Maxillary lateral incisor
the second upper tooth from the dental midline on both sides of the mouth
The maxillary lateral incisors are a pair of upper (maxillary) teeth that are located laterally (away from the midline of the face) from both maxillary central incisors of the mouth and medially (toward the midline of the face) from both maxillary canines. As with all incisors, their function is for shearing or cutting food during mastication, commonly known as chewing. There are generally no cusps on the teeth, but the rare condition known as talon cusps are most prevalent on the maxillary lateral incisors. 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) maxillary lateral incisor and that of the permanent maxillary lateral incisor. The maxillary lateral incisors occlude in opposition to the mandibular lateral incisors.
Notation
In the universal system of notation, the deciduous maxillary lateral incisors are designated by a letter written in uppercase. The right deciduous maxillary lateral incisor is known as "D", and the left one is known as "G". The international notation has a different system of notation. Thus, the right deciduous maxillary lateral incisor known as "52", and the left one is known as "62".
“Maxillary lateral incisor” enters the record as the second upper tooth from the dental midline on both sides of the mouth. Crown Archives preserves that source wording while asking what Maxillary, lateral and incisor can confirm, complicate or overturn.
Why this record matters
“Maxillary lateral incisor” is worth following because a concise public description often conceals a longer documentary argument. Here, Maxillary, lateral and incisor provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 25, 2025. The linked authority identifier is Q2521804. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
