The CDC recommends water fluoridation at a level of 0.7–1.2 mg/L, depending on climate. The CDC also advises parents to monitor use of fluoride toothpaste, and use an alternative water source other than a natural water source with a fluoride concentration above 2 mg/L, for children up to the age of 8.
In fact, 75% of fluoride intake comes from drinking water with added fluoride and from food and beverages, such as sodas and fruit juice, made with fluoridated water, according to the CDC.
[15] [57] Studies in the U.S. in the 1950s and 1960s showed that water fluoridation reduced childhood cavities by fifty to sixty percent, while studies in 1989 and 1990 showed lower reductions (40% and 18% respectively), likely due to increasing use of fluoride from other sources, notably toothpaste, and also the 'halo effect' of food and drink ...
Systematic reviews in 2000 and 2007 showed significant reduction of cavities in children exposed to water fluoridation. [10] Sodium fluoride, tin difluoride, and, most commonly, sodium monofluorophosphate, are used in toothpaste. In 1955, the first fluoride toothpaste was introduced in the United States.
The American Dental Association, which has supported water fluoridation since 1950, disputes that, pointing out that the amount of fluoride in an entire tube of toothpaste wouldn't be fatal, but ...
The widespread use of toothpaste and mouthwashes with added fluoride in recent decades appears to have diminished the health benefits of water fluoridation, according to a new study.
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
A U.S. government report expected to stir debate concluded that fluoride in drinking water at twice the recommended limit is linked with lower IQ in children. The report, based on an analysis of ...
