People with chronic gum disease have a higher risk of cardiovascular problems, including heart attacks and stroke.

Researchers have spent years examining the relationship between gum disease and heart disease, and the picture that has emerged is consistent. The link is statistical and biologically plausible, driven by systemic inflammation that travels from inflamed gum tissue into the bloodstream.

This guide explains what the link is, how it works at a biological level, what UK research from the British Heart Foundation and the University of Aberdeen has shown, and what you can do to protect both your gums and your heart.

Is There a Link Between Gum Disease & Heart Disease?

Yes. Multiple studies over the past two decades have shown that people with gum disease are more likely to develop cardiovascular problems than people with healthy gums. The British Heart Foundation, the British Society of Periodontology, and major academic research centres all recognise the connection between gum disease and heart disease.

What the evidence does NOT yet show conclusively is direct causation. The link is statistical and biologically plausible, but proving that gum disease itself triggers heart disease, rather than the two conditions sharing common risk factors such as smoking, diabetes, and poor diet, remains an active area of research. The British Heart Foundation summary is the most accessible UK source for current evidence.

The practical takeaway: even if causation is not fully proven, the association is strong enough that leading health bodies advise taking gum disease seriously as part of overall cardiovascular health management.

How Gum Disease Affects the Heart

The most widely accepted explanation centres on inflammation.

When you have gum disease, the bacteria living in the inflamed gum tissue do not stay in your mouth. They enter the bloodstream every time you brush, floss, eat, or have dental work done. Once in circulation, these bacteria and the inflammatory chemicals your body produces in response travel throughout the body, including to the heart and blood vessels.

This systemic inflammation does several things:

• Activates the liver to produce C-reactive protein (CRP), a marker of inflammation that is also a known risk factor for cardiovascular disease
• Triggers white blood cells to release inflammatory chemicals that damage the inner lining of blood vessels
• Contributes to atherosclerosis, the build-up of fatty plaques on artery walls that narrows blood vessels and can lead to heart attacks and strokes
• In rare cases, causes endocarditis, an infection of the heart’s inner lining, when oral bacteria settle on damaged heart valves

In short, gum disease is not a problem isolated to the mouth. It is a chronic inflammatory condition with effects that reach the cardiovascular system.

Can Gum Disease Cause Heart Palpitations?

Heart palpitations are a less commonly discussed symptom in the context of gum disease, but there is a plausible connection through systemic inflammation.

Palpitations (the sensation of your heart racing, fluttering, or skipping a beat) can be triggered by a range of factors, including stress, caffeine, hormonal changes, and inflammation. Because chronic gum disease drives systemic inflammation and can put additional strain on the cardiovascular system, it is one of many possible contributing factors in patients who experience unexplained palpitations.

That does not mean every case of palpitations is caused by gum disease. Palpitations have many causes, and most are not serious. However, if you have unexplained heart palpitations alongside symptoms of gum disease such as bleeding gums or recession, raise both with your GP and your dentist. Treating the gum disease may help reduce the inflammatory load on your heart and ease the palpitations indirectly.

Expert Tip: Heart palpitations should always be assessed by a GP or cardiologist in the first instance. Gum disease may contribute, but it is not usually the primary cause and a proper cardiac assessment is essential.

What the UK Research Says

The University of Aberdeen, with funding from the British Heart Foundation, ran a study looking at 160 patients admitted to Aberdeen Royal Infirmary with a heart attack. About two-thirds of those patients had a severe gum infection. Patients with higher levels of Porphyromonas gingivalis (the main bacterium driving gum disease) in their mouths tended to have more damage to their hearts. The University of Aberdeen news summary covers the study in detail.

Other UK research, summarised by the British Society of Periodontology, has shown:

• People with chronic periodontitis have an increased risk of cardiovascular events
• The inflammatory markers found in active gum disease overlap with those found in cardiovascular disease
• Treating gum disease appears to reduce some cardiovascular risk markers, though the effect on actual heart attack rates is still being studied

The collective picture is consistent: gum health and heart health are connected, and looking after one supports the other. The full BSP summary is worth reading if you want the longer view.

Expert Tip: Ask your GP whether your most recent blood tests included C-reactive protein. If CRP is elevated and you also have gum disease symptoms, treating the gum disease is one of the most cost-effective ways to reduce that systemic inflammation marker.

How to Reduce Your Risk

The good news is that the same measures that protect against gum disease also support cardiovascular health. Both conditions respond to similar lifestyle and oral hygiene measures, so improvements compound across both fronts.

• Brush twice a day with a fluoride toothpaste
• Clean between your teeth daily with floss or interdental brushes
• Attend regular hygiene appointments, typically every 3 to 6 months
• Stop smoking, the single biggest dual risk factor
• Manage blood sugar if you have diabetes
• Eat a balanced diet with adequate vitamin C
• Address bleeding gums quickly rather than waiting for them to progress

If you have already been diagnosed with gum disease, follow your treatment plan and attend your reassessment appointments. Stabilising your gum health is a meaningful part of overall cardiovascular protection, and most patients see inflammatory markers improve within a few months of starting therapy. Bringing the gum disease under control reduces one variable from the broader risk picture.

For patients with cardiovascular risk factors, an early periodontal assessment is one of the simplest, most evidence-based steps you can take to protect long-term heart health alongside your dental health.

Gum Disease & Heart Health: What to Remember

The link between gum disease and heart disease is one of the clearest examples of how oral health affects the rest of the body. Patients with chronic gum disease consistently show higher rates of cardiovascular problems, and the biological mechanism through systemic inflammation is well understood even if direct causation is not yet conclusively proven. The actions you take to protect your gums also protect your heart, and the cost of addressing gum disease is far less than the cost of cardiovascular complications later in life.

The five things to take from this guide:

• Statistical link via inflammation: gum disease and heart disease are statistically linked through systemic inflammation
• Key bacterium: Porphyromonas gingivalis is the bacterium most strongly implicated in both
• UK evidence: BHF-funded research at the University of Aberdeen supports the connection
• Palpitations: inflammation can contribute, but always need cardiac assessment first
• Low-cost intervention: treating gum disease is a high-evidence step toward cardiovascular protection

If you have noticed bleeding gums, recession, or any other gum disease symptoms, and you also have cardiovascular risk factors, a periodontal assessment is one of the most useful next steps you can take to protect both your dental and your overall health.
