🧠 Oral Bacteria Linked to Alzheimer’s Disease
The Mouth–Brain Connection
A 2020 study published in Frontiers in Cellular and Infection Microbiology found something surprising: the same bacteria that cause gum disease were discovered in the brains of people with Alzheimer’s disease.
The bacteria, called Porphyromonas gingivalis (P. gingivalis), release toxins that can damage brain cells and trigger inflammation. Over time, that inflammation may play a role in memory loss and Alzheimer’s disease.

What This Means
Gum disease isn’t just a mouth problem — it’s an infection. When harmful bacteria live under the gums, they can enter the bloodstream and travel to other parts of the body, including the brain.
Researchers believe this mouth-to-brain connection may be one reason why people with long-term gum infections have a higher risk for Alzheimer’s disease.
How to Catch These Bacteria Early
With the MicrobeLink Dx’s 11-Microbes Test, dental providers can find out if high-risk bacteria like P. gingivalis are active in your mouth.
This simple test uses paper points to collect bacteria from the base of the gums — where infection starts. Detecting the bacteria early allows for targeted treatment before they spread.
Protecting More Than Your Smile
Healthy gums don’t just help your teeth — they may also help protect your brain, heart, and overall health.
