Introduction
Periodontitis increases the risk of heart disease. Chronic oral inflammation allows bacteria and inflammatory substances to enter the bloodstream, continuously stimulating blood vessels and myocardial tissue. Long-standing periodontal infection exacerbates vascular hardening and elevates the risk of various cardiovascular diseases. Recurrent gingival swelling, pain, or oral bleeding warrants prompt medical evaluation and treatment.

Periodontitis increases the risk of heart disease. Chronic oral inflammation allows bacteria and inflammatory substances to enter the bloodstream, continuously stimulating blood vessels and myocardial tissue. Prolonged periodontal infection exacerbates vascular hardening and elevates the risk of various cardiovascular diseases. Recurrent gingival swelling, pain, or oral bleeding warrants prompt medical evaluation and treatment.

Periodontitis is a chronic oral infectious condition characterized by persistent inflammation and ulceration of the gingiva and periodontal tissues. Pathogenic oral bacteria may invade the bloodstream, causing bacteremia. Inflammatory mediators in the blood continuously damage vascular endothelium, accelerate lipid deposition and plaque formation, and progressively lead to vascular sclerosis and lumen narrowing. Treatment includes professional dental cleaning (scaling) and root planing to eliminate infection foci, supplemented by anti-inflammatory medications to control infection.

Chronic periodontal inflammation places the body in a state of persistent low-grade systemic inflammation, disrupting vascular metabolic homeostasis and accelerating the progression of coronary artery disease. In individuals with hypertension or hyperlipidemia, coexisting periodontal disease further hastens cardiac pathology. Timely and definitive treatment of periodontal disease helps reduce systemic inflammatory stimulation and supports cardiovascular health.

Routine oral hygiene—brushing teeth twice daily, cleaning the mouth after meals, and undergoing regular periodontal maintenance—helps sustain a clean oral environment, minimize inflammatory episodes, and mitigate the cumulative adverse impact of oral inflammation on cardiovascular health.
