Overview of Periodontal Disease in Dogs and Cats

A current review summarizes periodontal disease in dogs and cats, including plaque biofilm, gingivitis, attachment loss, bone destruction, clinical staging, prevention, and the need for examination and treatment below the gumline.

What This Means for Different Readers

Three quick summaries of the same article, tailored for different readers.

Bad breath may be the visible edge of disease below the gumline

Periodontal disease begins with plaque biofilm and can progress from gingivitis to loss of attachment and supporting bone. A professional dental procedure may require anesthesia, probing, and dental radiographs to assess hidden roots and bone. Avoid scraping tartar at home or relying on cosmetic cleaning that leaves diseased pockets untreated.

The review explains progression, staging, prevention, and treatment.

Periodontal staging depends on what is found beneath the visible calculus

Client education should separate plaque prevention from treatment of established periodontitis. Anesthesia-free scaling cannot evaluate pockets, obtain diagnostic radiographs, or safely treat subgingival disease. Accurate charting and before-and-after communication improve continuity and home-care adherence.

The review provides a current overview of pathogenesis and management.

Periodontitis is biofilm-driven inflammation with irreversible support loss

Gingivitis is potentially reversible; periodontitis includes attachment and bone loss. Disease severity cannot be inferred from calculus alone. Diagnosis integrates probing, mobility, furcation status, and intraoral radiography. Treatment removes diseased biofilm and nonviable teeth, but long-term control depends on repeated disruption of plaque at home and during follow-up care.

The paper reviews mechanisms, staging, and therapeutic principles.
Why This Matters
Fresh breath is not the goal of periodontal care. The important questions are whether attachment and bone are being lost, whether teeth are painful or mobile, and whether home care is preventing new plaque after professional treatment.
