The MCC study suggests a link between the bacteria in inflamed gums and bone loss—symptoms of chronic periodontitis—and COVID-19 complications. Researchers suggest that patients with high levels of IL-6 (interleukin), a harmful protein that is elevated in gum disease, can be at greater risk of suffering life-threatening respiratory problems.
