A diastema is a space or gap between two teeth. It appears most often between the two upper front teeth. However, gaps can occur between any two teeth. A mismatch between the size of the jaw bones and the size of the teeth can cause either extra space between teeth or crowding of teeth.ometimes some teeth are missing or undersized. This happens most often with the upper lateral incisors (the teeth next to the two upper front teeth). That can cause the upper central incisors to develop a space. A diastema also can be caused by an oversized labial frenum.
