快5岁的小孩要不要做根管治疗和牙冠?
Depending on teeth. some baby teeth will be replaced till 12 years old. It
is necessary to do Pulpotomy and Crown (SSC) to save the teeth till
permanent teeth grow up. Otherwise, in most case, early loss baby teeth can
cause the space deficiency, the permanently teeth had no space to grow.
据说上了牙冠之后很容易掉,是这样吗?
No.
还有门牙是不是就不用补了?好象门牙六七岁就要换了。
depending on age and the cavity. at 5 years old, since baby central incisor
门牙 will be replaced around 7 years old, if decay is tiny or no symptom,
and no infection, keep clean, observation, and regular check up will be fine
