From the moment I saw the study — and editorial and editor’s note — among JAMA’s embargoed studies, I knew it would be a doozy. Certain topics arouse controversy simply by their existence, and water fluoridation is very high on that list.

So when I was assigned to write about the JAMA Pediatrics study (Reminder: AHCJ members get free access to the JAMA Network.)  finding a link between prenatal fluoride exposure and reduced IQ in preschoolers, two things went through my mind: One, this is going to be covered horribly by some outlets and likely create unnecessary anxiety among parents, especially pregnant women (who have enough to worry about when it comes to do’s and don’ts).
