The number of communities and people who benefit from community water
fluoridation is continuing to increase. This effective public health
intervention to reduce tooth decay and promote good oral health was
begun in 1945. In 2010, 73.9% of the U.S. population on community water
systems, or about 204.3 million people, had access to fluoridated water.
CDC monitors the progress of the United States and individual
states toward meeting the Healthy People 2020 objective on community
water fluoridation—that 79.6% of people on community water systems will
receive water that has the optimal level of fluoride recommended for
preventing tooth decay.
National Oral Health
Surveillance System (NOHSS)
NOHSS provides national and state statistics on water fluoridation for
1992, 2000, 2002, 2004, and 2006. This information is available in
tables, graphs, maps, and state profiles. Long-term trends in national
water fluoridation statistics are also presented in a graph and table.
Synopses of State and Territorial Dental Public Health Programs
Synopses presents biennially reported water fluoridation statistics in
the context of annually reported state oral health program information.
Footnotes specify the time period and data source for water fluoridation
and other state program statistics presented in the Synopses.
Oral Health Maps
This resource provides national and state fluoridation statistics for
1992, 2000, 2002, 2004, and 2006. It also generates state and county
fluoridation statistics from the most current data available in the
Water Fluoridation Reporting System (WFRS) for the states that have
approved this use of their WFRS data.
MWF allows consumers in states participating in the CDC
water fluoridation data systems to learn basic information about
their water system.
This fact sheet describes the methodology used by state drinking water
programs, EPA, and CDC to estimate the number of people served by water
systems, the number of people receiving fluoridated water, and the Healthy
People objective for water fluoridation.
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.
