A cardiologist has highlighted an unexpected connection between oral health and heart disease. Dr Pradip Jamnadas explained on a podcast that poor dental hygiene and chronic sinus infections may significantly affect cardiovascular health. He stated that the microbiome extending from the nose and mouth to the digestive tract can predict cardiovascular disease risk. Bad teeth and bacteria in the mouth have been linked to valvular disease, aortic stenosis, premature calcification of the aortic valve, and coronary calcification. Chronic sinusitis, particularly fungal infections, can cause inflammation that leads to premature coronary artery disease. Studies show that bacteria from gum disease can enter the bloodstream through inflamed gums, contributing to arterial plaque formation and blood vessel inflammation. While not the sole cause, oral bacteria are considered an independent risk factor that can worsen heart conditions when combined with other risks like high cholesterol, diabetes, and smoking.
How Oral and Sinus Infections Affect Heart Health
Chronic or untreated sinus infections, whether bacterial or fungal, can lead to persistent low-grade inflammation throughout the body. This constant immune activation releases inflammatory markers such as C-reactive protein (CRP) and interleukins, which are also involved in atherosclerosis. Over time, this inflammatory state damages the lining of blood vessels, promoting plaque buildup and reducing vascular elasticity. Fungal sinus infections, though less common, can cause prolonged immune stress and may further burden the cardiovascular system, especially in people with weak immunity or pre-existing heart conditions. Maintaining good oral hygiene through brushing twice daily, flossing, and using antimicrobial mouthwash can reduce harmful bacteria. A balanced diet rich in fibre, probiotics, and antioxidants supports a healthy oral microbiome and indirectly supports cardiovascular wellness.
