Ask your dentist about gum health: the AHA update on heart links

Should people with heart risk factors talk to their dentist about gum disease—and does treating gum disease lower the risk of heart attack or stroke? A new American Heart Association (AHA) scientific statement (published online December 16, 2025) updates the evidence and explains where the link is stronger, and where it’s still uncertain.

The practical takeaway: even though the evidence does not prove that gum treatment prevents heart events, periodontal care can help you address a common, inflammatory oral condition. That’s a reasonable part of “whole-body” prevention—especially if you have gum bleeding, persistent bad breath, diabetes, or other heart risk factors.

What the AHA statement adds (and what it doesn’t)

According to the AHA statement, periodontal disease is associated with atherosclerotic cardiovascular disease (ASCVD) outcomes. The statement also discusses possible biological pathways (for example, chronic inflammation and proposed mechanisms involving bacteria related to gum pockets).

At the same time, the AHA emphasizes key limits:

Association is not the same as cause: the statement does not confirm that gum disease directly causes ASCVD events.
Treatment effect on heart events isn’t confirmed: the AHA notes that the evidence is not sufficient to conclude that periodontal treatment prevents heart attacks, strokes, or cardiovascular death.
More research is needed: the AHA calls for better long-term studies and randomized trials to clarify whether periodontal care changes cardiovascular outcomes.

So, an evidence-based way to frame it at your appointment is: “Gum disease is linked with cardiovascular risk, and periodontal treatment supports oral health. But it hasn’t been confirmed to prevent heart attacks or strokes.”

Why gum health still deserves a heart-health conversation

Gum disease starts with inflammation of the gums (gingivitis). If it progresses to periodontitis, it can involve damage to the tissues that support teeth and may be harder to fully reverse. The CDC notes that periodontal conditions are largely preventable and treatable, and that gum disease can often be managed with professional care and good at-home habits.

In the U.S., periodontal disease is common. For example, NIDCR reports that about 2 in 5 adults age 30 and older have some form of periodontal disease.

Also, periodontal disease and ASCVD share several risk factors (such as smoking and diabetes) and may be influenced by factors that affect access to healthcare. That means your dentist may help you identify and manage a modifiable health issue—without claiming it “solves” cardiovascular disease on its own.

What readers can do: a “dental visit script”

If you have known heart risk factors (or you’re simply trying to be proactive), here are practical questions you can bring to your next dental exam:

“Do I have signs of periodontitis?” Ask whether you should have periodontal screening and what the results mean.
“How would you describe my gum inflammation risk?” Request plain-language explanation (gingivitis vs. periodontitis, if applicable).
“What’s my care plan—and how will we measure progress?” For periodontitis, care often includes professional treatment plus a maintenance schedule.
“How do you think about my overall risk context?” Ask how your team views the AHA evidence—especially the difference between association and proven cardiovascular event prevention.
“Should I coordinate with my medical clinician?” If you have diabetes or take medications that affect oral health, ask whether sharing information between teams makes sense.

If you’re comfortable, bring a short list of medical diagnoses and current medications. (You’re not asking your dentist to manage cardiac care—just to support oral-health prevention as part of your overall wellbeing.)

Who may benefit from extra attention to gum health

While gum disease can affect anyone, NIDCR highlights differences in prevalence and risk across populations, and the CDC notes that gum disease can be present without obvious symptoms. If it’s been a while since your last dental visit—or if you smoke or have diabetes—it’s especially reasonable to ask for periodontal screening and a personalized prevention plan.

Uncertainty box: will periodontal treatment lower heart attack or stroke risk?

Here’s the most accurate bottom line from the AHA statement: the evidence has not been confirmed to show that treating periodontal disease prevents cardiovascular events. The link between gum disease and ASCVD outcomes is described as an association, but causality and the size of any potential “event prevention” effect remain uncertain.

What’s known with higher confidence is simpler: gum disease is common, and periodontal care is important for oral health. What’s still being studied is whether periodontal treatment changes ASCVD event rates beyond what would be expected from improved shared risk factors and reduced gum inflammation.

Bottom line

Ask your dentist about gum health if you have heart risk factors—or if you’re aiming for whole-person prevention. The AHA update supports that gum disease is associated with ASCVD, but it does not confirm that periodontal treatment directly prevents heart attacks or strokes. Still, periodontal screening and a solid prevention-and-maintenance plan are practical, evidence-based steps you can take as part of your overall health conversation.
