I was fitted an artificial tooth by the dentist.

牙医给我镶了颗假牙.

It do not have the inherent tradition artificial tooth institute metal snap ring.

它没有传统义齿所固有的金属卡环。

If the diastema is too big, the size harmony is important. A small artificial tooth added in the diastema is not good .

如果缝隙太宽，要注意大小协调，中间加一小塑料牙是不良设计。
