The Claim

Oral pathogens such as Porphyromonas gingivalis and their virulence factors, including gingipains and lipopolysaccharide, are detected in the bloodstream and vascular tissues of individuals with periodontitis and are associated with direct endothelial damage and activation of pro-inflammatory pathways.

Source: Dysbiosis of the oral microbiome and cardiovascular risk; from endothelial dysfunction to systemic inflammation

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Bacteria from gum disease, including Porphyromonas gingivalis and its toxic molecules, are found in the blood and blood vessel walls of people with periodontitis and are linked to injury of the blood vessel lining and activation of inflammatory signals.

See the scientific wording

Oral pathogens such as Porphyromonas gingivalis and their virulence factors, including gingipains and lipopolysaccharide, are detected in the bloodstream and vascular tissues of individuals with periodontitis and are associated with direct endothelial damage and activation of pro-inflammatory pathways.

Why this might work

Bacteria from infected gums enter the blood, invade blood vessel walls, and release toxins that break down protective molecules and trigger inflammation. These toxins also activate immune sensors on blood vessel cells, causing them to produce more inflammatory signals and attract immune cells. This damages the inner lining of blood vessels, reduces their ability to relax, and promotes plaque buildup and rupture.
