Researchers are increasingly exploring how problems in the mouth, such as gum disease and chronic inflammation, might influence brain health. Certain oral bacteria and inflammatory signals may enter the bloodstream and potentially contribute to processes linked with cognitive decline, though the science is still developing and doesn’t prove cause-and-effect. What’s clear is that good oral hygiene is a low-risk, high-reward habit. Brush gently with fluoride toothpaste, floss daily, clean your tongue, and keep up with regular dental visits.
