Water Flouridation

Water fluoridation has been one of the WSDA’s core values, dating back to at least the 1950s, when communities began adding fluoride to public water supplies to reduce cavities. And yet, Washington is one 16 states nationwide with fluoridation rates less than 62 percent. Only about 59 percent of people here are on fluoridated community water systems, according to the state's Department of Health. 

Across the nation, community water fluoridation is supported as an economical public health measure that prevents tooth decay, particularly among those at greatest risk.  Recently, the national Council of State Governments passed a resolution in support of community water fluoridation.  Communities that optimally fluoridate their water supply see significant cost savings.  Recently, a group of researchers conducted a cost and savings analysis of community water fluoridation programs in Colorado and concluded that "Colorado realizes significant annual savings from community water fluoridation; additional savings and reductions in morbidity could be achieved if fluoridation programs were implemented in other areas."

Community water fluoridation receives strong support from Washington policy makers.  Recently, the Department of Health re-issued a statement  in support of water fluoridation as a sound population-based public health measure.  The Department of Health continues to support Washington communities in their efforts to fluoridate community water supplies. Currently, 45 municipalities in Washington optimally fluoridate their water.
