Recommended fluoride levels revised
Feds recalibrate optimal fluoridation level, support continued use
The Health and Human Services Department has announced it is recalibrating the recommended ratio of fluoride to water that is considered optimal for fluoridating community water systems.
The new recommendation for optimally fluoridated water is 0.7 parts per million, compared to the previous level of 0.7 to 1.2 parts per million. The adjustment will provide an effective level of fluoride to reduce the incidence of tooth decay, while minimizing the rate of fluorosis in the general population.
In addition, the Environmental Protection Agency is initiating a review of the maximum allowable level of fluoride in drinking water, which is currently 4 parts per million. In California, current regulations put the maximum allowable level of fluoride at 2 parts per million.
While the action may prompt questions, dentists can reassure patients that the government is stressing that water fluoridation is a very safe and effective way to prevent dental disease.
The Centers for Disease Control and Prevention has more information on the announcement.
