Study Discovers Biological Imbalance is the Link Between Gum and Kidney Disease by Colleen Fleiss on January 9, 2021 at 2:15 AM A new study has revealed that an imbalance of the body's oxygen-producing free radicals and its antioxidant cells could be the reason why gum disease and chronic kidney disease affect each other. Periodontitis - or gum disease - is a common, inflammatory disease which causes bleeding gums, wobbly or drifting teeth and can eventually result in tooth loss. Previous studies have shown a link between the severe oral inflammation caused by gum disease and chronic kidney disease (CKD) which demonstrated that those with worse inflammation of the gums have worse kidney function.
