Periodontal disease
The four AAHA stages
- Stage 1, gingivitis only. Reversible with professional cleaning and home care.
- Stage 2, early periodontitis. Up to 25% attachment loss, usually visible only on dental radiographs.
- Stage 3, moderate periodontitis. 25–50% attachment loss. Extractions often warranted.
- Stage 4, advanced periodontitis. >50% attachment loss. Extractions, periodontal surgery, or both.
Staging requires general anesthesia, dental probing, and full-mouth dental radiographs, there is no reliable way to stage from an awake oral exam.
Why it is more than 'bad breath'
- Chronic pain, animals are extremely stoic about oral pain; behavior change after dental treatment is often dramatic.
- Oronasal fistula, advanced upper-jaw disease can perforate into the nasal cavity.
- Mandibular fracture, chronic bone loss in small breeds can result in fracture from minor trauma.
- Systemic inflammation, chronic periodontal disease is associated with measurable systemic inflammatory markers and adverse changes in cardiac, hepatic, and renal histopathology.
Prevention that actually works
The gold standard for home care is daily toothbrushing with a pet-safe enzymatic toothpaste, no other home-care intervention matches it for plaque control. Veterinary Oral Health Council (VOHC) accepted dental chews and water additives offer measurable but smaller benefit. Routine professional cleaning under anesthesia at intervals determined by your vet's exam and dental radiographs is the second pillar.
Why it matters
Most cats and dogs over age 3 have some periodontal disease. It is the single highest-yield wellness category most owners under-invest in, partly because the disease is invisible and the pet hides the pain. Daily brushing sounds tedious; it is the cheapest meaningful intervention available.
Frequently asked questions
- Are anesthesia-free dental cleanings a real option?
- AAHA, AVDC, and AVMA all advise against them. They clean only the visible crown surface, miss subgingival disease entirely, do not allow dental radiography, and stress the animal. They are cosmetic, not medical.
- Do dental chews replace brushing?
- No. VOHC-accepted chews reduce plaque and tartar measurably but do not match daily brushing. They are a useful adjunct, not a substitute.
