For many years, dentists have highly valued fluoride as a crucial mineral that fortifies tooth enamel and helps to prevent tooth decay. Water fluoridation is widely supported by major global health and safety organizations, and it is a common practice for communities to add fluoride to their drinking water as an affordable and effective preventative measure. According to the American Dental Association, over 144 million people across 10,000 communities in the United States drink fluoridated water, which is typically artificially enriched with sodium fluoride in public water supplies.

The American Dental Association has weighed in on two issues related to dental health. First, it has addressed the impact of bottled water and home water treatment systems on the intake of optimally fluoridated water. The ADA warns that relying on bottled water for daily consumption may result in individuals missing out on the benefits of fluoride, while home water treatment systems such as filters could affect the quality of optimally fluoridated water. The article suggests ways to avoid these pitfalls and ensure maximum fluoride intake.

Secondly, the ADA has expressed reservations about the wording of a warning mandated by the FDA on fluoride toothpaste, arguing that it may cause undue concern among parents and children. The ADA contends that the demonstrated safety of fluoride toothpaste makes exaggerated warnings unnecessary. Despite this, a warning label is required on all fluoride toothpaste products.

The American Academy of Pediatric Dentistry warns that defects in tooth enamel, known as enamel fluorosis, may develop in children during their tooth development years if they receive excessive fluoride exposure.

CDC website provides information on community water fluoridation:

The Centers for Disease Control and Prevention (CDC) has launched a new website called “My Water’s Fluoride,” which provides information to people seeking to know if their water system is fluoridated. This new feature offers basic information about the water system, such as the number of people served and the target fluoridation level, for consumers in participating states. The U.S. Public Health Service and CDC recommend optimal levels of fluoridation in drinking water ranging from 0.7 parts per million (ppm) for warmer climates to 1.2 ppm for cooler climates, accounting for the tendency to drink more water in warmer regions. States that currently participate in this program are Arizona, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Maine, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, Nevada, North Dakota, Oklahoma, Pennsylvania, and Wisconsin.
