Presence of periodontal pathogenic bacteria in blood of patients with coronary artery disease

Cross-Sectional Study

Scientists found oral bacteria linked to gum disease in the blood of people with severe artery calcification — and even in healthy people — meaning these bacteria can travel from the mouth to the bloodstream, just like the claim says.

Bacteria that cause gum disease are often found in the fatty buildups in your arteries—this suggests that poor oral health might be linked to heart disease, even though it doesn’t prove one causes the other.
