The palatal view of this tooth considers the portion of the tooth visible from the side where the tongue would be.
The palatal side of the maxillary central incisor has a small convexity, called a cingulum near the cervical line and has a large concavity, called the lingual fossa.
Along the mesial and distal sides are slightly raised portions called marginal ridges.
The lingual incisal edge is also raised slightly to the level of the marginal ridges.
The lingual fossa is bordered incisally by the lingual incisal edge, mesially by the mesial marginal ridge, distally by the distal marginal ridge, and cervically by the cingulum.
Developmental grooves are found on the cingulum and lying into the lingual fossa.

This side of the tooth tapers in size from the labial side of the tooth.
As a result, the mesial and distal sides of the tooth are further away on the labial side than on the lingual side.
Furthermore, a cross-section of the tooth at the cervical line would show a general triangle appearance.
One of the triangle's sides would be the facial surface, and the other two sides would be the mesial side and the slightly shorter distal side.
