Periodontal Disease, Heart Disease and Stroke

Coronary heart disease occurs when fatty proteins and your arteries thicken. This causes the arteries to narrow, constricting blood flow. 

Patients with periodontal infections are more likely to suffer from coronary artery disease than those with healthy mouths. Additionally, patients with periodontal disease may be more susceptible to strokes. A stroke occurs when the blood flow to a part of the brain is suddenly stopped. This may occur, for example, when a blood clot prevents blood from reaching the brain.

Oral bacteria associated with periodontal disease can enter the bloodstream. These bacteria can induce an inflammatory response and a cascade of events that can lead to an increase in white blood cells and C-reactive proteins (CRP). CRP is a protein that has been associated with heart disease. When levels are increased in the body, it amplifies the body’s natural inflammatory response. Bacteria from periodontal disease may enter the bloodstream, causing the liver to produce extra CRP, which then can lead to inflamed arteries and possibly blood clots. Inflamed arteries can lead to blockage, which can cause heart attacks or strokes.

Enacting positive oral hygiene practices and obtaining treatment for periodontal infections may help reduce the risk of developing this condition.
