Simple oral hygiene measures could help lower the risk of transmission of the novel coronavirus from the mouth to the lungs, and help prevent severe instances of COVID-19, according to a study. The research published in the Journal of Oral Medicine and Dental Research, shows that there is emerging evidence that specific ingredients of some inexpensive and widely available mouthwash products are highly effective at inactivating the SARS-CoV-2 virus that causes COVID-19. Evidence shows that blood vessels of the lungs, rather than airways, are affected initially in COVID-19 lung disease with high concentrations of the virus in saliva and periodontitis associated with increased risk of death. The researchers propose that dental plaque accumulation and periodontal inflammation further intensify the likelihood of the SARS-CoV-2 virus reaching the lungs and causing more severe cases of the infection. Experts say this discovery could make effective oral healthcare a potentially lifesaving action -- recommending that the public take simple, but effective, daily steps to maintain oral hygiene and reduce factors contributing to gum disease, such as the build-up of plaque. Initial observations of lung CT scans from patients suffering from COVID-19 lung disease led to collaboration between medical and dental researchers on the potential entry route into the bloodstream.

"This model may help us understand why some individuals develop COVID-19 lung disease and others do not," said study co-author Iain Chapple, Professor at the University of Birmingham in the UK. The researchers noted that gum disease makes the gums leakier, allowing microorganisms to enter into the blood. Simple measures such as careful tooth brushing and interdental brushing to reduce plaque build-up, along with specific mouthwashes, or even saltwater rinsing to reduce gingival inflammation could help decrease the viral concentration in saliva. This can also help mitigate the development of lung disease and reduce the risk of deterioration to severe COVID-19, according to the researchers. The new model is based on the mouth providing a breeding ground for the virus to thrive, with any breach in oral immune defences making it easier for the virus to enter the bloodstream.
