US CDC has recognized community water fluoridation as one of the 10 public health achievements of the 20th century. Fluoridation is a cost effective community heath measure for all regardless of education, socioeconomic status, or access to dental care.
The Pew Charitable Trust Foundation has developed an interactive map to show the percentage of residents served by public water systems in each state who are receiving fluoridated water.
