A growing body of research, including a study from Osaka University Hospital, suggests that oral hygiene plays an important role in cardiovascular health.
When teeth are not brushed regularly—especially at night—harmful bacteria can multiply in the mouth and cause gum inflammation.
These bacteria can enter the bloodstream through inflamed or bleeding gums and travel to the heart and blood vessels.
Over time, this process may contribute to chronic inflammation and increase the risk of cardiovascular disease.
The findings from Osaka University highlight how a simple daily habit like brushing your teeth can support long-term heart health.
