The World Health Organization says there is no evidence that mouthwash could protect you from coronavirus.
A report suggested that mouthwash could damage the virus and prevent infection, with scientists calling for more research.
But a WHO spokesperson said, “There is no evidence that using mouthwash will protect you from infection with the new coronavirus.”
Researchers say research needs to be done into whether mouthwash can destroy the “coat” of the virus, preventing it from multiplying.
Lead author Professor O’Donnell, co-director of Cardiff University’s Systems Immunity Research Institute said, “In test-tube experiments and limited clinical studies, some mouthwashes contain enough known virucidal ingredients to effectively fight lipids in similar enveloped viruses.
“What we don’t know yet is whether existing mouthwashes are active against the lipid membrane of SARS-CoV-2 (Covid-19).
“Our literature review suggests urgent research is needed to determine the potential for use against this new virus.”
Researchers say mouthwash chemicals chlorhexidine, cetylpyridinium chloride, hydrogen peroxide and povidone iodine have the potential to prevent infections.
WHO added, “Some brands of mouthwash can remove certain microbes in the saliva in your mouth for a few minutes
However, this does not mean that they protect you against 2019 nCoV infection.
