Preliminary Research Links Gum Disease Bacteria to Heart Valve Damage

New preliminary research presented at the American Heart Association's Basic Cardiovascular Sciences Scientific Sessions 2026 suggests that bacteria associated with gum disease may contribute to the development of calcific aortic valve stenosis. Researchers found that these bacteria could trigger inflammation and calcium buildup in the heart valve, indicating that maintaining good oral health might play a role in reducing the risk of this serious heart condition.
