A new study has revealed that Mouthwash can kill COVID-19 within 30 seconds of exposure in a laboratory.
Scientists at Cardiff University found there were “promising signs” that over-the-counter mouthwashes may help to destroy the virus.
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.
Dr Claydon, a specialist periodontologist, said:
“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.”
The university report states that mouthwashes containing at least 0.07% cetypyridinium chloride (CPC) showed “promising signs” of being able to eradicate the virus when exposed to the virus in a lab, the BBC reports.
While the report is yet to be peer reviewed, it supports another recent study which found CPC-based mouthwashes are effective in reducing viral load.
