Dentists and doctors have traditionally been seen as separate healthcare providers, but a growing body of evidence shows that oral health and cardiovascular health are deeply interconnected. Inflammation is the common thread: when gums are inflamed, bacteria can enter the bloodstream and contribute to blood vessel constriction or blockage, forcing the heart to work harder and raising blood pressure. This raises the risk of heart disease and stroke.
The numbers are stark. More than 46% of U.S. adults have high blood pressure, and more than 40% of adults aged 30 and older have periodontal (gum) disease. To address this, the American Heart Association’s Healthy Smiles, Healthy Hearts initiative, in collaboration with Delta Dental of California, is encouraging dental teams to adopt a total-body perspective. Simple steps like blood pressure screenings during dental checkups can provide a more complete picture of a patient’s overall health.
“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 the public, the implications are clear: maintaining good oral hygiene is not just about saving teeth—it is a vital part of protecting your heart. Experts from the American Heart Association recommend a daily routine of brushing at least twice a day and flossing at least once a day to disrupt plaque-forming bacteria. Using fluoride toothpaste and brushing gently helps avoid enamel wear and gum recession.
Diet also plays a dual role. Sugar feeds harmful oral bacteria that produce acid, leading to cavities and gum disease, while also contributing to heart disease risk. A heart- and teeth-friendly diet emphasizes vegetables, lean proteins, complex carbohydrates, and healthy fats, while limiting added sugars and refined carbohydrates.
Avoiding smoking and tobacco products is equally important. Smokers face significantly higher risks of periodontal disease, tooth loss, and oral cancer. Vaping, dipping, and chewing tobacco also harm dental health by drying out the mouth and restricting blood flow to the gums, and they are detrimental to heart health as well. Seeking support to quit can yield substantial benefits.
Finally, communication with your healthcare team is essential. Patients should feel comfortable discussing blood pressure with their dentist and oral health with their doctor. Sharing medical history, discussing medication side effects, and asking for personalized recommendations can lead to better overall health outcomes. To learn more, visit Heart.org/OralHealth.
This initiative matters because it bridges a longstanding gap between dental and medical care. By integrating oral health into overall health management, healthcare providers can detect risks earlier and intervene more effectively, potentially saving lives. As research continues to uncover the links between oral bacteria and systemic diseases, the role of dentists as key members of the healthcare team is becoming increasingly clear. For patients, the message is simple: taking care of your teeth and gums is also taking care of your heart.
