At risk for heart disease? Your oral health matters.

When we think about heart health, we often focus on diet, exercise and genetics. One often-overlooked factor is oral hygiene. How well you care for your teeth and gums can make a difference in your overall and heart health. Emerging research suggests that poor oral health, especially gum disease, may contribute to cardiovascular (heart) disease.

Terry Norris, DMD, lead consulting dentist for HRI Dental & Vision, emphasizes the importance of oral health in overall wellness. He says, “What we know is that a variety of factors contribute to cardiovascular disease. Some of these are genetics, obesity, improper diet, sedentary lifestyle, stress and environmental factors. Oral health is one more piece of the puzzle.”

How Gum Disease Affects Cardiovascular Risk

Gum disease (periodontal disease) is a chronic inflammatory condition. It’s caused by bacterial infection of the tissues surrounding the teeth. These bacteria don’t just affect the mouth. They can enter the bloodstream and travel to other parts of the body, including the heart and blood vessels.

Once in the bloodstream, oral bacteria can trigger a cascade of harmful effects, stemming from bacterial toxins and inflammation.

Oral bacteria release toxins that damage the inner lining of blood vessels. This impairs the vessels’ ability to relax and contract properly. This leads to plaque buildup on the artery walls. Some oral bacteria can even cause platelets to clump together, potentially leading to blood clots.

The body’s immune response to oral bacteria leads to chronic, systemic inflammation, which can contribute to cardiovascular disease. The immune system may also become hypersensitive. It may react more aggressively to inflammation and worsen cardiovascular issues.

Comorbidities and Cardiovascular Risk

Gum disease has been linked to several cardiovascular conditions, including high blood pressure, atrial fibrillation (AFib), coronary artery disease and diabetes. Studies show that individuals who brush less frequently have a higher risk of cardiovascular events.

For example, developing research suggests that poor oral health may be connected to abdominal aortic aneurysms (AAA). AAA is a condition where the lower part of the aorta becomes enlarged and can rupture if left untreated.

Gum bacteria may contribute to inflammation in the aorta, weakening its walls. This increases the risk of bulging or swelling in the aorta. Having good oral hygiene may lower the risk for AAA.

Regular brushing, flossing and dental check-ups not only prevent cavities, they protect heart health.

Protect Your Heart Through Oral Health

Oral health is important for everyone, but is especially important for those at risk for cardiovascular disease.

Brush your teeth regularly. Floss every day. Visit the dentist for checkups and cleanings at least every six months. Get dental care for any oral health problems.

“Good oral hygiene is not just about dental health. It's an important part of overall health and can play a role in preventing heart disease,” Dr. Norris shares.

Flossing and Cardiovascular Events

While it may be tempting to skip out on flossing, its importance has been emphasized with recent research. 

The American Heart Association found that people who floss at least once a week had a 22% lower risk of ischemic stroke and a 44% lower risk of cardioembolic stroke. They also had a 12% lower risk of AFib compared to those who did not floss. These findings suggest that flossing may help reduce systemic inflammation, which is a known risk factor for cardiovascular events.

For individuals who struggle with traditional flossing, alternatives like water flossers can be effective. These tools help remove debris and plaque from between teeth and below the gumline.

Oral Hygiene for Heart Health

By following regular oral hygiene habits, you can lower your risk of gum disease. This can also help protect your heart and blood vessels. These simple habits of brushing, flossing and visiting the dentist are good for your smile and good for your heart.
