Dentists and doctors are often viewed as separate healthcare providers, but a growing body of evidence shows that oral health is deeply connected to overall health, particularly cardiovascular health. The American Heart Association's Healthy Smiles, Healthy Hearts initiative, in collaboration with Delta Dental of California, is working to bridge this gap by encouraging dental teams to take a total-body approach with their patients.
At the core of this connection is inflammation. When gums are inflamed, bacteria can travel from the mouth through the bloodstream, potentially causing blood vessels to constrict or become blocked. This can force the heart to work harder and raise blood pressure, increasing the risk of heart disease and stroke. According to the American Heart Association, more than 46% of U.S. adults have high blood pressure, and more than 40% of adults aged 30 and older are affected by periodontal (gum) disease.
To address these intertwined issues, the initiative promotes simple steps like blood pressure screenings during dental checkups. If a dental care team member pulls out a blood pressure cuff at your next appointment, it's a positive sign of integrated care. "The mouth is a gateway to the body and can often reveal more about your total body health than you may think," said Daniel Croley, D.M.D., chief dental officer at Delta Dental of California and Affiliates. "Oral health professionals have a powerful opportunity to integrate more into their patients' collective health care team beyond protecting their patients' teeth. By connecting oral health and heart health, this initiative helps dentists identify risks early and guide patients toward care that can improve and even save lives."
For individuals looking to protect both their teeth and their heart, experts from the American Heart Association offer four practical tips. First, follow a consistent brushing and flossing schedule: brush at least twice a day and floss at least once a day to disrupt plaque-forming bacteria. Use fluoride toothpaste and brush gently to avoid enamel wear and gum recession. Second, eat a healthy diet and limit sugar. Sugar feeds harmful oral bacteria, producing acid that causes cavities and gum disease. Prioritize vegetables, lean proteins, complex carbohydrates, and healthy fats while limiting added sugars and refined carbs. Third, avoid smoking and tobacco products. Smoking significantly increases the risk of periodontal disease, tooth loss, and oral cancer, and other forms of tobacco like vaping and chewing can harm dental health by drying out the mouth and restricting blood flow to the gums. Quitting benefits both oral and heart health. Fourth, communicate with your healthcare team. Talk to your dentist about your blood pressure and your doctor about your oral health. Share your medical history, discuss medication side effects, and ask for personalized recommendations. To learn more about improving oral and cardiovascular health, visit Heart.org/OralHealth.
This initiative matters because it underscores a paradigm shift in healthcare: the mouth is not isolated from the rest of the body. By integrating dental and medical care, healthcare providers can detect risks earlier, prevent complications, and ultimately save lives. With millions of Americans affected by gum disease and high blood pressure, the collaboration between the American Heart Association and Delta Dental of California represents a vital step toward holistic health management. As research continues to reveal the mechanisms linking oral inflammation to cardiovascular disease, patients and providers alike are encouraged to adopt a total-body perspective, recognizing that a healthy smile is a key component of a healthy heart.
