“The nationwide goal to prevent cavities through community water fluoridation is similar to previous public health efforts to prevent other common health problems. These include adding iodide to salt to prevent thyroid problems, adding iron to infant formula to prevent anemia, adding Vitamin D to milk to prevent rickets, adding niacin to flour and other foods to prevent pellagra, and adding folic acid to cereal grains products to prevent birth defects.”
“Each of these public health efforts represents situations where a nutritional additive is provided to everyone or to large target populations since it is impossible to individually identify and effectively treat the significant number of people who are at risk.”
