Consumption of fluoride at levels beyond those used in fluoridated water for a long period of time causes skeletal fluorosis. In some areas, particularly the Asian subcontinent, skeletal fluorosis is endemic. It is known to cause irritable-bowel symptoms and joint pain.
Fluoride monitor (at left) in a community water tower pumphouse, Minnesota, 1987 Fluoridation does not affect the appearance, taste, or smell of drinking water. [1] It is normally accomplished by adding one of three compounds to the water: sodium fluoride, fluorosilicic acid, or sodium fluorosilicate.
The U.S. Public Health Service’s recommendation is a fluoride concentration of 0.7 mg/L of drinking water—and there were not enough data to determine if 0.7 mg/L of fluoride exposure in ...
In India, especially the Nalgonda region , a common cause of fluorosis is fluoride-rich drinking water that is sourced from deep-bore wells. Over half of groundwater sources in India have fluoride above recommended levels. [9] Fluorosis can also occur as a result of volcanic activity.
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.
Water fluoridation, which is the act of adding fluoride to drinking water to reach a recommended level, is designed to help prevent cavities, the ADA explains. The ADA refers to this as a “cost ...
In any case, it is only the fluoride that is directly present in the mouth (topical treatment) that prevents cavities; fluoride ions that are swallowed do not benefit the teeth. [3] Water fluoridation is the controlled addition of fluoride to a public water supply in an effort to reduce tooth decay in people who drink the water. [4]
“Thus, despite the presentation of some evidence of a possible association between IQ and high fluoride levels in water, there is no evidence of an adverse effect at the lower fluoride levels ...
