A large-scale study published in the Proceedings of the National Academy of Sciences confirms that fluoridated drinking water does not negatively impact children’s IQ or adult cognitive function.
Researchers analyzed decades of data from over 10,000 participants and found no difference in brain health between those with and without fluoride exposure.
Experts emphasize that community water fluoridation remains a vital tool for preventing tooth decay and supporting overall wellness across all age groups.
Maintaining dental health is essential as it directly influences heart health, respiratory function, and diabetes management.
“We find no evidence that community water fluoridation is negatively associated with adolescent IQ or adult cognitive functioning,” the study authors wrote.
To protect your smile, experts suggest brushing twice daily with fluoride toothpaste, limiting sugary snacks, and visiting a dentist annually for check-ups.
Following these proactive steps ensures that your oral health supports a vibrant and healthy lifestyle as you age.
