The Camas City Council is set to reconsider the City’s nearly 60-year-old practice of fluoridating its public water supply. Last week, a group of concerned community members — some from Camas but most from outside the CIty — implored Camas officials to halt the fluoridation practice that has been touted by medical professionals for decades as a cost-effective way to prevent tooth cavities.
The speakers had some valid points. Although dentistry groups, as well as the U.S. Surgeon General and Centers for Disease Control (CDC) have long recommended fluoridating water systems as a preventative measure that costs far less than having to repair dental cavities, there have always been concerns about the possible negative health and environmental impacts of adding fluoride — an inorganic ion of fluorine, a naturally occurring mineral found in the Earth’s crust — to our public water supplies.
In 2016, concerned that some pregnant women and children may be ingesting more fluoride than they need to keep teeth from developing cavities, the National Toxicology Program began a systemic review of peer-reviewed scientific literature about the “association between fluoride exposure and neurodevelopment and cognition.”
Their findings concluded that “higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children.” The review also concluded, however, that there was “insufficient data to determine if the low fluoride level” — such as the 0.7 milligrams per liter currently used in Camas and most other municipalities in the United States that fluoridate their water systems — “has a negative effect on children’s IQ” and “found no evidence that fluoride exposure had adverse effects on adult cognition.”
City leaders should be willing to have an open debate about the process of fluoridating drinking water, but it is hard to understand why community members, as well as public officials, can be so concerned by fluoride, which has not been definitely proven to be harmful to children’s health in the small doses available in drinking water, when they have been so silent about preventing the spread of a severe acute respiratory syndrome (SARS) virus known as COVID — one of the greatest public health threats of the past century.
