From 1959-1970, the communities of Saint Louis, Missouri were tasked with a unique mission: sending in the teeth of children to a newly formed initiative called the Baby Tooth Survey. Founded by physicians Louise and Eric Reiss, this project was in collaboration with Saint Louis University and the Washington University of Dental Medicine with the primary goal of proving the traces of radioactive contamination within children’s bodies. This radiation was caused by hundreds of atmospheric nuclear tests conducted by the U.S. government in Nevada, New Mexico, and the Marshall Islands. Strontium-90, one particularly harmful radioactive isotope, was contaminating water and dairy in the United States, thereby polluting milk products being consumed by children which would be absorbed into bones and teeth. The indisputable findings of harmful radioactive levels in children documented by this initiative led President John F. Kennedy to sign the Partial Test Ban Treaty in 1963, which banned all nuclear tests except those detonated underground. This harrowing narrative led by housewives and mothers plays an important role in the history of anti-nuclear activism, which is captured by director Hideaki Ito in his documentary film Silent Fallout: Baby Teeth Speak (2023).
