Incisive nerve

Last revised by Dr Henry Knipe on 02 Oct 2020

The incisive nerve is one of the two terminal branches of the inferior alveolar nerve, a branch of the posterior division of the mandibular division of the trigeminal nerve. It continues running anteriorly in the mandibular incisive canal (a continuation of the mandibular canal) after the mental nerve branches off to exit via the mental foramen. It supplies the mandibular canine and incisor teeth and their buccal gingiva.
