A new study has found that coronavirus is killed within 30 seconds of coming into contact with regular mouthwash. This study, which is being carried out by Cardiff University says that mouthwashes containing at least 0.07% CPC show ‘promising signs’ for fighting the virus – with Dentyl being the only UK mouthwash brand to take part in the 12-week clinical trial, led by Professor David Thomas.
While the report is yet to be peer-reviewed, it does however support another study published last week, which found CPC-based mouthwashes are effective in reducing Covid’s viral load.
The preliminary result comes ahead of a clinical trial into whether using over-the-counter mouthwash has the potential to reduce Covid-19 levels in saliva. This trial will next examine the effectivity which mouthwash has, to reduce the viral load in the saliva of Covid-19 patients, currently hospitalised at the University Hospital of Wales in Cardiff – with results expected in 2021.
Professor Thomas told the PA News Agency: ‘It is important to point out the study won’t give us any direct evidence on viral transmission between patients, that would require a different type of study on a much larger scale. The ongoing clinical study will, however, show us how long any effects last, following a single administration of the mouthwash in patients with Covid-19.’
This effectively means that apart from masks, hand-hygiene and social distancing, we could add ‘use mouthwash regularly’ as another mitigation measure until a vaccine is made available.
