Your mouth isn’t just the start of your digestive system; it’s a thriving ecosystem of bacteria with direct access to your bloodstream.

When gums are inflamed, as happens in gum disease (periodontitis), the barrier that normally protects your body from oral bacteria weakens. This allows bacteria and inflammatory molecules to enter the bloodstream.

Once these invaders circulate, they can affect the lining of your blood vessels, leading to what doctors call endothelial dysfunction – a key step in the buildup of arterial plaque.

Chronic, low-level inflammation is now recognised as a major driver of heart disease, and persistent gum infections can fuel this process. In other words, gum disease may do more than coexist with heart disease; it may actively contribute to it.

Studies consistently show a link between gum disease and cardiovascular problems.

People with periodontitis have higher risks of high blood pressure, heart failure and unhealthy cholesterol levels, even when factors like smoking and diabetes are accounted for.

Some large observational studies suggest that severe gum disease is associated with a significantly increased risk of cardiovascular events.Inflammation plays a central role.

Gum disease causes a steady rise in inflammatory molecules that are known to damage blood vessels. Even more striking, certain oral bacteria have been found inside arterial plaques, where they can accelerate plaque formation and raise the risk of heart attack or stroke.

Oral health should not be excluded from general healthcare. Greater integration between dental and medical prevention strategies could help reduce the long-term burden of chronic disease.

In short, protecting your heart may start with protecting your smile.
