Why do some people with clogged arteries have fewer mouth bacteria in their blood?

Scientists checked blood for bacteria from gum disease in people with and without severe artery calcification. They found less of certain gum bacteria in those with clogged arteries.

Bacteria from gum disease can escape from your mouth into your bloodstream and may help cause calcium buildup in your heart arteries and valves, which can lead to heart problems.
Bacteria from gum disease can sometimes escape the mouth and show up in the bloodstream—even in people with healthy hearts—suggesting they might travel from your gums to other parts of your body.
Scientists found 11 types of bacteria in the blood that weren’t known to be linked to heart disease or gum problems—and these bacteria were much more or less common in people with early signs of clogged heart arteries than in healthy people.
People with hardened arteries have fewer of certain types of bacteria in their blood than healthy people — and this difference is too big to be just random chance.
Bacteria from gum disease can sometimes show up in your bloodstream, which means they might travel around your body — but just because they’re there doesn’t prove they’re causing heart artery clogging.
