Good oral health does more than keep your teeth sparkling – it can help protect your heart. Cardiovascular disease (heart attacks and strokes) is the world’s number one killer, claiming roughly 17 million lives each year. Recent research shows a clear oral-systemic connection: people with gum disease are 2–3 times more likely to suffer a heart attack, stroke or other major heart problem. In fact, nearly half of adults have some form of periodontal (gum) disease. That means many of us – perhaps including your family and friends here in Wellington – have an under-the-radar risk factor for heart issues.
Regular care from your Wellington dental hygienist at Wholesome Smiles helps break this cycle. By keeping your gums healthy and plaque-free, we reduce the inflammation and bacteria that can harm your heart. Below we’ll explain how oral health affects cardiovascular health, why certain patients may need antibiotic coverage before dental work, and what you can do to protect both your smile and your heart. Our goal is friendly, easy-to-understand advice so you feel empowered – because your heart deserves a smile, too.
The Mouth-Heart Connection
Inflamed gums and infected teeth aren’t just local problems – they put stress on your whole body. Gum disease is an infection that causes chronic inflammation. Over time this inflammation floods your blood with harmful signals that can injure blood vessels and the heart. The bacteria in your mouth can even enter the bloodstream. Doctors have detected oral bacteria like Porphyromonas gingivalis inside arterial plaques in heart patients.
Every time you chew, brush or get dental work, bacteria in inflamed gums can slip into your circulation. Once there, they trigger an immune response and inflammation in your arteries. Over the years this can accelerate atherosclerosis (hardening of arteries), raising the risk of heart attack or stroke. It’s a bit like your mouth being a gateway for trouble – which is why good hygiene matters.
Statistically, the link is striking: studies show those with moderate or severe gum disease have around 30–60% higher risk of heart disease compared to people with healthy gums. And since about 47% of adults have some gum disease, it’s a common risk factor. The good news? By treating gum disease and practising healthy habits, you reduce that risk.
Key Oral Bacteria: S. mutans and P. gingivalis
Two usual suspects tie oral infections to heart trouble:
Streptococcus mutans. This bacterium causes tooth decay (cavities), but it doesn’t just stop at your teeth. S. mutans can enter the bloodstream through tiny wounds in your mouth. It has been recovered from heart valve infections (endocarditis) in some studies. Left unchecked, it can contribute to inflammation on heart tissues.
Porphyromonas gingivalis. This is the major gum disease bug. P. gingivalis thrives in deep gum pockets and causes chronic periodontitis. Research has repeatedly found P. gingivalis inside arterial plaques in heart patients. Animal experiments show that introducing P. gingivalis into the blood can accelerate artery inflammation and plaque buildup. In plain terms, this mouth germ can “hitch a ride” to your heart and incite damage.
By controlling these bacteria in your mouth, you lower the chance they’ll affect your vessels. That’s why your Wellington dental hygienist scrubs away plaque and tartar – to starve these germs of the sticky biofilm where they live.
Antibiotic Prophylaxis: Who Needs a Pre-Med
If you have certain heart conditions, your dentist or hygienist may recommend taking antibiotics before some dental procedures. This is called “prophylaxis”, and it prevents bacteria from causing an infection in the heart (infective endocarditis). Today’s guidelines limit prophylaxis to a few high-risk groups. You might need it if you have:
Prosthetic (artificial) heart valves or any prosthetic material used for heart valve repair.
A history of infective endocarditis (a prior serious heart infection).
Certain congenital heart defects (for example, unrepaired cyanotic heart disease or repaired defects with prosthetic material in the last 6 months).
A heart transplant recipient who developed valve problems.
If you fall into one of these categories, even a routine cleaning or filling could allow germs into your blood. In those cases, Wholesome Smiles’ dental hygienists will coordinate with your doctor to give you a dose of antibiotics beforehand. This tiny extra step can be life-saving for patients at risk.
For most patients without these conditions, prophylaxis is not needed. (Joint replacements used to be a concern in the past, but guidelines say antibiotics are generally not needed for those with hip or knee joints.) The key is open communication: always tell your hygienist if you have a congenital heart issue, prior endocarditis, valve surgery, or a transplant.
Who’s at Greater Risk? (Don’t Ignore These Signs)
Certain people need to be extra vigilant about gum and heart health:
People with diabetes. High blood sugar weakens the immune system and feeds bacteria. Diabetes roughly doubles or triples the risk of gum infections. The inflamed gums in turn make blood sugar harder to control.
Smokers and tobacco users. Smoking not only raises heart risk by itself; it also cuts blood flow to your gums. Smokers are much more likely to get severe periodontitis.
Older adults. As we age, we naturally have more wear on our teeth and gums. Many older people have some gum recession or chronic gum problems. Age itself is also a heart risk factor.
People with cardiovascular or immune conditions. If you already have heart disease, high blood pressure, high cholesterol, or immune-suppressing conditions, you’re more vulnerable.
Pregnant women. Hormonal changes during pregnancy can cause “pregnancy gingivitis”, where gums become swollen and bleed easily.
Anyone noticing red, swollen, or bleeding gums, persistent bad breath, or loose teeth should consult their Wellington dental hygienist promptly. These are early warning signs of gum disease.
Practical Tips: Keep Your Mouth (and Heart) Healthy
Taking care of your teeth and gums is simple and pays off in both a brighter smile and a healthier heart:
Brush twice a day for 2 minutes. Use fluoride toothpaste and a soft-bristled brush. Angle the brush along the gum line to remove plaque. Floss daily too – it cleans between teeth where a brush can’t reach.
Use antiseptic rinse or interdental cleaners if recommended.
Eat a heart-healthy diet. Focus on fruits, vegetables, whole grains, and lean protein. Limit sugary snacks and drinks.
Quit tobacco and limit alcohol. Smoking and heavy drinking increase inflammation and heart disease risk.
Stay hydrated. Water helps wash away food particles and supports saliva production.
Manage stress and stay active. Chronic stress hurts both your mouth and heart. Regular exercise boosts circulation and immune function.
Never ignore oral problems. Treating dental issues early keeps bacteria from spreading into your bloodstream.
Healthy habits protect your mouth – and by extension, your cardiovascular system.
