Bleeding gums may seem like a minor dental problem, but they can be an early warning that inflammation and infection are developing around the teeth. When gum disease is ignored, its effects can extend beyond the mouth and may be associated with conditions affecting the heart and blood vessels.

Heart Awareness Month is a useful reminder that caring for your heart involves more than watching what you eat and checking your blood pressure. Research has found that people with severe gum disease, known as periodontitis, are more likely to experience cardiovascular problems, including heart disease and stroke.

What Is Gum Disease?

Gum disease begins when plaque, a sticky layer of bacteria, builds up along the gumline. If it is not removed by brushing and cleaning between the teeth, plaque can harden into tartar. Only a dental professional can remove tartar.

The earliest stage of gum disease is gingivitis. Signs include red, swollen, or tender gums that bleed when you brush or floss. At this stage, gum disease can often be reversed with good daily oral hygiene and professional dental care.

If left untreated, gingivitis can develop into periodontitis. The gums pull away from the teeth, creating pockets where bacteria can grow. Over time, the infection can damage the gums and bone that hold the teeth in place. This may cause receding gums, loose teeth, and eventually, tooth loss.

How Are the Gums and Heart Connected?

Researchers are still studying the connection. Gum disease is linked to a higher risk of heart and blood vessel problems, but there is no proof that it directly causes heart disease.

Inflammation may be one link. Periodontitis causes long-term gum inflammation, which may add to inflammation elsewhere in the body and contribute to atherosclerosis. This is a build-up of fatty deposits inside the arteries that can restrict blood flow and increase the risk of a heart attack or stroke.

Bacteria may also play a role. When gums are inflamed or bleeding, bacteria from the mouth can enter the bloodstream during brushing, flossing, or chewing. Oral bacteria have been found in fatty deposits inside arteries, although researchers do not yet fully understand their role.

In rare cases, bacteria in the bloodstream can cause infective endocarditis, a serious infection of the heart’s inner lining or valves. People with artificial heart valves, certain heart defects, or a history of endocarditis should always tell their dentist about their condition.

Shared Risk Factors Matter

The relationship is complicated because gum disease and heart disease share several risk factors. These include smoking, diabetes, an unhealthy diet, excess weight, and increasing age.

Diabetes deserves particular attention. High blood sugar can make gum infections more likely and harder to control. At the same time, severe gum inflammation may make it more difficult to manage blood sugar. People living with diabetes should therefore make dental care part of their regular health routine.

Smoking can also hide an important warning sign. It reduces blood flow to the gums, which means a smoker may have severe gum disease without obvious bleeding. Gums that do not bleed are not necessarily healthy.

Signs You Should Not Ignore

Arrange a dental examination if you notice:

• Gums that bleed regularly.
• Red, swollen, or painful gums.
• Bad breath that does not go away.
• A persistent bad taste in your mouth.
• Gums pulling away from your teeth.
• Pain when chewing.
• Pus between a tooth and the gum.
• Loose or shifting teeth.
• Changes in how your teeth meet when you bite.

Gum disease can progress without causing much pain, which is why regular dental examinations are important even when your mouth feels healthy.

Protecting Your Gums and Your Heart

Brush twice a day with fluoride toothpaste, and clean between your teeth daily using floss or a suitable interdental cleaner. Avoid smoking, manage diabetes and blood pressure, limit sugary foods and drinks, and attend regular dental check-ups.

Treating gum disease protects your teeth and gums and may reduce inflammation. However, it should never replace prescribed heart medication or medical care. Good oral health is one important part of protecting your heart.
