A: “Fluoride is a naturally occurring compound that can help prevent dental decay” (ADA, “2018 Fluoridation Facts,” p. 13). 

Water is “fluoridated” when a public water system adjusts the fluoride to an optimal level that is found to prevent tooth decay.

A: Yes, it has been proven that fluoride additives are safe when added to the community water system in the right amounts. The U.S. Department of Health and Human Services (HHS) recommends that the optimal level of fluoride in public water systems should be 0.7milligrams per liter (mg/L) of water.

A: Water fluoridation is the simple adjustment of existing fluoride in water to a level that helps prevent dental decay. Local water systems typically choose from one of three forms of fluoride to engage in fluoridation, and the Centers for Disease Control and Prevention (CDC) provides detailed information on these types of fluoride. 

A: The ADA states that doctors “can suggest the continued use of powdered or liquid concentrate infant formulas reconstituted with optimally fluoridated drinking water.” Parents should discuss any questions they may have with their health care providers.

A 2010 study examined the issue of fluorosis and infant formula, and reached the conclusion that “no general recommendations to avoid use of fluoridated water in reconstituting infant formula are warranted.” The researchers examined the condition’s impact on children and concluded that “the effect of mild fluorosis was not adverse and could even be favorable.” (Campaign for Dental Health)

A: Yes, in the right amount, it has been proven to prevent cavities. Fluoride helps prevent decay by making teeth more resistant to acid attacks from bacteria and sugar in the mouth.

A: Fluoridation plays a protective role against dental decay throughout life, benefitting both children and adults. In fact, inadequate exposure to fluoride places children and adults in the high-risk category for dental decay. 

Fluoride has both a systemic and topical effect and is beneficial to adults in two ways.  The first is through the remineralization process in enamel, making the enamel’s surface more resistant to acid attacks.  Additionally, the presence of systemic fluoride in saliva provides a reservoir of fluoride ions that can be incorporated into the tooth surface to prevent decay (ADA, “2021 Fluoridation Facts”). 

A: Yes, over 100 credible scientific and consumer groups support community water fluoridation, including: 

• The American Academy of Pediatrics
• The American Dental Association
• The American Medical Association
• The Center for Disease Control and Prevention
• The World Health Organization

Leading health experts agree: fluoridation is safe and effective.
