A Drop in the Bucket (USPHS, 1952)
This film tells the story of how one community brought the benefits of fluoridated water to its children, how the dentists, the health officers, the mayor, the waterworks engineer, and citizens got together and fought for fluoridation before it was the widely recognized public health measure it is today. Based in part on the story of how the people of Newark, Delaware added fluoride to their water supply, the film vividly portrays the down-to-earth situations that exist in every community, the typical conflicts, the doubts about fluoridation, and the evidence for it.
