Utah Leads the Way: First State to Prohibit Fluoride in Public Water Systems

Utah has made history as the first U.S. state to ban fluoride from public drinking water. This law, signed by Governor Spencer Cox on March 27, will take effect on May 7. Fluoride has been used in U.S. water supplies since 1945 to help prevent cavities, but public opinion is shifting, with recent studies raising questions about its safety.

Concerns about fluoride began long ago but have gained traction lately. Influential voices, like Robert F. Kennedy Jr., now health secretary, have publicly supported removing fluoride from water systems. This aligns with a growing trend; anti-fluoridation bills have emerged in North Dakota, Tennessee, and Montana.

A significant worry is fluoride’s potential impact on children’s cognitive development. A recent review found that high levels of fluoride exposure, especially during pregnancy or early childhood, could correlate with lower IQs. However, experts like Dr. Scott Tomar, a public health dentist, suggest that the fluoride levels linked to these cognitive issues are much higher than what people typically encounter in fluoridated water.

Some individuals in the U.S. may be exposed to high fluoride levels naturally due to geological conditions, but Dr. Tomar argues that the risks associated with fluoridation itself have been overstated. He emphasizes that most communities don’t reach these harmful exposure levels through water fluoridation.

Interestingly, Governor Cox has not cited health risks as a reason for the ban. He claims that fluoride’s benefits for dental health in Utah have been minimal, with only 44% of residents drinking fluoridated water in 2022. He pointed out that even with half the population consuming fluoridated water and half not, there haven’t been significant differences in oral health outcomes.

As this debate unfolds, more research is likely needed to settle the ongoing concerns about fluoride. Meanwhile, public sentiment is swaying, influenced by the pandemic’s emphasis on personal health choices and skepticism toward government mandates.
