Fluoridation in public water supplies is currently a contentious issue across the United States and parts of the UK. In Hillsboro, Oregon, a ballot measure to fluoridate water was rejected by 57% of voters, despite support from various health organizations and officials. Meanwhile, the Trump administration may consider removing fluoride from drinking water, influenced by Robert F. Kennedy Jr.'s claims regarding its risks, although such claims have been refuted by the CDC. In Cornwall, UK, council members are divided on the issue due to public opposition, despite recognition of its dental health benefits. In Wisconsin, several communities have ceased water fluoridation, partially due to a federal judge's order for stricter EPA regulations after concerns about fluoride's impact on children's intellectual development. Additionally, residents in Durango, Colorado, expressed concerns following a court ruling questioning fluoride's safety, although the city has not yet taken action to remove it.
