Gingivitis is defined as the inflammation of the gingiva, or gum tissue, surrounding the teeth. It is the earliest and only reversible stage of periodontal disease, caused primarily by the accumulation of bacterial plaque along the gumline. The cat's immune system reacts to these bacteria, causing the gums to become red, swollen, and prone to bleeding upon contact. For the Chronic Kidney Disease (CKD) cat, this condition presents a significant medical risk beyond just oral health. The inflamed, bleeding gum tissue acts as an open door for oral bacteria to enter the bloodstream (bacteremia). These circulating bacteria are filtered by the kidneys, where they can lodge and cause a severe infection (pyelonephritis), further destroying renal function. Additionally, the chronic inflammation creates a constant low-grade stress on the immune system. Clinically, the oral pain can also discourage eating, contributing to anorexia and weight loss. Management relies on reducing plaque through brushing (if tolerated) or professional veterinary cleaning, though the anesthesia risk must be carefully weighed against the benefit of infection control.
