The trigeminal nerve (cranial nerve V) is the primary source of oral cavity innervation. It has three main branches: maxillary, mandibular, and ophthalmic. The maxillary branch supplies sensory innervation to the upper teeth, gums, upper lip, hard palate, and the mucosa of the maxillary sinus. The mandibular branch supplies sensation to the lower teeth, gums, lower lip, cheeks, and tongue.
