The Surprising Connection Between Mouth Rinses and Blood Pressure—What Patients Should Know

As a dentist serving both Schererville and Chicago, we’re dedicated to informing our patients about how oral health affects their entire body. Recently, there’s been compelling evidence suggesting that the antiseptic mouth rinses many people use could have a surprising effect on blood pressure.

At the heart of the issue is a molecule called nitric oxide (NO). NO plays a crucial role in cardiovascular health by relaxing blood vessels and reducing blood pressure. Interestingly, part of the body’s NO production happens in the mouth through bacteria that convert dietary nitrates into nitric oxide. This helps regulate vascular health and keep blood pressure in check.

However, some mouth rinses can interfere with this process. Antiseptic rinses, like those containing chlorhexidine or cetylpyridinium chloride, kill oral bacteria. While this can reduce bad breath and prevent gum disease, it may also lower the production of NO, potentially raising blood pressure. A recent study found that mouth rinses could increase systolic blood pressure by a few points after just one use.

This doesn’t mean you should completely abandon mouth rinses, but rather be selective about the products you choose. Not all mouthwashes have the same impact. There are alternatives that can support oral health without disrupting NO levels, such as coconut oil-based rinses or StellaLife’s coconut rinse. These options are gentler on the beneficial bacteria that aid in nitric oxide production, ensuring that your cardiovascular system remains supported.

For patients with high blood pressure, particularly those in Schererville and Chicago, it’s worth reconsidering the daily use of strong antiseptic mouthwashes. Talk to your dentist about alternatives or other oral hygiene practices that can maintain your oral health without putting strain on your heart.
