In 1945 Grand Rapids, Michigan became the first city in the world to adjust the level of fluoride in its water supply to prevent tooth decay for its citizens. Since that time, fluoridation has dramatically improved the oral health of tens of millions of Americans. Community water fluoridation is the single most effective public health measure to prevent tooth decay. The Centers for Disease Control and Prevention has proclaimed community water fluoridation as one of 10 great public health achievements of the 20th century.
Studies have consistently shown that fluoridation of community water supplies is safe and effective in preventing dental decay in both children and adults by at least 25%. Approximately 74.6% of the U.S. population served by public water systems receive the benefit of optimally fluoridated water. Simply by drinking water, Americans benefit from fluoridation's cavity protection whether they are at home, work or school.
