Mouthwash – a popular oral hygiene product
Almost every household can find mouthwash for daily oral hygiene. Softening agents for softening chlorhexidine, however, destroy the important oral flora and thus also increase blood pressure, according to a study in the United States.
Chlorhexidine – useful or not?
Chlorhexidine, which is commonly used in mouthwash, is an antiseptic that can destroy not only harmful bacteria but also useful oral flora and thus cause hypertension. One of the tasks of these beneficial bacteria, for example, is the regulation of blood pressure. Researchers at the University of Texas and the Baylor University Medical School in Houston have shown in a recent study how chlorhexidine also increases blood pressure. The study was published in Frontiers in Cellular and Infection Microbiology.
Good luck with chlorhexidine
Chlorhexidine adheres to the teeth and mucous membranes of the oral cavity very long, thus explaining its long-lasting effect. Because of the antibacterial property, caries and dental plaque have to be prevented. When chlorhexidine is administered for at least four weeks, dental records are successfully reduced. However, whitening tooth infusions have only improved to a very small extent, with no stronger improvement in the oral cavity.
Side effects of chlorhexidine
Chlorhexidine contained in mouthwash often can lead to decolorization of the teeth when used for more than four weeks, sometimes to tartar, temporary damage to the taste and damage to the oral mucosa. Therefore, mouth rinsing agents containing chlorhexidine are not suitable for long-term use.
Mouthwashes can increase blood pressure
Certainly, chlorhexidine not only damages the oral mucosa itself but also the beneficial bacteria that make up our oral flora, including obviously those that would normally help maintain blood pressure at a normal and healthy level as shown in the study.
Researchers from the University of Texas and the Baylor University Medical School in Houston have shown that chlorhexidine destroys these beneficial bacteria in the oral flora involved in the conversion of nitrates to nitric oxide. Nitrogen oxide, in turn, is a signal molecule that maintains stable blood pressure. In the absence of these beneficial bacteria, the regulatory nitrogen oxide is also absent and the blood pressure is increased.
When does the blood pressure increase?
After only one week, the study mentioned that twice a day mouthwash with chlorhexidine changed the flora of the oral cavity and, at the same time, blood pressure. Surveys of saliva and tongue pads have been sampled several times in the study. Also, blood pressure is measured regularly, at the beginning of the study, and finally. Researchers report that systolic blood pressure in their patients increased significantly in only one week. Only after the mouth stops, the oral flora can be regenerated again, again adjusting the blood pressure, because the beneficial bacteria producing nitric oxide in the oral flora can now be colonized and multiplied.
New approach to treatment of hypertension
This new finding is of immense importance for millions of hypertensive patients worldwide, especially since two out of three of these patients still have too high blood pressure despite lowering blood pressure without knowing exactly what it is. Thanks to this study, it would now be possible to include the oral flora in the treatment of high blood pressure and to take measures to help restore the flora of the oral gland so that the oxides producing bacteria can be colonized . Of course, healthy eating is one of the requirements of an intact oral flora.
Adjustment of blood pressure through nitric oxide
According to the researchers, nitric oxide is one of the most important signaling molecules in the human body. Therefore, it occurs almost anywhere in the body, and even nitric oxide produced in the oral cavity can perform many other important health-related tasks in addition to regulating blood pressure. Therefore, antiseptic rinsing of the mouth, which millions of people use every morning, unfortunately is a habit that makes more harm than desired. (Fm)
