The overwhelming weight of scientific evidence supports the safety of community water fluoridation.
There is a clear commitment on the part of the public health community to continue to monitor the
safety of community water fluoridation.
18. Are additional studies being conducted to determine the effects
of fluorides on humans?
Answer
Yes. Since its inception, fluoridation has undergone a nearly continuous process of re-evaluation.
As with other areas of science, additional studies on the effects of fluorides on humans can provide
insight as to how to make effective choices for the use of fluoride. The ADA and the USPHS support
this ongoing research.
Fact
For more than 80 years, detailed reports have been published on multiple aspects of fluoridation.
The accumulated dental, medical, and public health evidence concerning fluoridation has been reviewed
and evaluated numerous times by academicians, committees of experts, special councils of governments,
and most of the world’s major national and international health organizations. The consensus of the
scientific community is that water fluoridation, at the level recommended to prevent tooth decay,
safely provides oral health benefits, which in turn support improved general health. The question of
