Stage 3: Established Periodontal Disease

Stage 3 periodontal disease is characterized by a 25%–50% loss of a tooth's support.

Gingival recession
Slightly less than 50% bone loss


Treatment Options in Cases of Gingival Recession (Gum Loss)

  • If a pet owner is willing to administer home care as listed in Stage 1, periodically follow up to monitor plaque control efforts.

  • If a pet owner is not willing to administer home care, the tooth should be extracted.

Surgical Treatment for Stage 3 Periodontal Pocket

Apical reposition flap


Stage 3–4 periodontal disease with 10 mm pocket


Parallel incisions for exposure
Curette used to remove root calculus


Gum tissues sutured lower to remove the pocket


Stage 3 Palatal Defect Surgical Treatment

Before surgery, a periodontal probe is placed on the inside surface of the left upper canine. Surgery should be performed when the probing depth exceeds 4 mm but does not extend to the nasal cavity.

Apply bone implant to decrease pocket depth.
