Cardiff University suggests mouthwash could potentially lower COVID-19 transmissions

Research, led by Cardiff University, suggests that mouthwash has the potential to destroy the outer layer of the Coronavirus and reduce transmission. As a result of the discovery, further research will be carried out to examine if a selection of mouthwashes can envelope the virus, due to previous studies outlining that mouthwash has destroyed similar enveloped viruses.

A member of the Dental Wellness Trust, Dr Saul Konviser, stated: “Whilst we welcome the news, more research is needed into whether normal mouthwash could be effective in reducing COVID-19 transmission in the early stages of infection. If people choose to use a mouthwash, ideally opt for one that contains hydrogen peroxide. Coronavirus is spread through water or mucus droplets from the nose and mouth and saliva containing the virus. It’s therefore essential that people keep their toothbrushes routinely disinfected or sterilised after each use, ideally with hot water and salt or hot water with one added teaspoon of vinegar.”

Professor Martin Addy stated: “Based on the effectiveness of detergent-based handwashing products against coronavirus and because toothpaste contains the same detergents, dental professionals have got behind the suggestion to reaffirm toothbrushing for 2 minutes at least twice a day. These brushings should be before leaving home, particularly if using public transport. For the medical professions, including dentistry, tooth brushing should be performed before donning protective equipment. Increasing the exposure to toothpaste by the general public without the need to brush could be the application of toothpaste on a finger rubbed around the mouth.”
