Texas Attorney General Ken Paxton is investigating two leading toothpaste makers over their use of fluoride, suggesting that they are “illegally marketing” the teeth cleaners to parents and kids “in ways that are misleading, deceptive, and dangerous.”
The toothpaste makers in the crosshairs are Colgate-Palmolive Company, maker of Colgate toothpastes, and Proctor & Gamble Manufacturing Co., which makes Crest toothpastes. In an announcement Thursday, Paxton said he has sent Civil Investigative Demands (CIDs) to the companies.
The move is an escalation in an ongoing battle over fluoride, which effectively prevents dental cavities and improves oral health. Community water fluoridation has been hailed by health and dental experts as one of the top 10 great public health interventions for advancing oral health across communities, regardless of age, education, or income. But, despite the success, fluoride has always had detractors—from conspiracy theorists in the past suggesting the naturally occurring mineral is a form of communist mind control, to more recent times, in which low-quality, controversial studies have suggested that high doses may lower IQ in children.
The debate was renewed earlier this year when the National Toxicology Program at the National Institute of Environmental Health Sciences finally published a particularly contentious study after years of failed scientific reviews. The study claims to find a link between high levels of fluoride exposure and slightly lower IQs in children living in areas outside the US, mostly in China and India. But the study’s methodology, statistical rigor, risk of bias, and lack of data transparency continue to draw criticism.
