Can a healthy mouth reduce the likelihood of getting a viral infection, i.e. COVID?

The short answer is… YES! According to a study out from the University of Louisville Dental school, there are proteins produced by oral epithelial cells which protect humans against viruses entering the body through the mouth. These oral bacteria can suppress the activity of these cells, increasing vulnerability to infection. Specifically, certain pathogenic bacterial species, such as P. gingivalis, which cause periodontal disease, can completely suppress interferon production and severely enhance susceptibility to viral infection.

Just another reason to take care of your oral health and gums!
