Periodontal (gum) disease is a chronic bacterial infection—and its effects extend beyond the mouth.
Research shows that periodontitis triggers a sustained immune response, releasing inflammatory markers such as C-reactive protein (CRP) and cytokines into the bloodstream. These markers are also involved in cardiovascular disease.
When gums are inflamed or bleed, oral bacteria enter the bloodstream (bacteraemia). This contributes to inflammation in blood vessels and affects the inner lining of arteries (endothelium). Over time, this process is linked to the development of atherosclerosis—plaque buildup that narrows arteries and increases the risk of heart attack and stroke.
The New Zealand Dental Association and World Health Organization recognise the established link between oral health and systemic conditions, including cardiovascular disease.
Current research shows that people with severe periodontitis have a higher risk of cardiovascular events, particularly when combined with shared risk factors such as smoking, diabetes and poor diet.
1. Gum infections: Bacteria build up around the gums, triggering inflammation, swelling, and bleeding.
2. Iinflamed gums allow bacteria to enter the bloodstream
3. Bacteria and inflammation can affect blood vessels, contributing to plaque buildup that narrows arteries and restricts blood flow.
4. Narrowed or blocked arteries increase the risk of heart attack and stroke.
Treating gum disease reduces inflammation both in the gums and throughout the body.
Clinical research shows that periodontal therapy lowers systemic inflammatory markers, including C-reactive protein (CRP) and interleukin-6 (IL-6), which are involved in cardiovascular disease. Studies have also shown improvements in endothelial function, meaning blood vessels can better dilate and regulate blood flow after treatment.
In more advanced cases, treatment has also been associated with modest reductions in blood pressure, supporting its role in improving cardiovascular risk markers.
These findings show that reducing oral inflammation has measurable effects on the body’s inflammatory and vascular systems.
Daily oral care remains essential. Brushing twice daily, flossing and regular dental visits help prevent ongoing inflammation.
Lifestyle factors such as smoking, poor diet, stress, and conditions like diabetes can further increase risk and should be managed alongside oral health.
At Dental Holistix, we use Guided Biofilm Therapy (GBT), an evidence-based protocol designed to remove dental biofilm—the primary source of periodontal inflammation—supporting the reduction of inflammatory burden linked to systemic health conditions.
