Nerve: Mental nerve Distribution of the maxillary and mandibular nerves, and the submaxillary ganglion. (Mental nerve visible at bottom right, at chin.) Sensory areas of the head, showing the general distribution of the three divisions of the fifth nerve. (Mental nerve labeled at bottom left, near chin, in yellow.) Latin nervus mentalis Gray's subject #200 897 Innervates chin, lower lip From inferior alveolar nerve
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).
These branches communicate freely with the facial nerve.
The mental nerve can be blocked with local anesthesia, a procedure used in surgery of the chin, lower lip and buccal mucosa from midline to the second premolar. In this technique, local anesthetic is infiltrated in the soft tissue surrounding the mental foramen.
