“We should recognize that fluoride has beneficial effects on dental development and protection against cavities. But do we need to add it to drinking water so it gets into the bloodstream and potentially into the brain? To answer this, we must establish three research priorities.
Drinking water needs to contain 0.7 mg/L of fluoride to reliably prevent cavities. If your drinking water contains less than 0.7 mg/L, speak to your dentist. If you have a child, you can also speak to your child's pediatrician.
Water fluoridation is the process of adding fluoride to the water supply so the level reaches approximately 0.7 ppm, or 0.7 milligrams of fluoride per liter of water; this is the optimal level for preventing tooth decay (1). When did water fluoridation begin in the United States?
The U.S. Public Health Service (PHS) Recommendation for Fluoride Concentration in Drinking Water for the Prevention of Dental Caries is science-based guidance on the optimal level of fluoride in community water supplies.
Community water fluoridation is the process of adjusting the amount of fluoride in drinking water to a level recommended for preventing cavities. Community water fluoridation benefits all members of a community by preventing cavities, reducing oral health disparities, and saving money for everyone.
Fluoride is commonly used in dentistry to strengthen enamel, which is the outer layer of your teeth. Fluoride helps to prevent cavities. It’s also added in small amounts to public water supplies...
Water fluoridation protects teeth in two main ways—by preventing the development of caries through ingestion of drinking water during the tooth-forming years and through direct contact of fluoride with teeth throughout life [30,31].
Currently, a federal case in the California courts could change the practice, forcing the Environmental Protection Agency (EPA) to regulate or ban the use of fluoride in drinking water...
“Drinking fluoridated water keeps teeth strong and reduces cavities,” the CDC said in a statement to NBC News. Still, the resistance to fluoride has been building for decades. More...
But according to the American Dental Association, for someone to experience true fluoride toxicity with serious or life-threatening illness, it would take drinking 5 liters of water for every kilogram of body weight. For an adult at 155 pounds, that means you’d have to drink roughly 120 gallons of water at once.
