Gum Disease and Cardiovascular Disease: What’s the Connection?
Gum disease (periodontal disease) is a chronic infection and inflammation of the tissues that support your teeth. Cardiovascular disease often involves inflammation too—especially in atherosclerosis, where fatty plaques build up inside arteries. Because both conditions share inflammatory pathways (and many of the same risk factors), researchers have been studying how oral health and heart health may be related. (PubMed)
What the Research Suggests (and What It Doesn’t)
Many studies have found an association between periodontal disease and a higher likelihood of cardiovascular problems such as heart attack and stroke. In several large analyses, the increased risk is often reported in the range of ~20–50% higher in people with periodontitis compared to those without (though results vary by study design and population). (ScienceDirect)
Importantly, major organizations (including the American Heart Association) note that an association does not prove cause-and-effect. Periodontal disease may contribute to chronic inflammation, but research has not definitively shown that treating gum disease prevents heart attacks or strokes. (PubMed)
The Inflammation Connection
Inflammation is part of your body’s natural defense system. Short-term (acute) inflammation helps fight infection. But when inflammation becomes long-term (chronic)—as can happen with untreated periodontal disease—it may place ongoing stress on the body and is also involved in the development and progression of atherosclerosis. (PubMed)
A Noteworthy Animal Study
In an often-cited rabbit experiment (used to model aspects of human heart disease), rabbits fed a cholesterol-rich diet were exposed to periodontal-disease–related bacteria. Those rabbits developed less stable arterial plaques and had higher inflammatory markers than rabbits that were not exposed. Researchers also investigated an inflammation-resolving topical agent (Resolvin E1) that reduced gum inflammation and was linked with improvements in arterial inflammation in that model. (Harvard Health)
(Animal studies are valuable for understanding mechanisms, but they don’t always predict exactly what will happen in humans.)
What You Can Do Right Now
The good news: early gum disease (gingivitis) is often reversible with consistent home care and professional cleanings.
- Brush twice daily and clean between teeth daily (floss or interdental brushes)
- Keep up with regular dental checkups and cleanings
- If you’ve been told you have gingivitis, ask your dental team to show you personalized brushing/flossing techniques
- If gum disease has progressed to periodontitis, don’t ignore it—treating infection and inflammation helps protect your teeth and supporting bone, and supports overall wellness (PubMed)
When Gum Disease Progresses
When gingivitis worsens into periodontal disease, the gums can detach from the teeth and form deeper “pockets” where bacteria thrive. Over time, this can lead to bone loss, loose teeth, and ultimately tooth loss.
