Mouthwash can kills COVID-19 in 30 seconds of exposure to it in a laboratory. According to The New York Post, The preliminary findings — the result of research conducted at Cardiff University — indicate that over-the-counter mouthwashes containing at least 0.07 percent cetypyridinium chloride (CPC) showed “promising signs” of being able to destroy the virus when exposed in a lab setting.
Scientists conducting the study mimicked the conditions of a person’s nasal and oral passages in a test tube, and used common mouthwash brands including Dentyl and Listerine.
While the results show that mouthwash may help kill the virus in saliva, no evidence indicates it is an effective treatment for COVID-19, as it does not reach the respiratory tract or the lungs, according to the BBC.
“If these positive results are reflected in Cardiff University’s clinical trial, CPC-based mouthwashes … could become an important addition to people’s routine, together with hand washing, physical distancing and wearing masks, both now and in the future,” Dr. Nick Claydon, a specialist periodontologist, told the BBC.
Scientists conducted tests in a laboratory mimicking the conditions of a person’s nasopharynx and oropharynx passages, using mouthwash brands such as Dentyl. Reserachers say Venture Life Group, which makes Dentyl, provided information to the study but did not fund it. The same company will fund the next stage of research.
