For years, patients have heard that gum disease and heart disease might be connected, and the research on this topic has only grown since. According to a scientific statement from the American Heart Association, there is a real, measurable association between periodontal disease and atherosclerotic cardiovascular disease, though researchers have not established that one directly causes the other.
What Researchers Have Found
Multiple large studies have found that people with periodontal disease, the more advanced form of gum disease that affects the bone and tissue supporting the teeth, tend to have higher rates of cardiovascular events like heart attack, stroke, atrial fibrillation, and heart failure. The American Heart Association’s 2025 statement notes that this association appears to hold even when accounting for shared risk factors like smoking and diabetes, suggesting the two conditions may be connected independently of those overlapping risks.
Association Is Not the Same as Causation
It’s important to be precise about what the research does and doesn’t show. Periodontal disease involves chronic inflammation, and that inflammation is also a known contributor to cardiovascular disease. This shared inflammatory pathway is one reason researchers suspect a connection. However, the American Heart Association has been clear that a direct cause-and-effect relationship has not been confirmed, and there is currently no strong evidence that treating gum disease on its own will prevent heart disease. Well-designed long-term studies are still needed to answer that question conclusively.
What This Means for Your Dental Care
None of this changes the basic advice: healthy gums are worth protecting for their own sake, and a possible connection to heart health is one more reason not to ignore symptoms like bleeding, swelling, or persistent bad breath. If you notice any of these warning signs that it’s time to see the dentist, don’t wait for your next scheduled cleaning.
Maintaining good oral hygiene, including consistent brushing and flossing, along with regular professional cleanings, remains the most reliable way to prevent and manage gum disease regardless of what future research reveals about its relationship to cardiovascular health.

Frequently Asked Questions About Gum Disease and Heart Health
Does treating gum disease prevent heart disease?
There currently isn’t strong evidence that treating gum disease on its own prevents heart disease. Researchers have found an association between the two conditions, but a direct cause-and-effect relationship hasn’t been established.
Why do researchers think gum disease and heart disease might be connected?
Both conditions involve chronic inflammation, and studies show the association between them holds even after accounting for shared risk factors like smoking and diabetes, which suggests an independent connection worth continued study.
Should I tell my dentist if I have heart disease?
Yes. Sharing your full medical history, including any cardiovascular conditions, helps your dental team provide more informed care and watch for relevant symptoms.
What are the warning signs of gum disease?
Bleeding or swollen gums, persistent bad breath, and gums that appear to be receding are common early signs and are worth mentioning to your dentist rather than waiting for your next scheduled visit.
Is this research settled, or is it still being studied?
It’s still being actively studied. The American Heart Association has called for more long-term studies and clinical trials to determine whether periodontal treatment can influence cardiovascular outcomes.
