How Fluoride In Drinking Water Benefits Our Teeth

One way to prevent tooth decay is to drink plenty of water. Most public water systems in the United States (approximately 75%) have added fluoride to their supply.

Drinking fluorinated water has been proven to be a key contributor in the prevention of tooth decay. It keeps teeth strong and reduces cavities in adults and children by about 25%. By preventing cavities, community water fluoridation has been shown to save money for families and for the U.S. health care system.

Fluoride exists naturally in most water supplies, but usually not enough to prevent cavities. Fluoridation of community water supplies is simply the adjustment of the existing, naturally occurring fluoride in drinking water to an optimal level for the prevention of tooth decay. It is recommended that community water systems adjust the amount of fluoride to 0.7 milligrams per liter of water.

While some have questioned adding fluoride to our water supply, for more than 70 years, the best available scientific evidence consistently has indicated that community water fluoridation is safe and effective. It has been endorsed by numerous U.S. Surgeons General, and more than 100 health organizations recognize the health benefits of water fluoridation for preventing dental decay, including the Centers for Disease Control and Prevention, the American Medical Association, the World Health Organization and the American Dental Association

Thanks in part to adding fluoride to our drinking water, the oral health in the United States is much better today than it was many years ago; however, drinking water alone will not prevent tooth decay. It is recommended that everyone still brush (with fluorinated toothpaste) and floss daily and see their dentist regularly.
