Good dental hygiene isn’t just about a clean, healthy smile, it’s also an important way to protect your overall well-being. A growing body of research shows that what happens in your mouth can influence the rest of your health, including your heart.

When your teeth and gums are cared for, your whole system benefits. But when oral health is neglected, harmful bacteria and inflammation can spread beyond the mouth, potentially harming cardiovascular health over time.

 

Your smile and your heart 

How can bacteria from your mouth cause problems in other parts of your body? Here’s one way:

 

checkmark Poor oral hygiene allows harmful bacteria to thrive in the mouth.

checkmark These bacteria can trigger inflammation in the gums, and the effects of that inflammation can lead to problems in your bloodstream.

checkmark This can then contribute to damage to your blood vessel walls, raising your risk of heart attack or stroke. 

 

Daily habits for oral and cardiovascular health

Protecting yourself from this increased risk is as simple as incorporating smile-friendly habits into your daily routine. For example:

 

checkmark Brush and floss daily. Remove plaque and reduce gum inflammation by brushing twice a day and flossing once daily. 

checkmark Keep regular dental visits. Professional cleanings and exams can help catch early signs of gum disease or inflammation that may be linked to heart disease.

checkmark Practice heart-healthy habits. Eat a balanced diet, stay active, and avoid smoking to support both oral and cardiovascular wellness.

 

This advice is backed by research — studies have shown that people who brush their teeth more frequently and have regular dental cleanings have lower odds of cardiovascular events compared with those who don’t.

 

Clean mouth, healthier heart 

Your oral and cardiovascular health are impossible to separate. That’s why treating your teeth and gums well isn’t just good for your smile, it’s good for your heart, too.
