ORAL BACTERIA CAN TRAVEL TO THE HEART 🫀
Recent research has revealed a striking connection — bacteria commonly found in dental plaque have been detected inside the arteries and even heart tissue of patients who suffered heart attacks.
How does this happen?
When gums are inflamed or infected, bacteria can enter the bloodstream through microscopic openings in the gum tissue. Once circulating, they may trigger inflammation inside blood vessels, accelerating vascular injury and contributing to heart problems.
This doesn’t mean oral bacteria directly cause heart disease — but their presence highlights how closely oral and cardiovascular health are intertwined. Ignoring gum health can silently add to systemic risks far beyond the mouth.
Maintaining healthy gums through regular brushing, flossing, and professional cleanings isn’t just about preventing tooth loss — it could also play a role in protecting the heart.
