Sometimes the soft tissue of the midline frenum attachment is blamed for the space between the central incisors, but it is hard to be sure whether this is the case. Usually it is advisable to proceed with the tooth movement and determine if there are further problems with retention. If there are, then a frenectomy can be considered if there is excessive tissue bunched up in the midline. Early frenectomy should be avoided.

另外補充一個如果是"上顎正中恆門牙"有Diastema，可以參考課本以下圖片決定
