Dentists and doctors have traditionally been viewed as separate healthcare providers, but a growing body of evidence reveals that oral health and cardiovascular health are deeply interconnected. The American Heart Association (AHA), in collaboration with Delta Dental of California, is addressing this link through its Healthy Smiles, Healthy Hearts initiative, which encourages dental teams to adopt a total-body perspective when treating patients.
At the core of this connection is inflammation. When gums become inflamed due to periodontal disease, bacteria from the mouth can enter the bloodstream. This can contribute to blood vessels constricting or becoming blocked, forcing the heart to work harder and potentially raising blood pressure. Such mechanisms increase the risk of heart disease and stroke. The prevalence of these conditions is staggering: more than 46% of U.S. adults have high blood pressure, and over 40% of adults aged 30 and older are affected by periodontal disease.
To combat these intertwined health threats, the initiative promotes simple but impactful steps, such as conducting blood pressure screenings during routine dental checkups. These screenings can provide a more complete picture of a patient's overall health and help identify risks early. As Daniel Croley, D.M.D., chief dental officer at Delta Dental of California and Affiliates, explained, “The mouth is a gateway to the body and can often reveal more about your total body health than you may think. 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, the AHA offers four practical tips to protect both teeth and heart. First, maintain a consistent oral hygiene routine: brush at least twice daily with fluoride toothpaste and floss once a day to disrupt plaque-forming bacteria. Brushing gently is crucial to avoid enamel wear and gum recession. Second, eat a heart-healthy diet that limits sugar and refined carbohydrates, since sugar feeds harmful oral bacteria that produce acid and lead to cavities and gum disease. Prioritize vegetables, lean proteins, complex carbohydrates, and healthy fats. Third, avoid all tobacco products, including vaping and chewing tobacco, which dry out the mouth, restrict blood flow to gums, and elevate risks of periodontal disease, tooth loss, and oral cancer. Finally, communicate openly with your healthcare team. Discuss blood pressure with your dentist and oral health with your physician, and share your medical history and medication side effects to receive personalized recommendations.
This integrative approach matters because it shifts the focus from isolated treatment to prevention and early detection. By bridging the gap between dentistry and medicine, the Healthy Smiles, Healthy Hearts initiative aims to reduce the burden of both cardiovascular disease and oral disease, ultimately saving lives.
