Poor oral hygiene may lead to heart problems, experts warn

Our mouth often gives us early signs of other health problems in the body. Issues like mouth ulcers, bleeding gums, or bumps inside the mouth may point to deeper health conditions. If these are noticed early, they can be treated on time and may even help detect serious illnesses.

Experts say that poor oral hygiene leads to bacterial growth in the mouth. These bacteria can move into the bloodstream and reach the heart or other organs. This can cause dangerous health problems.

Dr. Shilpi Behl, a senior dentist and facial aesthetics expert, says that tooth infections, cavities, bleeding gums, and gum diseases like periodontitis are not just painful—they may be risky for the heart too. She adds that bone loss around teeth, dry mouth, and changes in how the tongue looks can also be signs of bigger health issues.

Gum disease linked to heart attack and stroke

New research has found that people with gum disease are 28% more likely to have a heart attack. Gum infections cause inflammation in the body. This inflammation can lead to heart problems like endocarditis, which is an infection of the heart lining.

There’s also a link between gum disease and heart palpitations—irregular heartbeats that can feel like pounding or fluttering. In some cases, these bacteria might increase the risk of stroke, especially in adults with long-term oral issues.

Children are not safe either. If they have serious tooth decay or infections in childhood, they may develop blocked arteries when they grow older. This can cause heart-related problems in adulthood.

Dr. Behl explains that it’s important to take care of oral hygiene every day. A few simple steps like brushing your teeth properly, flossing, and visiting the dentist regularly can help you avoid both dental and heart problems.

She says brushing at night is especially important because food remains in the mouth for a long time while we sleep. This can feed harmful bacteria. Also, flossing helps clean the parts between teeth where the brush can’t reach.

Easy ways to take care of your oral health

1. Brush twice daily – once in the morning and once at night.

2. Use floss – to remove food stuck between your teeth.

3. Visit your dentist – at least once every 3 months, even if you don’t have pain.

4. Eat a balanced diet – with foods rich in calcium and vitamin D. These keep your teeth strong.

5. Avoid too much sugar – as it causes cavities.

Dr. Behl also suggests using mouthwash if your dentist recommends it. It can help reduce bacteria in the mouth. Staying hydrated is also important, as dry mouth can lead to infections.

Many people ignore dental care until they feel pain. But by then, the problem might already be serious. Instead, regular care and early detection are the best ways to stay healthy—not just for your teeth, but for your heart and entire body.

So, next time you brush your teeth, remember—you’re not just keeping your smile clean, you’re also protecting your heart.
