The AP reports a social media video “is cautioning users against going to dentists while baselessly asserting that dental products containing fluoride are unsafe.” In the video shared on Instagram, a man says, “They don’t know that fluoride is a neurotoxin that’s been directly linked to dementia and Alzheimer’s.” The article notes, “Experts say there is no research showing that topical products containing fluoride – such as toothpaste and mouthwash – cause dementia or Alzheimer’s.” The CDC’s Division of Oral Health said in a statement that the agency “is not aware of any study that purports to link use of topical fluoride products, when used appropriately, to any systemic health risk.”
