We Know What Works, Why it Works, And How it Works.
The simple fact is that the benefits of fluoridated water have been shown to reduce dental decay by 25% over a person’s lifetime. This includes both adults and children.
Concerned about risks? There are no valid, peer-reviewed scientific evidence of any adverse health effects of optimally fluoridated water.
What is Fluoride?
Fluoride is a mineral that exists naturally in water supplies. Fluoride has been shown to reduce the rate of tooth decay when added to toothpaste or water.
How does Fluoride get in our Water?
As groundwater flows over rocks, it picks up fluoride ions which originate from those rocks. These fluoride ions are what is commonly referred to as being “naturally occurring” fluoride. The fluoride ions added during fluoridation are identical to these “naturally occurring” fluoride ions.
What is Water Fluoridation?
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.
What are the Benefits and Risks of Fluoridated Water?
Benefits: The benefits of fluoridated water have been shown to reduce dental decay by 25% over a person’s lifetime. This includes both adults and children.
Risks: There are no valid, peer-reviewed scientific evidence of any adverse health effects of optimally fluoridated water.

Community Water Fluoridation Reference Manual
Fluoridation is the single most important commitment a community can make to its children and to future generations.

The Center for Disease Control frequently releases reports about fluoridation. Find 6 of our favorites below. Click the titles to read the full CDC reports.
Community water systems in the United States use one of three additives for water fluoridation. Decisions on which additive to use are based on cost of product, product-handling requirements, space availability, and equipment.
These statistics were prepared using water system data reported by states to the CDC Water Fluoridation Reporting System as of December 31, 2012, and the US Census Bureau state population estimates for 2012.

Fluoridation is the single most important commitment a community can make to its children and to future generations
With the development of fluoridated drinking water and dental sealants, Americans are less likely to experience tooth loss and gingivitis by middle age … Community water fluoridation continues to be a vital, cost-effective method of preventing dental [cavities].
Water fluoridation has helped improve the quality of life in the United States by reducing pain and suffering related to tooth decay, time lost from school and work, and money spent to restore, remove or replace decayed teeth.”

We continuously add links to the latest research concerning fluoridation.
Breastfeeding is important for health and development. Yet, the interaction between breastfeeding duration and usage of fluoridated water on caries experience has not been investigated. This study examined exposure to fluoridation as an effect modifier of the association between breastfeeding duration and caries. The 2012 to 2014 national population-based study of Australian children involved parental questionnaires and oral epidemiological assessment. Children were grouped by parent-reported breastfeeding duration into minimal (none or <1 mo), breastfed for 1 to <6 mo, breastfed for 6 to 24 mo, and sustained (>24 mo). Residential history and main water source used for the first 2 y of life were collected to group children into exposed (WF) and nonexposed (NF) to fluoridation. Socioeconomic status, infant formula feeding, and sugar-sweetened beverage (SSB) consumption data were collected.
These results expand our understanding of caries epidemiology under CWF cessation conditions and reaffirm that optimal CWF exposure prevents dental decay. These findings can offer fiscal estimates of the cost burden associated with CWF cessation policies and help decision-makers advance oral health, prevent dental caries, and promote equity in oral health outcomes.
