Mouthwash can kill coronavirus within 30 seconds, study finds

Mouthwash could become a vital part of people’s daily routine after laboratory tests found it can kill off coronavirus within 30 seconds.

The initial results of a non-peer-reviewed Cardiff University study showed “promising signs” of mouthwashes containing at least 0.07 per cent cetypyridinium chloride (CPC) being capable of combatting the virus.

Scientists carried out tests at the university’s laboratory by mimicking the conditions of a person’s naso/oropharynx passage and using mouthwash brands including Dentyl.

Their report – titled “The Virucidal Efficacy of Oral Rinse Components Against SARS-CoV-2 In Vitro” – is yet to be peer reviewed but supports another study published last week that found CPC-based mouthwashes are effective in reducing Covid’s viral load.

A clinical trial will next examine how effective over-the-counter mouthwash is in reducing the levels of Covid-19 in the saliva of coronavirus patients at the University Hospital of Wales in Cardiff. The results are expected to be published in early 2021.

Dentyl is the only UK mouthwash brand to have taken part in the 12-week clinical trial, led by Professor David Thomas from Cardiff University.

Dr Thomas told the PA news agency: “Although this in-vitro study is very encouraging and is a positive step, more clinical research is now clearly needed.

“We need to understand if the effect of over-the-counter mouthwashes on the Covid-19 virus achieved in the laboratory can be reproduced in patients, and we look forward to completing our clinical trial in early 2021.”

Dr Nick Claydon, a specialist periodontologist, said he believed the research was “very valuable”.

He added: “If these positive results are reflected in Cardiff University’s clinical trial, CPC-based mouthwashes such as Dentyl used in the in-vitro study could become an important addition to people’s routine, together with hand washing, physical distancing and wearing masks, both now and in the future.”
