The alveolar nerves include three superior alveolar nerves: the

anterior superior alveolar nerve The anterior superior alveolar nerve (or anterior superior dental nerve), is a branch of the infraorbital nerve, itself a branch of the maxillary nerve (V2). It branches from the infraorbital nerve within the infraorbital canal before the infraorbi ...

middle superior alveolar nerve The middle superior alveolar nerve is a nerve that drops from the infraorbital portion of the maxillary nerve to supply the sinus mucosa, the roots of the maxillary premolars, and the mesiobuccal root of the first maxillary molar. It is not al ...

, and posterior superior alveolar nerve, and an inferior alveolar nerve. The superior alveolar nerves are all branches of the maxillary nerve, which is the second branch of the trigeminal nerve. The inferior alveolar nerve, which is small in length, is a branch of the

mandibular nerve In neuroanatomy, the mandibular nerve (V) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V). Unlike the other divisions of the trigeminal nerve (ophthalmic nerve, maxillary nerve) which contain only aff ...
