Gum Bacteria May Inflame, Harden Heart Valves
New research presented at the American Heart Association suggests that bacteria associated with gum disease may contribute to the calcification of heart valves. This finding could lead to new preventive treatments for calcific aortic valve stenosis.

BOSTON, July 12, 2026 - Gum disease bacteria may spur calcium buildup in the heart's aortic valve , leading to a common and serious heart valve disease, according to preliminary, independent research presented at the American Heart Association's Basic Cardiovascular Sciences Scientific Sessions 2026 . The meeting, in Boston, July 13-16, 2026, is one of the largest meetings globally dedicated to fundamental and translational research in cardiovascular science.
According to the American Heart Association, calcific aortic valve stenosis (CAVS) occurs when the aortic valve thickens and calcifies, restricting blood flow from the heart to the rest of the body. In early stages, there may be no symptoms; however, as the condition progresses, it can cause fatigue, chest pain, shortness of breath, fainting, heart failure and sometimes premature death. Standard treatment for severe CAVS is valve replacement surgery .
