Is mouthwash bad for heart? Here’s what research actually says

EXETER (UK): (Apr 19) Social media videos are claiming that mouthwash can raise the risk of high blood pressure – and potentially damage heart health.

According to some of these videos, this is caused by mouthwash wiping out “good” oral bacteria that are important for the cardiovascular system. While it’s a striking message, don’t throw your mouthwash away just yet. The reality is far more complex.

Our mouths contain a wide variety of bacteria. Together, these bacteria form a balanced and diverse microbiome which helps prevent the overgrowth of other bacteria linked to disease, supports normal metabolic functions and contributes to both good oral and overall health.
