Increased levels of fluoride in pregnant moms, even from drinking water, may be associated with a lower IQ in their children, a new study finds
Water fluoridation has been hailed by the US Centers for Disease Control and Prevention as one of the top great public health achievements of the 20th century, but a new study raises questions about its role as a potential neurotoxin in utero.
The study, published in the journal JAMA Pediatrics on Monday, found that increased levels of fluoride exposure during pregnancy were associated with declines in IQ in children. Previous research has made similar findings, but this is the first such study to evaluate the effect of fluoride on populations receiving what the US Public Health Service considers optimal levels of 0.7 milligrams of fluoride per liter of drinking water, such as in the United States and Canada.
In an email to CNN, Dr. Pamela Den Besten, a professor in the University of California San Francisco's School of Dentistry, said,"Fluoride remains a safe and effective tool for caries prevention." Den Besten has studied the role of fluoride in fluorosis, a condition that results from excess exposure to fluoride.
