Growth of Community Water Fluoridation (1940 to 2002)

Community water fluoridation began in the 1940s. Since then the number of community water systems and the number of people served by fluoridated systems have been steadily increasing. Currently about two-thirds of the US population receives fluoride through their community water system. This has been an important factor in the steady decrease in tooth decay rates.
