Scientists are beginning to suspect that Alzheimer’s disease might not only be a problem of aging brains — it could actually start in an unexpected place: the mouth. Emerging studies point to chronic gum disease as a possible trigger for a chain reaction leading to Alzheimer’s.

In a landmark 2019 study, researchers at the University of Louisville discovered Porphyromonas gingivalis — the bacteria responsible for long-term gum infections — inside the brains of people who had died with Alzheimer’s. Even more concerning, they also found toxic enzymes from these bacteria in the brains of people who had never shown dementia symptoms, suggesting the damage might have begun years before any memory problems appeared.

When scientists infected mice with this gum bacteria, it didn’t remain in their mouths — it traveled to the brain, increased the levels of amyloid-beta proteins linked to Alzheimer’s, and triggered inflammation. They also tested a new drug, COR388, which lowered the amount of bacteria in the brain and reduced amyloid buildup in mice — an early sign that this approach might help slow or even prevent Alzheimer’s.

Although experts caution that it’s still too soon to say gum disease directly causes Alzheimer’s, the findings are significant. They challenge the long-held belief that dementia leads to poor oral health — instead, oral bacteria may be quietly entering the brain and causing damage long before memory loss begins.
