Diastema

A diastema is considered normal in the primary and mixed dentition as part of normal dental development.

A diastema, or space, between primary or permanent central incisors is often associated with, though not necessarily caused by, a prominent superior labial frenum. The diastema can also be caused by an unerupted supernumerary, or extra tooth. An unwanted diastema persisting after eruption of the permanent canines (ages 10-13) should be evaluated for treatment options such as a frenectomy and/or orthodontic treatment.
