The Arterial Plaque That Begins in Your Mouth

The dangerous plaque that clogs your arteries may have a surprising origin story: your mouth. Medical experts are highlighting the link between oral bacteria and atherosclerosis.
The key to this connection is inflammation. When dental plaque (a bacterial film) builds up, it causes chronic gum inflammation. This is often exacerbated by an old toothbrush that can no longer clean effectively.
This inflammation in the gums is a breach in your body’s defenses. It allows bacteria and inflammatory molecules to escape the mouth and enter the circulatory system.
Once in the blood, these agents can travel to the heart. They are believed to play a significant role in the formation of arterial plaque, the very substance that hardens and narrows arteries.
This is why people with untreated gum disease are at such a high risk for heart problems. To protect your arteries, start with your gums. The first rule: replace your toothbrush every three months.
