五歲米克斯母犬因啃咬大骨，造成牙齒斷裂，來本院進行根管治療(Endodontics，俗稱「抽神經」)及加裝3D列印的金屬牙冠，使用狀況良好，飼主亦幫狗狗確實刷牙，沒有牙齦炎及牙周病。

提醒各位飼主幫狗貓刷牙時，務必刷至牙齦與牙齒接界處(牙齦溝，gingival sulcus)，才能確實將牙菌斑刷除。

A five-year-old mixed female dog had broken her teeth due to gnawing on the bone, she came to our hospital for endodontics and 3D printing metal crowns. The crowns are in good condition, the owner has brushed her teeth carefully, and found no gingivitis and periodontal disease.

It is very important that the owner must brush to the junction of gingiva and teeth (gingival sulcus) when brushing the teeth of dogs and cats, so as to really remove plaque.
