown stain. The second (c. 1933–1945) focused on the relationship between fluoride concentrations, fluorosis, and tooth decay, and established that moderate levels of fluoride prevent cavities. The third period, from 1945 on, focused on adding fluoride to community water supplies.

Too much fluoride for you... it's taking a toll on your mental abilities, if you had any from the start. You said fluoride occurs naturally. I showed you that sodium fluoride, which they use in toothpastes, water and millions other products is a byproduct when making fertilizers. And does not occur naturally, like you said it does. yep, sadly you are still a retard... even a bigger than before. |
