The mental nerve is a general somatic afferent (sensory) nerve which provides sensation to the anterior aspects of the chin and lower lip as well as the buccal gingivae of the mandibular anterior teeth and the premolars. It is a branch of the posterior trunk of the inferior alveolar nerve, which is itself a branch of the mandibular division of the trigeminal nerve (CN V).
The nerve emerges at the mental foramen, and divides beneath the Triangularis muscle into three branches:
These branches communicate freely with the facial nerve.
