Could Mouthwash Be Raising Your Blood Pressure? Here’s What Experts Say

Mouthwash is usually seen as a harmless final step in a bathroom routine, but some researchers have been looking at whether certain antibacterial rinses could affect more than breath and plaque. The concern is not that every bottle is dangerous, or that people should panic after using it once.

The question is more specific: whether frequent use of strong antiseptic mouthwash may disrupt helpful bacteria in the mouth that play a role in blood-pressure regulation. Experts say the evidence points to a possible link, especially with repeated use, but it does not prove that mouthwash directly causes high blood pressure.
