Periodontitis is defined as the advanced, irreversible stage of gum disease where the infection spreads beneath the gumline to destroy the periodontal ligament and alveolar bone surrounding the tooth. Unlike gingivitis (which is just inflammation of the gums), periodontitis involves actual structural loss. The attachment between the tooth and the jawbone is eaten away, leading to loose teeth, deep pockets of infection, and tooth loss.
In the Chronic Kidney Disease (CKD) cat, periodontitis represents a constant, high-grade source of systemic inflammation. The ulcerated gum tissues allow bacteria to bypass the body's external defenses and enter the bloodstream directly. This forces the kidneys to constantly filter blood filled with inflammatory markers and bacterial byproducts. This state of chronic inflammation is known to accelerate the progression of kidney scarring (fibrosis). Furthermore, the deep, throbbing pain associated with bone loss often causes "food aversion." The cat approaches the food bowl but runs away, or drops food from their mouth. For a CKD cat, this inability to eat accelerates muscle wasting and weight loss, making the dental condition a priority that must be weighed carefully against the risks of anesthesia.
