Anatomy

The Mandibular Central Incisor is the smallest tooth in the human mouth. It has a sharp, chisel-shaped crown for cutting food and a single root. The tooth is wider mesiodistally than labiolingually, which is a unique feature among all the incisors.

Development

The development of the Mandibular Central Incisor begins in the fetus at about the 14th week of intrauterine life. The tooth erupts into the mouth at about 6 to 7 months of age. The permanent Mandibular Central Incisor replaces the deciduous, or baby, tooth at about 6 to 7 years of age.

Function

The primary function of the Mandibular Central Incisor is to cut food during mastication, or chewing. It also plays a significant role in speech and facial aesthetics.

Clinical Significance

The Mandibular Central Incisor is often the first tooth to show signs of dental diseases such as dental caries and periodontal disease. Its position and visibility make it a critical tooth in dental restoration and orthodontic treatment.
