The Claim
Aortic valves from patients with severe valve disease contain bacterial species commonly found in the oral cavity, including periodontal pathogens from Socransky’s red and orange complexes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Bacteria from the mouth, including those linked to gum disease, are found in the heart valves of people with severe valve disease.
See the scientific wording
The bacterial composition of aortic valves in patients with severe valve disease includes species commonly found in the oral cavity, including periodontal pathogens from Socransky’s red and orange complexes, suggesting oral microbiota may contribute to valve colonization.
Bacteria from infected gums enter the bloodstream through damaged tissue, travel to the heart, and stick to damaged heart valves where they grow and trigger inflammation that worsens valve damage.
What the research says
1 studyStudy: Oral Dysbiosis Is Associated with the Pathogenesis of Aortic Valve Diseases
Scientists found the same types of mouth bacteria, especially those linked to gum disease, inside the diseased heart valves of patients — suggesting these bacteria traveled from the mouth to the heart.
