Can using fluoride cause dementia or memory loss?

Current research does not conclusively support a direct link between fluoride exposure and dementia or memory loss. While some studies have raised concerns about high levels of fluoride, particularly in children, the evidence remains inconclusive. Regulatory agencies, including the CDC and WHO, generally consider fluoride safe in the amounts used in dental care and community water fluoridation. Further research is needed to clarify any potential long-term effects of fluoride on cognitive health.
