Oral health has long been associated with a beautiful smile and outward appearance, but recent medical research reveals a deeper and more alarming truth: oral health is closely linked to the well-being of the heart and blood vessels.
When oral hygiene is neglected, bacteria begin to accumulate on the teeth and gums, causing chronic inflammation that can spread into the bloodstream. Bacteria such as Streptococcus mutans and Porphyromonas gingivalis are far from harmless; they can activate platelets and form small clots. Over time, this process accelerates atherosclerosis and increases the risk of developing cardiovascular disease.
Studies have shown that people with gum disease are more likely to suffer from high blood pressure, cardiac rhythm disorders such as atrial fibrillation or atrial tachycardia, and coronary artery disease. Oral bacteria alone can directly contribute to arterial narrowing and blockage, which is one of the most dangerous factors leading to heart attacks—a major life-threatening condition.
The problem does not stop there. Patients with uncontrolled diabetes often face more severe gum infections. Recent research indicates that treating gum disease not only improves oral health but also helps lower HbA1c levels, even when lifestyle factors such as smoking and diet are managed. Moreover, patients with periodontal disease often present with higher cholesterol and triglyceride levels, further increasing the risk of arterial blockage.
This highlights the vital importance of daily oral care—not only for preserving teeth, but also for protecting the heart. Brushing two or three times a day, using dental floss or a water flosser, and visiting the dentist regularly are simple steps proven to reduce the risk of heart disease by up to 14%, according to several studies.
