A space, or lack of contact area, between any two teeth in the same arch is called a diastema.
g g g g g g g g g g g g g g g g g g
When a diastema occurs between the maxillary central incisors, it is often the result of a
g g g g g g g g g g g g g g g g
pronounced labial frenum extending to the crest of the alveolar ridge and possibly over the
g g g g g g g g g g g g g g g
ridge. This band of firm connective tissue causes the erupting incisors to be pushed aside
g g g g g g g g g g g g g g g
resulting in a diastema, or space. Correction of a diastema usually involves surgical removal,
g g g g g g g g g g g g g g
or cutting, of the frenal tissue between teeth.
