The '''mandibular lateral incisor''' is the [[tooth]] located distally (away from the midline of the [[face]]) from both [[mandibular central incisor]]s of the [[mouth]] and mesially (toward the midline of the face) from both [[mandibular canine]]s.  As with all [[incisor]]s, their function is for [[Shearing (physics)|shearing]] or cutting food during [[mastication]], commonly known as chewing.  There are no [[cusp (dentistry)|cusp]]s 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 teeth|deciduous]] (baby) mandibular lateral incisor and that of the [[permanent teeth|permanent]] mandibular lateral incisor.

In the [[Universal numbering system (dental)|universal system of notation]], the deciduous mandibular lateral incisors are designated by a letter written in uppercase.  The right deciduous mandibular lateral incisor is known as "Q", and the left one is known as "N".  The [[FDI World Dental Federation notation|international notation]] has a different system of notation.  Thus, the right deciduous mandibular lateral incisor known as "82", and the left one is known as "72".

In the universal system of notation, the permanent mandibular lateral incisors are designated by a number.  The right permanent mandibular lateral incisor is known as "26", and the left one is known as "23".  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 lateral incisors would have the same number, "2", 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 lateral incisor is known as "42", and the left one is known as "32".
