Mouthwash and Heart Health

Published Apr 26, 2026 7:30 PM �� By Dev Malhotra

As we strive to maintain good oral hygiene, mouthwash has become a staple in many of our daily routines. However, recent social media videos have sparked concern that mouthwash may be doing more harm than good, particularly when it comes to our heart health. The claims suggest that mouthwash can raise blood pressure, potentially leading to damage to our hearts. But is there any truth to these claims?

To understand the potential risks, it's essential to look at the ingredients commonly found in mouthwash. Many mouthwashes contain antibacterial ingredients such as chlorhexidine, which can help reduce plaque and gum inflammation. However, some research has suggested that these ingredients may also have a negative impact on our cardiovascular system. Studies have shown that the use of chlorhexidine mouthwash can lead to an increase in blood pressure in some individuals.

So, what does this mean for our heart health? High blood pressure is a significant risk factor for heart disease, and any potential increase in blood pressure is a cause for concern. However, it's essential to note that the current evidence is limited, and more research is needed to fully understand the relationship between mouthwash use and heart health. The American Heart Association recommends maintaining good oral health, but also emphasizes the importance of monitoring blood pressure and overall cardiovascular health.

In addition to the potential risks, there are also some benefits to using mouthwash. Reducing plaque and gum inflammation can help prevent gum disease, which has been linked to an increased risk of heart disease. Furthermore, mouthwash can also help kill bacteria that can cause bad breath and other oral health issues. To minimize any potential risks, it's recommended to choose a mouthwash that is low in alcohol and does not contain harsh chemicals.

For those concerned about the potential risks, there are some alternative options available.

  • Saline mouthwash: A saline mouthwash can be a gentle and effective alternative to traditional mouthwashes.
  • Essential oil mouthwash: Some essential oils, such as tea tree oil, have antibacterial properties that can help reduce plaque and gum inflammation.
  • Homemade mouthwash: Making your own mouthwash at home using ingredients such as water, salt, and baking soda can be a cost-effective and chemical-free alternative.

In conclusion, while the current evidence suggests that mouthwash may have some potential risks, it's essential to weigh these risks against the benefits. By choosing a mouthwash that is low in alcohol and harsh chemicals, and monitoring our blood pressure, we can help minimize any potential risks and maintain good oral and heart health. As with any health-related concern, it's always best to consult with a healthcare professional for personalized advice and guidance.
