Research overview: periodontal disease prevalence in cats

Periodontal disease, the inflammation and destruction of tissues supporting the teeth driven by plaque bacteria, is extremely common in adult cats and a leading reason for dental intervention, progressing from gingivitis to attachment loss and potential tooth loss if untreated. Beyond local effects, chronic oral infection and inflammation may have systemic health implications. This overview compiles the dental literature rather than one source, describing how plaque and the host response drive periodontal breakdown, why prevalence rises with age, and how professional cleaning, extraction of affected teeth, and home care manage the disease. It matters because periodontal disease is a widespread, often underappreciated source of pain and infection in cats, and its prevention and treatment are central to feline dental and overall health.
