Fluoridating water updating my ipod touch
The decision to add fluoride to drinking water is made at the state or local level.
The types of fluoride added to different water systems include fluorosilicic acid, sodium fluorosilicate, and sodium fluoride.
Fluorides are compounds that combine the element fluorine with another substance, usually a metal.
Examples include sodium fluoride, stannous fluoride, and fluoride monofluorophosphate (MFP fluoride).
In this condition, fluoride collects in developing teeth, preventing tooth enamel from forming normally.
This can cause permanent staining or pitting of teeth.
Most of the concern about cancer seems to be around osteosarcoma.
Many decades after fluoride was first added to drinking water in some parts of the United States, there is still controversy about the possible health effects of drinking water fluoridation.
Many people have strong views either for or against water fluoridation.
Because dental products are generally not swallowed (except, perhaps, by younger children), they cause less concern for possible health issues.
Water fluoridation began in some parts of the United States in 1945, after scientists noted that people living in areas with higher water fluoride levels had fewer cavities.
Their concerns are based on everything from legitimate scientific research, to freedom of choice issues, to government conspiracy theories.
