The permanent maxillary central incisor is the widest tooth mesiodistally in comparison to any other anterior tooth. It is larger than the neighboring lateral incisor and is usually not as convex on its labial surface. As a result, the central incisor appears to be more rectangular or square in shape.
For example, if a drill bur would be inserted into a tooth from any side (proximal, vestibular, oral), the depth of the hole is defined from the axial wall of the hole (from the long axis walls (vertical surfaces bounding the tooth)). [1] Buccal

The maxillary teeth are the maxillary central incisors (teeth 8 and 9 in the diagram), maxillary lateral incisors (7 and 10), maxillary canines (6 and 11), maxillary first premolars (5 and 12), maxillary second premolars (4 and 13), maxillary first molars (3 and 14), maxillary second molars (2 and 15), and maxillary third molars (1 and 16).
Incisors are divided further into central and lateral incisors. Among premolars and molars, there are first and second premolars, and first, second, and third molars. The side of the mouth in which a tooth is found may also be included in the name. For example, a specific name for a tooth may be "permanent maxillary left lateral incisor."
There are 20 primary teeth and they typically erupt in the following order: (1) central incisor, (2) lateral incisor, (3) first molar, (4) canine, and (5) second molar. [13] As a general rule, four teeth erupt for every six months of life, mandibular teeth erupt before maxillary teeth, and teeth erupt sooner in females than males. [14]

Mamelons are present on permanent central and lateral incisors. Mamelons are easiest to observe on the maxillary central incisors, and appear as three small prominences on the incisal edge of the tooth. [2] Mamelons are ordinarily of no clinical importance. [3] Usually, they are worn off early in the life of the tooth. [medical citation needed]
