Periodontal Disease, Heart Disease and Stroke
Periodontal disease, heart disease and stroke may seem to be unlikely bedfellows, but researchers have found that gum disease sufferers are nearly twice as likely to also suffer from coronary heart disease. In addition, research studies have discovered that oral infection is indeed a risk factor for stroke. People diagnosed with acute cerebrovascular ischemia were more likely to also be experiencing some degree of periodontal disease.
Periodontal disease is a progressive condition in which the gingival tissue surrounding the teeth is infected by the colonization of bacteria. Bacteria found in plaque colonize first above, then below the gumline, causing the tissue to pull away from the teeth. If periodontal disease is left untreated, deep pockets form between the gums and the teeth and the tissue of the underlying jawbone is also destroyed. The destruction of bone tissue causes the teeth to shift, wobble or completely detach from the bone.
Coronary heart disease occurs when the walls of the coronary arteries become progressively thicker due to the buildup of fatty proteins. The heart then suffers from a lack of oxygen and must labor significantly harder to pump blood to the rest of the body. Coronary heart disease sufferers sometimes experience blood clots which obstruct normal blood flow and reduce the amount of vital nutrients and oxygen the heart needs to function properly. This phenomenon often leads to heart attacks.
Reasons for the Connection
There is little doubt that the presence of periodontal disease can exacerbate existing heart conditions. The periodontist and cardiologist generally work as a team in order to treat individuals experiencing both conditions.
There are several theories which may explain the link between heart disease, stroke and periodontal disease, which include the following:
-
Oral bacteria affect the heart – There are many different strains of periodontal bacteria. Researchers assert that some of these strains of bacteria enter the bloodstream and attach to the fatty plaques in the heart blood vessels (coronary arteries). This attachment then contributes to clot formation causing grave danger to the individual.
-
Inflammation – Periodontal disease causes severe inflammation in the gum tissue which elevates the white blood cell count and also the high sensitivity C-reactive protein levels. Research studies have shown that elevated levels of C-reactive proteins have been linked to heart disease.
-
Infectious susceptibility – Individuals who experience particularly high levels of oral bacteria may have weaker immune systems and an inadequate host inflammatory response. These factors may induce specific vascular effects which have previously been shown to contribute in the onset of certain forms of heart disease.
Diagnosis and Treatment
Since periodontal disease appears to be a risk factor for both heart attack and stroke, it is extremely important to seek immediate treatment. Initially, the periodontist will conduct thorough examinations to assess the exact condition of the teeth, gums and jawbone. X-rays can be helpful in determining whether bone loss is prevalent in the upper and lower jaw.
The dentist is able to conduct deep cleaning treatments such as scaling and root planing to remove hardened calculus (tartar) deposits from the gum pockets. An antibiotic may be prescribed to ensure that the bacterium is completely destroyed and the periodontal infection does not spread. In most cases, periodontal disease can be prevented with regular cleanings and proper home care.

Frequently Asked Questions
About
Periodontal Disease, Heart Disease and Stroke
Is there really a connection between gum disease and heart disease?
Yes. Research has consistently shown that people with periodontal (gum) disease are nearly twice as likely to suffer from coronary heart disease compared to those with healthy gums. Studies have also identified gum disease as a risk factor for stroke. While gum disease may not directly cause heart problems, the two conditions share underlying processes — chronic inflammation and bacterial activity — that significantly affect cardiovascular health.
How can a problem in my mouth affect my heart?
Researchers have identified several possible explanations. Harmful oral bacteria can enter the bloodstream through inflamed gum tissue and attach to fatty plaques inside the arteries, contributing to clot formation. Chronic gum inflammation also raises levels of C-reactive protein and white blood cells, both of which are linked to heart disease. In short, your mouth is a gateway to your bloodstream, and what happens there can affect your entire cardiovascular system.
What is periodontal disease?
Periodontal disease, also called gum disease, is a progressive bacterial infection of the tissues surrounding your teeth. It begins when plaque bacteria accumulate above and below the gumline, causing inflammation and gum recession. If left untreated, deep pockets form between the gums and teeth, the supporting jawbone is destroyed, and teeth may eventually loosen or fall out.
Does gum disease cause heart attacks or strokes?
Gum disease is not a direct cause of heart attacks or strokes, but it is a recognized risk factor. The chronic inflammation and bacteria associated with periodontal disease can worsen existing cardiovascular conditions and may contribute to the development of new ones. Treating gum disease is one of several important steps in protecting your cardiovascular health.
What role does inflammation play in this connection?
Inflammation is the common thread. Periodontal disease causes ongoing inflammation in your gums, which raises levels of C-reactive protein in the blood — a marker doctors associate with increased risk of heart attack and stroke. Reducing oral inflammation through proper dental care may also help reduce systemic inflammation throughout your body.
Can treating gum disease reduce my risk of heart problems?
Although treating gum disease alone won’t prevent heart disease, controlling oral infection and inflammation is an important part of a healthy overall approach. Patients who manage periodontal disease often see reduced inflammation markers in the body. We always recommend working with both your dentist and your physician for the best long-term outcome.
Who is most at risk?
People at higher risk for the combined effects of gum disease and cardiovascular problems include smokers, individuals with diabetes, people with poor oral hygiene, those with a family history of heart disease, and patients who already have high blood pressure, high cholesterol, or other cardiovascular conditions. If any of these apply to you, regular dental visits become even more important.
What are the warning signs of gum disease?
Common signs include red, swollen, or tender gums; bleeding when brushing or flossing; persistent bad breath; gum recession or longer-looking teeth; loose teeth; and pus along the gumline. Many people have early gum disease without obvious symptoms, which is why routine dental exams are essential — we can detect problems before you can.
How is gum disease diagnosed?
We perform a comprehensive periodontal evaluation, which includes measuring the depth of the pockets around each tooth, examining the gums for inflammation, checking for bone loss using digital X-rays, and assessing overall plaque and tartar levels. This gives us a complete picture of the health of your gums and jawbone.
How is gum disease treated?
Treatment depends on severity. Mild cases can often be reversed with improved home care and a professional cleaning. Moderate to advanced cases typically require scaling and root planing — a deep cleaning that removes hardened tartar from beneath the gumline — and sometimes antibiotic therapy. In advanced cases, periodontal surgery or laser treatment may be needed.
If I have a heart condition, should I tell my dentist?
Absolutely. Always inform our team about any heart conditions, recent cardiovascular procedures, medications you’re taking (especially blood thinners), or whether you have artificial heart valves or stents. This information helps us deliver safer, more personalized care and coordinate with your cardiologist when needed.
Should my cardiologist and dentist work together?
Yes, especially if you have an established heart condition along with periodontal disease. Your periodontist and cardiologist may collaborate to ensure that your dental treatment is safe and that your oral health supports your cardiovascular care. Open communication between both providers leads to better outcomes.
How can I prevent gum disease and protect my heart?
The best protection is consistent prevention. Brush twice a day, floss daily, eat a balanced diet, avoid tobacco, manage blood sugar if you have diabetes, control blood pressure and cholesterol, and visit us every six months for professional cleanings and exams. Healthy gums and a healthy heart go hand in hand.
When should I see a dentist about my gums?
Schedule an appointment right away if you notice bleeding gums, persistent bad breath, gum recession, loose teeth, or any pain or swelling around the gums. Even without symptoms, regular six-month checkups are essential — early treatment is much easier, more effective, and far less expensive than treating advanced gum disease.
