What are your opinions on mouthwash?


The Huberman Lab discusses the impacts of mouthwash, particularly focusing on the use of antiseptic, alcohol-based mouthwashes. Here are some key points:

  1. Alcohol-Based Mouthwashes: These are generally advised against because they can disrupt the oral microbiome and overall oral health. Antiseptic mouthwashes might be prescribed for severe bacterial infections, but it is important to consult with healthcare professionals about their broader impacts [1 2].

  2. Reducing Nitric Oxide: Alcohol-based mouthwashes can reduce the production of nitric oxide in the oral cavity. This is significant because nitric oxide promotes vasodilation, important for blood vessel health throughout the body, including the oral cavity, throat, nose, brain, and heart [3].

  3. Alternatives to Mouthwash: The discussion also includes alternative oral health practices such as using saltwater rinses, which can be cost-effective and support the healthy oral microbiome without the adverse effects of traditional mouthwashes [4].

In summary, regular usage of traditional antiseptic, alcohol-based mouthwashes is generally discouraged due to their negative effects on the oral microbiome and overall health. Instead, gentler alternatives like saltwater rinses are recommended for maintaining oral health.
