In recent years, researchers have uncovered mounting evidence that poor oral hygiene can do more than damage your teeth and gums—it may also affect how your brain functions. This connection, known as the “mouth-brain link,” is gaining increasing attention in medical and dental communities.

The Role of Inflammation

One of the key factors behind the mouth-brain connection is inflammation. Periodontal disease, a common result of poor oral hygiene, causes chronic inflammation in the gums. This inflammation doesn’t just stay in your mouth. Bacteria and inflammatory molecules can enter the bloodstream and travel throughout the body, including the brain. Chronic inflammation is known to be a risk factor for cognitive decline and diseases such as Alzheimer’s and dementia.
