The Claim
Oral microbiome composition is associated with cardiovascular disease risk.
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.
The types and amounts of bacteria in the mouth are linked to the likelihood of developing cardiovascular disease.
See the scientific wording
Oral microbiome composition is associated with cardiovascular disease risk.
Bad bacteria from the mouth enter the bloodstream through damaged gum tissue, travel to blood vessel walls, and trigger chronic inflammation. This inflammation damages the inner lining of blood vessels, reduces their ability to relax, and causes fats to build up into unstable plaques. These plaques can rupture and block arteries, causing heart attacks or strokes.
What the research says
2 studiesStudy: An oral microbiome model for predicting atherosclerotic cardiovascular disease
Scientists found that certain types of bacteria in the mouth are more common in people who later have heart problems, and using this info helps predict heart disease better than just checking age or blood pressure alone.
The study shows that bad bacteria in the mouth, especially when gums are inflamed, can travel into the blood and cause inflammation that harms the heart and blood vessels, making heart disease more likely.
