Could Gum Disease and Memory Loss Be Related?

At Dental Center of Lufkin, we care about your dental health and want you to know about new research that may link gum disease to memory loss as the same bacteria found in mouths with poor gum health has been found in the brains of those who suffer from Alzheimer’s disease. While scientists are still studying this topic, here are two important pieces of research explained in simple terms:

1. A Bacteria Called Porphyromonas gingivalis and Alzheimer’s

A study by Dominy and colleagues (2019) found that a bacteria known as Porphyromonas gingivalis—commonly found in people with gum disease—was also present in the brains of some Alzheimer’s patients. This suggests that the bacteria, or the chemicals it produces, might play a role in causing brain inflammation that could contribute to Alzheimer’s. Read more about the study here.

2. Gum Disease and Memory Loss: What the Research Says

Other research, including a review of several studies available on PubMed, has found that people with long-term gum problems might have a higher risk of memory issues and other signs of Alzheimer’s. This review looked at many studies and found a possible connection between long-lasting gum inflammation and changes in the brain that are related to Alzheimer’s. Check out the review on PubMed.

What Does This Mean for You?

Even though these studies do not prove that gum disease causes Alzheimer’s, they highlight the importance of taking care of your mouth. Good oral care—like regular brushing, flossing, and dental check-ups—helps keep your gums and teeth healthy and may also support your overall well-being.
