A recent study has shown that using mouthwash regularly can raise the risk of hypertension. Read this article to know how.
Mouthwash is a common oral hygiene product used by millions of people daily to keep their breath fresh and mouths clean. However, recent research has suggested a surprising and concerning link between regular mouthwash use and hypertension (high blood pressure).
If you regularly use mouthwash, this article is definitely for you. Read on to find out how mouthwash might contribute to hypertension.
The Science Behind Mouthwash and Hypertension
While mouthwash helps in reducing bad breath and preventing cavities, it contains an antiseptic ingredient called chlorhexidine, which may kill nitric oxide (NO)-producing bacteria. Dr. Santosh Hedau, Consultant Nephrologist at CARE Hospitals Banjara Hills, Hyderabad, explains, “The killing of these bacteria may raise systolic blood pressure.”
How Nitric Oxide Affects Blood Pressure
Nitrates, found in certain foods like beetroots, are known to reduce blood pressure. Dr. Pirzada elaborates, “Nitrates are converted by millions of tiny oral microbiomes into nitrites, which are further reduced to NO in our body. NO is a vasodilator, hence it helps in reducing blood pressure.”
When mouthwash kills these beneficial bacteria, the production of nitrites decreases, leading to lower levels of nitric oxide. This reduction can result in blood vessels constricting more, which can increase blood pressure.
Research Findings on Mouthwash and Hypertension
A study published in Free Radical Biology and Medicine found that participants who used mouthwash twice daily experienced a significant increase in blood pressure compared to those who did not use mouthwash. The increase was enough to suggest a potential risk of developing hypertension over time.
The Broader Implications of Hypertension
Hypertension is a major public health concern, affecting over a billion people worldwide, according to the World Health Organization. It is one of the leading factors for cardiovascular diseases, including strokes and heart attacks.
The potential connection between mouthwash and hypertension highlights the importance of being aware of the products we use daily. While mouthwash can be beneficial for oral hygiene, its potential impact on blood pressure should not be ignored.
Precautionary Measures
Doctors provides some precautionary measures for those who use mouthwash regularly:
- Avoid for Young Children: Mouthwash is not recommended for kids below 8 years of age.
- Do Not Swallow: Ensure not to swallow mouthwash.
- Timing: Refrain from eating food 30 minutes before and after using mouthwash.
- Alternatives: Consider frequent water sipping, chewing sugarless candies, avoiding alcohol-based mouthwashes, and maintaining good oral hygiene by brushing twice a day.
- Blood Pressure Considerations: Patients with blood pressure higher than 140/90 should use diluted mouthwash or avoid it if possible.
- Dental Hygiene: Regular dentist visits and the use of floss after meals can reduce bad breath and prevent food particles from accumulating in dental spaces.
Conclusion
While more research is needed to fully understand the relationship between mouthwash and hypertension, the existing evidence suggests there is a potential link. Consumers should be aware of this and take steps to mitigate the risk, such as moderating mouthwash use and choosing alternative products. By staying informed and making conscious choices, individuals can better manage their oral health without compromising their cardiovascular health.
