Your oral health may affect your heart health.

The Connection Between Oral Health and Heart Health

Mouth germs and gum inflammation can enter the bloodstream and is linked to inflammation in the body. Gum disease is linked to higher risk for heart and blood vessel disease and high blood pressure. Your dental team can help you take the next step. Along with caring for your teeth and gums, they may check your blood pressure to help you stay informed about your health.

Your Questions About Oral and Heart Health Answered

Understanding the Connection
How are oral and heart health connected?
Research has found a connection between gum disease and heart disease, which affects the heart and blood vessels. Gum disease cause inflammation in your gums, and bacteria from the mouth can sometimes enter the bloodstream. Taking care of your teeth and gums is an important part of caring for your overall health. Brush twice a day, clean between your teeth daily, and keep up with recommended dental visits.
Can gum disease cause heart disease, a heart attack or strokes?
Studies show that people with gum disease have a higher risk of cardiovascular problems, including heart attack and stroke. However, research has not proven that gum disease directly causes these conditions. Gum disease and heart disease also share risk factors, including tobacco use and diabetes. If you have gum disease or concerns about your heart health, talk with your dental and medical care teams about ways to manage your risks.
Does treating gum disease prevent heart attacks, or strokes?

There is not enough evidence to show that treating gum disease prevents heart attacks and strokes. However, treating gum disease can improve hum health and may reduce some signs of inflammation in the body.

Treating gum disease remains important for protecting your teeth and gums. Ask your dental team about treatment options and continue following your medical care team's recommendations for cardiovascular health.

Which tooth is connected to the heart?
No single tooth is connected to the heart. The connection is about oral health, not one tooth.
What It Means for Your Health
Is gum disease connected to high blood pressure?

Research has found an association between gum disease and high blood pressure, also called hypertension. Some studies suggest that treating gum disease may modestly improve blood pressure in certain people, but more research is needed.

Gum disease treatment does not replace blood pressure care. Know your blood pressure numbers, follow your medical care team's recommendations, and talk with your dentist about your gum health.

Can a tooth infection affect my heart?

In rare cases, bacteria from the mouth can enter the bloodstream and cause a serious infection of the heart's inner lining or valves, called infective endocarditis. People with certain conditions are at greater risk.

Most tooth infections do not cause heart infections, but they still need prompt dental care. Contact your dentist if you have signs of a tooth infection, such as pain, swelling, or fever, and tell your dental team about any heart conditions you have.

What should I do if my gums bleed when I floss or brush my teeth?
Bleeding gums can be a sign of inflammation or gum disease, especially if the bleeding happens regularly. Brushing too hard or starting a new flossing routine can also irritate your gums. Continue brushing gently with a soft-bristled toothbrush and cleaning between your teeth daily. If bleeding continues, make an appointment with your dentist to find out what's causing it.
Take the Next Step
Why does my dentist check my blood pressure?

Your dentist may check your blood pressure because it provides important information about your overall health and can help your dental team plan safe care. High blood pressure often has no symptoms, so a dental visit may be an opportunity to identify a reading that needs follow-up

A single high reading does not necessarily mean you have high blood pressure. Ask your dental team what your numbers and whether you should follow up with your medical care team.

What can I do to care for my mouth and heart?

Healthy daily habits can support both oral health and cardiovascular health. Brushing twice a day with fluoride toothpaste, cleaning between your teeth daily, eating a healthy diet, avoiding tobacco, and keeping recommended dental appointments can help protect your health.

Share your health conditions, medications, and any changes in your health with your dental and medical care teams. Start with one habit you can work on today and ask your care team what else may be helpful for you.
