Early research links a gum disease bacterium to heart valve calcification
Preliminary research at an American Heart Association meeting examined valve tissue from valve-replacement patients and found the gum disease bacterium Porphyromonas gingivalis among the biggest differences in calcified aortic valves; in mice, repeated exposure caused valve calcification. It is not yet peer-reviewed and shows an association, not proof of cause; a human study is under way.
What it means for you
Evidence linking gum health and general health keeps growing; looking after your gums and treating gum disease early may benefit overall health.
Editors' take: the background
Porphyromonas gingivalis is a bacterium closely tied to gum disease. When gums are inflamed, bacteria can enter the bloodstream through them, which is why researchers study links between gum disease and heart health.
An association is not proof of cause: people with gum disease may share other risk factors, such as smoking. Human studies are needed to show whether treating gum disease lowers heart risk.
Key points
- Preliminary: association, not proven cause
- See a dentist early for bleeding or swollen gums
- Brush and clean between teeth daily; regular check-ups

Questions readers ask
I have a heart condition. What should I tell my dentist?
Tell them your medical history and current medicines, such as blood thinners. Some patients need their cardiologist's input before certain dental treatment.
How do I know if I have gum disease?
Bleeding when brushing, red or swollen gums, lasting bad breath and loose teeth are common signs. A dentist can confirm it by measuring gum pockets and taking X-rays.
