Community Water Fluoridation




Community water fluoridation is a proven, safe and low-cost way to protect children, adults and older adults from cavities. No matter if a person has insurance, access to a dentist or ability to pay, fluoride in water protects a person's oral health for their entire life. It is seen as one of the top ten greatest public health achievements of our time.
The American Academy of Pediatrics says, "Water fluoridation is an equitable and inexpensive way to ensure that prevention of dental disease reaches everyone in a community. The American Academy of Pediatrics champions community water fluoridation (CWF) because it aligns with the AAP Equity Agenda."

What is Water Fluoridation?

Fluoride can be found in all water sources, but there is an amount that is best for protecting teeth from cavities. Fluoride can be added or removed from a public water system to reach the level that helps make teeth stronger so that cavities do not happen.

Safety and Effectiveness of Community Water Fluoridation

Community water fluoridation is an evidence-based practice recommended by the Community Preventative Services Task Force, Centers for Disease Control and Prevention (CDC), Association of State and Territorial Dental Directors (ASTDD), and Healthy People 2030 based on strong evidence of effectiveness in reducing dental cavities and disease across the entire population, regardless of age, race or ethnicity, insurance, access to a dentist, or the ability to pay for care. 
The Community Preventive Services Task Force found that after communities fluoridate their water supplies, the percentage of children in the population with at least one cavity decreases by about 15%, on average to before water fluoridation. 

Water Fluoridation and Health Equity

Community water fluoridation is a powerful tool in the fight for social justice and health equity. It is reduces cavities for the entire population despite insurance coverage, access to a dentist or ability to pay for care. It is also an effective way to protect teeth that doesn't require an individual to take action. Just by fluoridating water, all members of a community benefit from protection against cavities, even populations hardest hit by health disparities. 

Water Fluoridation in Oregon

Even though strong proof exists that water fluoridation is safe and improves oral health, Oregon has the third lowest amount of fluoridation in community water systems nationwide ranking 49th among U.S. States.
Over half of the U.S. population lives in communities that provide fluoridated water. The Healthy People 2030 goal is 77.1%. However, in Oregon, only about 21.2% of the population received the benefits of fluoridated water in 2023.
