Mandibular incisors are the front teeth located in the lower jaw, or mandible. There are four mandibular incisors, two on each side, and they are categorized as central and lateral incisors. These teeth are primarily used for cutting and shearing food due to their sharp edges. The shape of mandibular incisors is typically flat and narrow, with a single root. They play a crucial role in proper alignment and function of the bite, as well as in speech and aesthetics. Proper care of these teeth is essential for overall dental health.
