McKay also observed that teeth affected by this condition seemed to be less susceptible to dental caries. In 1931, Dr. H. Trendley Dean, U.S. Public Health Service Dental Officer, conducted pioneering research into the relationship between fluoride and dental caries. His research laid the groundwork for community water fluoridation in the United States. In 1945, Grand Rapids, Michigan, became the first city in the world to fluoridate its drinking water. This finding revolutionized dental care and resulted in tooth decay being preventable for most people.
Water fluoridation is relatively inexpensive in the United States.
The documented effectiveness of community water fluoridation in preventing dental caries prompted rapid adoption of this public health measure in cities throughout the United States. In the 1960s, the U.S. Public Health Service provided funding, technical expertise, and leadership to promote and establish fluoridation programs throughout the United States. The federal government continues to promote water fluoridation worldwide. You re not healthy without good oral health.
