Leaded gasoline, paint, and pipes left a toxic fingerprint in the baby teeth of half of all Americans — and those tiny clues reveal how silent doses of lead rewired IQ scores, crime rates, and mental health for decades. In this Howtown episode we laser‑scan my own baby teeth with “tooth detective” Manish Arora, revisit Herbert Needleman’s 1970s Boston study, and track economist Jessica Reyes’s state‑by‑state link between tetraethyl lead’s phase‑out and the 1990s crime drop. New data from New Zealand’s Dunedin Study (analyzed by Aaron Reuben) show how early exposure still shapes Gen X brains, personalities, and social mobility, framing one of the largest environmental injustices in U.S. history.
