超過正常數目的額外牙齒。犬正常 42 顆（成犬）、貓正常 30 顆。多生齒可能導致齒列擁擠、食物嵌塞與加速牙周病。
Feline chronic gingivostomatitis (FCGS) causes severe, painful oral inflammation. Treatment includes full-mouth or caudal tooth extraction (60-80% respond), immunomodulatory therapy, and pain management. Feline odontoclastic resorptive lesions (FORLs) are painful and cats often mask signs.
犬偶見。Greyhound 等長頭品種稍多見。

非緊急狀況，但仍建議完整評估以排除其他病因 (non-urgent but complete evaluation recommended)
及時處理預後極佳。不影響整體健康。
Diagnostic Approach for Supernumerary Teeth
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
