A long-term study tracking more than 10,000 individuals over several decades found no evidence that fluoride negatively impacts brain function. Researchers examined cognitive performance and neurological health across diverse populations, concluding that exposure to fluoride through drinking water and dental products does not impair mental abilities or contribute to neurodevelopmental issues. The findings challenge previous concerns about fluoride's role in cognitive decline and support its continued use in public health initiatives.
The study adds significant weight to the scientific consensus on fluoride safety, particularly in community water supplies. Results were consistent across age groups, genders, and regions, reinforcing the reliability of the data. These outcomes are expected to inform ongoing public health discussions and policy decisions related to water fluoridation.
