A fossa is an irregular depression or concavity.

Lingual fossae are on the lingual surface of incisors.

Central fossae are on the occlusal surface of molars. They are formed by the convergence of ridges terminating at a central point in the bottom of the depression where there is a junction of grooves.

Triangular fossae are found on molars and premolars on the occlusal surfaces mesial or distal to marginal ridges. They are sometimes found on the lingual surfaces of maxillary incisors at the edge of the lingual fossae where the marginal ridges and the cingulum meet.
