Studies Show Mouthwash Could Slow Coronavirus Spread

Gargling with mouthwash might not only prevent tooth and gum decay, but could also slow the spread of the novel coronavirus.

Certain types of mouthwash appear to deactivate the coronavirus in the mouth, some studies have shown, but some researchers question whether the findings will impact real-life transmission.

Scientists at Cardiff University announced several weeks ago that there were “promising signs” that the use of a mouthwash may help destroy the coronavirus, although it would serve as a treatment for those with the virus, not a means to ward off the virus.

The researchers found that two Dentyl products containing cetylpyridinium chloride and the Listerine Advanced mouthwash containing ethyl lauroyl arginate “eradicated the virus completely after a 30-second treatment.”  The use of the correct mouthwash might prove useful in reducing the spread of the virus because the mouthwash dissolved the outer protective layer of virus particles, preventing them from attaching to cells and infecting them since Covid-19 is spread from the aerosols and droplets generated when an infected person sneezes, coughs, or talks.

Two makers of mouthwash, Unilever and Colgate-Palmolive, are cautiously starting to spread the message to consumers and dentists, although more research and human trials are still needed to validate the findings.
