Periodontal disease is the most common clinical condition in adult dogs and cats. The American Veterinary Dental College (AVDC) classifies it into four stages. Use Dental AI to analyze dental photos and learn periodontal disease staging.
| Stage | Attachment Loss | Probing Depth | Key Findings |
|---|---|---|---|
| Stage 1 (Gingivitis) | 0% | Normal | Erythema, edema, bleeding on probe |
| Stage 2 (Early) | 0–25% | 3–5 mm | Early bone loss, no furcation |
| Stage 3 (Moderate) | 25–50% | 5–7 mm | Furcation involvement, mobility |
| Stage 4 (Advanced) | >50% | >7 mm | Severe bone loss, extraction often needed |
Stage 1 is reversible with professional cleaning and home care. Stages 2–4 involve irreversible attachment loss; the goal is to slow progression and prevent tooth loss where possible.
Dental radiographs are mandatory for staging and treatment planning. Key findings include horizontal and vertical bone loss, furcation radiolucency, root resorption, and periapical lucencies indicating endodontic disease. Without radiographs, you will miss 27% of pathology—bone loss, root fractures, and abscesses are often invisible on oral examination alone.
Comprehensive oral health assessment and treatment (COHAT) requires general anesthesia. There is no safe, effective way to perform subgingival scaling or extractions in a conscious patient. Pre-anesthetic workup should address age-appropriate concerns: bloodwork, imaging for cardiac disease in at-risk breeds.
The procedure includes scaling (ultrasonic and hand), polishing, probing, charting, radiographs, and extractions or other treatments as indicated.
Antibiotics are not routinely indicated for uncomplicated dental procedures; they do not prevent bacteremia and contribute to resistance.
Warning: Never use human toothpaste for pets—xylitol and fluoride toxicity. Daily tooth brushing with pet-specific toothpaste is the gold standard.
Introduce brushing gradually with positive reinforcement. For pets that will not tolerate brushing, alternatives include dental diets, chews, and water additives. Look for products with the Veterinary Oral Health Council (VOHC) seal—these have demonstrated efficacy in reducing plaque and calculus.
VOHC-Approved Product Categories:
- Dental diets: Mechanical and/or chemical plaque control
- Chews: Abrasive action, some with active ingredients
- Water additives: Chlorhexidine or other antimicrobials
- Gels and wipes: Applied to tooth surfaces
No product replaces brushing, but they can help when brushing is not possible. Discuss treatment planning with the Dentistry Specialist.
Recommend dental evaluation for halitosis, pawing at mouth, difficulty eating, drooling, or visible calculus. Most dogs and cats benefit from annual dental exams; small breeds and cats often need more frequent care. Stage 4 disease requires extraction or advanced periodontal surgery—refer to a board-certified dentist when appropriate.
- Stage 1 (gingivitis) is reversible; Stages 2–4 involve irreversible attachment loss.
- Dental radiographs are mandatory—27% of pathology is missed without them.
- COHAT requires general anesthesia; no safe conscious subgingival scaling.
- Daily brushing with pet-specific toothpaste is gold standard; never human toothpaste.
- Look for VOHC seal on dental diets, chews, water additives, gels.
