Claims supported
Reviewed claim cards that cite this source in the evidence graph.
fluoride: Total fluoride exposure matters more than a single source
Total fluoride exposure matters more than a single source because water, toothpaste swallowing, infant formula mixing, tea, supplements, foods, and groundwater can add together.
fluoride: The strongest fluoride neurodevelopment concern is dose-sensitive and concentrated
The strongest fluoride neurodevelopment concern is dose-sensitive and concentrated around higher total exposure, not a blanket proof that every fluoridated water system lowers IQ.
fluoride: Evidence is not strong enough to conclude that the
Evidence is not strong enough to conclude that the U.S. recommended community-water level around 0.7 mg/L causes lower IQ, even though higher-exposure findings justify scrutiny.
fluoride: Cancer is not the strongest current fluoride safety signal
Cancer is not the strongest current fluoride safety signal compared with dental fluorosis and neurodevelopment debates, so broad fluoride-cancer claims need specific endpoint evidence.
