Water Fluoridation Data & Statistics
As part of an overall strategy to use public health interventions to reduce or prevent disease among individuals and communities, the US Department of Health and Human Services has set a national health objective for community water fluoridation.
CDC monitors the progress of the nation and individual states toward meeting the Healthy People 2020 objectiveexternal icon on community water fluoridation—that 79.6% of people served by community water systems will receive water that has the optimum level of fluoride recommended for preventing tooth decay.
In 2018, 73.0% of the US population on community water systems, or 207,426,535 people, had access to fluoridated water.
Fluoridation Statistics State-reported data on fluoridated water systems are linked to Census data to create national fluoridation statistics. View the most recent reports.

Water Fluoridation Reporting System (WFRS)
WFRS is a water fluoridation monitoring data system for state and tribal water fluoridation program managers and oral health program directors or managers. Data from WFRS are summarized in the biennial report of national and state fluoridation statistics.
Other data sources are available in Oral Health Data Tools.
