Fluoridation is considered beneficial by the overwhelming majority of the health and
scientific communities, as well as the general public.
Fluoride helps prevent tooth decay.
All ground and surface water in the United States contains some naturally
occurring fluoride. If a community's water supply has a low natural
(less than 0.7 parts per million), fluoridation adjusts the level of
fluoride to the optimum level for protecting teeth against decay (0.7–1.2 parts per million).
View the following for fluoridation status data:
- Public Water Supply
Percentage of the U.S. population on Public Water
Systems receiving fluoridated water. A public
water system provides water for human consumption to the public
through a system of pipes.
- Fluoridation Growth
Fluoridation Growth, by the U.S. Population, 1945–2006.
Fluoridation of community water supplies in the United States has grown from 230,000 people
in 1945 to more than 184 million people in 2006.
