This cat presented with bilateral type II tooth resorption associate with the third mandibular premolars. No periodontal ligament space is discernable. If a distinct space was present or if there were indications that the tooth was nonvital as indicated by a periapical lucency then extraction is indicated. In this case crown amputation and intentional root retention is possible.

No periodontal ligament space is present surrounding the 3rd premolar
The gingiva has proliferated into the crown defect and is painful.
A periosteal elevator is used to expose the tooth and marginal bone and provide space to place the bur without damaging the gingiva.
The bur is angled to allow the air/water spray to splay the gingival margin and expose the bone.
A postop radiograph confirms the marginal bone is smooth.
The defect is sutured using 5-0 monocryl.
