Mandibular central incisor
Mandibular central incisors of permanent and primary teeth marked in red.

The mandibular central incisor is the tooth located adjacent to the midline of the face and is mesial (toward the midline of the face) from both mandibular lateral incisors. As with all incisors, their function is for shearing or cutting food during mastication, commonly known as chewing. There are no cusps on the teeth. Instead, the surface area of the tooth used in eating is called an incisal ridge or incisal edge. Though relatively the same, there are some minor differences between the deciduous (baby) mandibular central incisor and that of the permanent mandibular central incisor.

In the universal system of notation, the deciduous mandibular central incisors are designated by a letter written in uppercase. The right deciduous mandibular central incisor is known as "P", and the left one is known as "O". The international notation has a different system of notation. Thus, the right deciduous mandibular central incisor is known as "81", and the left one is known as "71".

In the universal system of notation, the permanent mandibular central incisors are designated by a number. The right permanent mandibular central incisor is known as "25", and the left one is known as "24". In the Palmer notation, a number is used in conjunction with a symbol designating in which quadrant the tooth is found. For this tooth, the left and right central incisors would have the same number, "1", but the right one would have the symbol, "┐", over it, while the left one would have, "┌". The international notation has a different numbering system than the previous two, and the right permanent mandibular central incisor is known as "41", and the left one is known as "31".
