NEW STUDY found that mouthwashes containing the ingredient cetylpyridinium chloride ‘show promising signs’ of reducing COVID-19 in saliva, according to lab tests:

Dr. Tammy Penhollow is available to talk about this. Below are details of what she can say:

Oral health is one of the first lines of defense in many major illnesses. It may seem so simple, but a look at oral health is actually a predictor of overall health. The mouth is the entry point for the respiratory and digestive tracts.  

As such, the first line of defense against COVID-19 infection may be . . . your mouth.

1)  Normally, the body’s natural defenses along with good oral care (including daily brushing and flossing) keep bacteria under control. Without good oral hygiene, tooth decay, gum disease, and oral infections can occur. 

2) Many common medications such as opioid painkillers, decongestants, allergy pills, and diuretics reduce production of saliva. Saliva is important in neutralizing acids produced by oral bacteria, and in washing away food, both of which protect you from microbes that lead to disease. 

3) Oral bacteria and the inflammation associated with severe gum disease may play a role in certain diseases such as diabetes, HIV, cardiovascular disease—and these can reduce the ability to fight infection.

4) In the case of coronavirus, the throat and salivary glands in the mouth are important sites of virus replication and transmission in early COVID-19. The virus is an enveloped virus—outer membrane that derives from the host cell from which it buds. Mouthwash components including ethanol, chlorhexidine, cetylpyridinium chloride, hydrogen peroxide, and povidone-iodine disrupt that viral envelope.

5) This knowledge can be extrapolated to OTHER coronavirus strains because the lipid envelope does not vary when viruses mutate.  

While this is not a cure, and we recommend clinical trials to test the effectiveness of this approach in prevention of coronavirus illness, simple gargling (not swallowing) mouthwash with one of these ingredients may be yet another weapon that we can employ. 

Studies on mouthwash and the prevention of contracting the Coronavirus are promising, however people should continue to follow the safety protocols set forth by the CDC and practice proven preventive measures—washing hands frequently, maintaining social distance, and mask wearing.
