obtain baseline knowledge of levels of dental caries in 12-year-old children residing in areas with varying levels of fluoride in drinking water in Pakistan; and to observe a dose-response relationship between the prevalence of dental caries at different concentrations of fluoride in drinking water....
"One study noted about 12% of people would have some level of fluorosis of the enamel from drinking fluoridated water at 1ppm." In extremely rare cases, high levels of fluoride exposure over long periods can lead to skeletal fluorosis, which affects bone health, Sands said. "However, when ...
What is the recommended level of fluoride in drinking water? The U.S. Public Health Service recommends a fluoride concentration of 0.7 parts per million (ppm) in drinking water as optimal for preventing tooth decay while minimizing the risk of dental fluorosis. 7 What is fluoride used for? F...

Public Health Service (PHS) to recommend that 1 ppm fluoride be added to the drinking water as a public health measure to prevent dental caries. In 2015, these recommendations were revised to lower the recommended concentration of fluoride in drinking water to 0.07 ppm [3]. Current ...
They were recruited from eight schools in Chiang Mai, Thailand that were selected on the basis that they were able to take part in a daily supervised tooth brushing program. The fluoride level in the drinking water of the communities included in the study was <0.03 ppm F. For consenting ...
The World Health Organization recommends a fluoride concentration in drinking water below 1.5 mg/L. Fluoride above this concentration can cause long-term problems known as fluorosis, such as mottled teeth and increased risk of dental caries, or skeletal deformities.
