New research suggests that bacteria responsible for gum disease may contribute to the development of calcific aortic valve stenosis (CAVS), a serious condition that narrows the heart’s aortic valve. Researchers found that the bacterium Porphyromonas gingivalis may trigger inflammation and calcium buildup in the heart valve, potentially accelerating disease progression. In laboratory and animal studies, reducing inflammation or preventing bacterial infection lowered valve damage. Although the findings are preliminary and have not yet been confirmed in humans, they highlight a possible connection between oral health and heart disease. Researchers say maintaining good oral hygiene may play an important role in supporting long-term cardiovascular health while further clinical studies are underway.
