DALLAS, Dec. 16, 2025 — There is increasing evidence that gum disease is associated with increased risk of cardiovascular events, including heart attack, stroke, atrial fibrillation, heart failure and cardiometabolic health conditions. Effective…
A scientific statement from the American Heart Association indicates that gum disease, known as periodontitis, is independently associated with an increased risk of atherosclerotic cardiovascular disease. This means people with gum disease have a higher likelihood of developing conditions such as heart attack, stroke, and peripheral artery disease.
The connection is thought to involve inflammation. Inflammation caused by gum disease can lead to systemic inflammation throughout the body, which may affect blood vessels and contribute to plaque buildup in arteries. Bacteria from the mouth can also enter the bloodstream. Gum disease may also worsen existing cardiovascular risk factors, including high blood pressure and type 2 diabetes. Both gum disease and heart disease share common risk factors such as smoking, age, and diabetes.
While a significant association exists, there is no definitive evidence yet that treating gum disease directly prevents cardiovascular events. However, maintaining good oral hygiene is beneficial for overall health.
The statement recommends that individuals with gum disease be informed of their increased cardiovascular risk. Conversely, people with atherosclerotic cardiovascular disease should be screened for gum disease. Dental professionals are advised to ask patients about a history of heart disease and refer them to a physician if needed. Physicians should also inquire about symptoms of gum disease and suggest dental evaluations. Emphasized practices include regular brushing, flossing, professional dental checkups, quitting smoking, and controlling blood sugar levels, all of which benefit both oral and cardiovascular health.
