As a family doctor I believes that good health starts with the basics—what we eat, how we move, and yes, how we care for our teeth and gums. I ask every patient at their wellness visit who they see for their eye and dental care. The mouth is important. (And, who wants to go blind?!)

You may not realize it, but the health of your mouth can have a major impact on your heart and your blood sugar. Scientists have found strong links between gum disease and serious conditions such as heart disease, stroke, and diabetes.

What the Research Shows

A recent study found that people with gum disease and cavities had an 86 percent higher risk of stroke. Even those with gum disease alone were 44 percent more likely to have a stroke.

Large studies involving millions of people have found the same pattern. People with gum disease have about a 24 percent higher risk of serious heart problems such as heart attack or stroke, and a 31 percent higher chance of dying early from any cause.

These findings tell us that brushing, flossing, and seeing your dentist regularly are not just about keeping a bright smile—they can truly help save your life.

Why Gum Health Matters

Your gums are filled with tiny blood vessels. When gums become infected or swollen, germs and inflammation can enter the bloodstream. This can damage blood vessels, increase blood pressure, and make blood clots more likely—all of which raise the chances of heart attack and stroke.

Gum disease and diabetes also affect each other in both directions. People with diabetes are two to three times more likely to develop gum disease, and gum infections can make blood sugar harder to control. Treating gum disease can even lower blood sugar by about 0.3 to 0.4 percent, which makes a meaningful difference over time.

How to Keep Your Mouth and Body Healthy

1. Brush twice a day with fluoride toothpaste.
2. Floss daily to remove plaque between teeth.
3. Visit your dentist at least twice a year.
4. Do not smoke or vape; both damage gums and blood vessels.
5. Eat plenty of fruits, vegetables, and whole grains while limiting sugar.
6. If you have diabetes, keep your blood sugar under control and tell your dentist.
