Inferior dental plexus

The inferior dental plexus is a nerve plexus formed by sensory branches of the inferior alveolar nerve. The plexus issues dental branches and gingival branches; the small dental branches provide sensory innervation to the lower/mandibular teeth.

Note that the lower premolar, canine and incisor teeth as well as their associated gingiva are innervated by the incisive branch of the inferior alveolar nerve (which may or may not form an incisive plexus).
