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

Torus palatinus is excess bone growth and occurs in the midline of the hard palate. It may

teeth. In an edentulous person, the vestibule would extend between the lips or cheeks and the
