Scientists have identified bacteria commonly linked to dental plaque inside the arteries and heart tissue of people who experienced serious cardiac events. This finding highlights how oral health can influence systems far beyond the mouth.
When gums become inflamed, tiny openings can allow bacteria to enter the bloodstream. Once circulating, these microbes may contribute to vessel inflammation, potentially accelerating cardiovascular strain and related complications.
Researchers emphasize this does not prove oral bacteria directly cause heart disease, but it strengthens the mouth–heart connection. Maintaining healthy gums through brushing, flossing, and regular dental visits may support overall cardiovascular wellbeing.
