A groundbreaking randomized trial in Kinston, North Carolina is testing fluoridated vs. non-fluoridated water in young children to produce the most rigorous evidence yet on fluoride’s real-world benefits today.  

00:00 Intro
01:01 Quick history setup: how fluoridation began and why it became widespread.
01:20 Early clues: mottled teeth but fewer cavities; investigators suspect water.
01:40 Fluoride identified in water; dental fluorosis linked to high levels.
02:13 Grand Rapids becomes first to fluoridate; endorsements follow.
02:38 UNC dentistry expertise and an under-the-radar, ongoing study.
03:33 Kinston removes fluoride—setting up the WaterBeST Treatment Study.
03:52 Observational vs. randomized research and why randomization matters.
04:31 Study design: 200 families, blinded fluoridated vs. non-fluoridated bottled water.
04:53 Measuring total fluoride exposure via toenail clippings.
05:21 Potential expanded outcomes (e.g., IQ) if funded; results expected 2029.
06:34 How fluoride’s cavity-prevention benefit has changed; biggest gains for low-income families.
