In plain English

Bacteria from inadequate dental hygiene are present in calcified heart valves and coronary arteries.

See the scientific wording

Oral pathogens from poor dental hygiene contribute to calcification of heart valves and coronary arteries.

Why this might work

Bacteria from unhealthy gums enter the bloodstream, stick to damaged heart valves, and activate immune cells that force valve cells to turn into bone-like cells, causing the valves to harden with calcium.

What the research says

2 studies

  1. Study: Infectious seeds of valve calcification: Exploring the bacterial hypothesis in the pathogenesis of calcific aortic valve disease

    Scientists found traces of mouth bacteria in some hardened heart valves and noticed that these valves also showed signs of turning into bone-like tissue, suggesting the bacteria might be helping the hardening process.

  2. Study: Oral Dysbiosis Is Associated with the Pathogenesis of Aortic Valve Diseases

    Scientists found bacteria from people's mouths in their heart valves, and those bacteria matched the bad bugs from their gums. This means poor dental hygiene might let mouth germs travel to the heart and cause damage.
