Fluoride in Drinking Water

According to the Centers for Disease Control and Prevention (CDC), 67% of the 246 million people in the United States who receive their water from a public water system received fluoridated water in 2000. One of the CDC's national health goals is to increase the proportion of the U.S. population served by community water systems with "optimally" fluoridated drinking water to 75% by 2010. The decision to add fluoride to a water supply is made by local or state governments. The U.S. Public Health Service (PHS) has recommended an optimal fluoridation level in the range of 0.7 to 1.2 milligrams per liter (mg/L) for the prevention of tooth decay.
