What is periodontal disease staging?
Periodontal disease staging is a standardized four-level grading system veterinarians use to classify the severity of gum and tooth disease in pets, from mild inflammation to advanced bone loss.
Vets in Denver use a four-stage classification system to assess periodontal disease, the inflammatory condition affecting a pet's gums and tooth-supporting structures. Stage 1 involves mild gum inflammation with no bone loss. Stage 2 includes gum recession and loss of less than 25% of the bone supporting the tooth. Stage 3 shows moderate periodontitis with 25-50% bone loss and deeper pockets between the gum and tooth. Stage 4 represents severe disease with more than 50% bone loss, often requiring tooth extraction.
This staging system matters because it guides treatment decisions and helps pet owners understand disease progression. Early-stage disease (1-2) typically responds to professional cleaning and improved home care, while advanced stages (3-4) often require extraction, antibiotics, or specialized periodontal therapy. Identifying the stage during a veterinary exam determines whether a tooth can be saved or should be removed, and it informs the urgency of treatment. Dogs and cats with untreated periodontal disease face chronic pain, difficulty eating, and potential systemic infections that can affect the heart, kidneys, and liver. Regular dental exams allow vets to catch disease early, when intervention is less invasive and more cost-effective. Veterinary dental specialists in Denver can diagnose and manage all stages of periodontal disease.
