How Oral Health Affects Brain Health: What the Science Says

Many people think oral health only affects the mouth. But science shows that poor oral health may also affect the brain. A recent study shows that gum disease and tooth loss can lead to memory loss and lower brain volume.

What the Study on Oral Health Found

Researchers looked at brain scans and dental records from over 50,000 people. They found that people with gum disease had less grey matter in parts of the brain linked to memory and learning. This was true even in younger adults.

Tooth loss also made a difference. People who had fewer teeth had more shrinkage in the brain. The more teeth lost, the greater the change.

These brain changes can increase the risk of diseases like Alzheimer’s.

How Oral Health and Brain Health Are Linked

Here are three reasons why bad oral health might affect the brain:

  1. Inflammation: Gum disease causes swelling and infection. This can spread through the blood and harm brain tissue.

  2. Bacteria: Harmful mouth bacteria can travel to the brain and cause damage.

  3. Chewing: Losing teeth makes it harder to chew. Less chewing may reduce blood flow and activity in the brain.

What You Can Do to Protect Both

Improving oral health may help protect your brain. Start with simple daily habits:

  • Brush twice a day with toothpaste.

  • Floss every day.

  • Visit your dentist regularly.

  • Treat gum problems early.

  • Replace missing teeth.

Good oral care is not just about your smile. It is also about your long-term health.
