Mouthwash Can Kill Coronavirus in 30 Seconds in Lab Tests, Study Finds

Mouthwash CAN ERADICATE coronavirus within 30 seconds of laboratory exposure, according to a scientific study.

The preliminary result comes ahead of a clinical trial on whether the use of over-the-counter mouthwashes has the potential to reduce levels of Covid-19 in a patient’s saliva.

The Cardiff University report said that mouthwashes containing at least 0.07% cetypyridinium chloride (CPC) showed “promising signs” of being able to combat the virus.

The report, The Virucidal Efficacy of Mouthwash Components Against SARS-CoV-2 In Vitro, has yet to be peer-reviewed, but it supports another study published last week that found CPC-based mouthwashes to be effective in reducing Covid viral load.

The latest test was performed by scientists in the university lab and mimicked the conditions of a person’s naso / oropharyngeal passage using mouthwash brands like Dentyl.

Next, a clinical trial will examine the efficacy of mouthwash in reducing the viral load in the saliva of Covid-19 patients at the University Hospital of Wales in Cardiff, and its results will be published in the early part of 2021.

Dentyl is the only UK mouthwash brand to participate in the 12-week clinical trial, led by Professor David Thomas of Cardiff University and entitled: “Measuring the antiviral activity of mouthwash against Covid-19” .

Dr Thomas told the Palestinian Authority news agency: “While these mouthwashes eradicate the virus very effectively in the laboratory, we need to see if they work in patients and this is the goal of our ongoing clinical study. .

“It is important to note that the study will not give us any direct evidence on viral transmission between patients, which would require a different type of study on a much larger scale.

“However, the ongoing clinical study will show us how long the effects last after a single administration of the mouthwash in patients with Covid-19.”

He added: “Although this in vitro study is very encouraging and a positive step, more clinical research is clearly needed now.

“We need to understand whether the effect of OTC mouthwashes on the Covid-19 virus achieved in the laboratory can be replicated in patients, and we hope to complete our clinical trial in early 2021.”

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

He said: “If these positive results are reflected in the Cardiff University clinical trial, CPC-based mouthwashes like the Dentyl used in the in vitro study could become an important addition to people’s routine, along with with hand washing, physical distance and the use of masks “both now and in the future.”
