第二型牙齒吸收(TR2)特徵為牙根與齒槽骨融合(強直),牙髓腔消失,牙根逐漸被骨組織取代。X光顯示牙根輪廓不清與骨質融合,僅需移除牙冠,牙根可留置體內。
與TR1同樣常見,常同時存在於不同牙齒
Periodontal disease affects over 80% of dogs by age 3 and is the most common clinical condition. Small and toy breeds are disproportionately affected. Full-mouth dental radiographs under general anesthesia are required for accurate assessment and treatment planning.

監測頻率：術後 24h

可安排定期門診追蹤，屬慢性或自限性病程 (regular outpatient follow-up, chronic or self-limiting course)
預後極佳,牙冠切除後牙根會持續被骨組織取代吸收,通常不會引起併發症。術後疼痛較拔牙輕微,恢復快速。牙根殘留不會造成問題,會自然融合於齒槽骨中。
Diagnostic Approach for Tooth Resorption Type 2
Assess facial symmetry, lymph nodes, halitosis; visual exam of accessible oral structures
Complete dental charting, periodontal probing, assessment of all teeth
Intraoral radiographs of all teeth to evaluate roots, alveolar bone, and periapical regions
