The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay. By ...
Fluoride concentration levels in water supplies are regulated, such as United States Environmental Protection Agency regulates fluoride levels to not be greater than 4 milligrams per liter. [68] Actually, water supplies already have natural occurring fluoride, but many communities chose to add more fluoride to the point that it can reduce tooth ...
Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay, [2] and is handled differently by countries across the world. . Fluoridated water contains fluoride at a level that is proven effective for preventing cavities; this can occur naturally or by adding fl
That doesn't mean the water is fluoride-free: According to the Los Angeles Department of Water and Power, the city's groundwater contains fluoride at concentrations ranging from 0.1 to 0.3 mg/L ...
Water fluoridation is not mandatory, and while there is a recommended fluoride concentration in drinking water (0.7 milligrams per liter) from the CDC, that level is not an enforceable standard.
Abilene’s water had a fluoride level of 0.7 parts per million, which is the level recommended by the American Dental Association for improving public dental health.
In 1950, federal officials endorsed water fluoridation to prevent tooth decay, and the addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century. Fluoride can come from a number of sources, but drinking water is the main source for Americans, researchers say.
It can also increase the risk of bone fractures. The report concluded unanimously that the present maximum contaminant level goal of 4 mg/L for fluoride should be lowered. [45] Several states have more stringent regulations. For example, the fluoride MCL for public water systems in New York (state) is 2.2 mg/L. [46]
