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 premolar The premolars, also called premolar teeth, or bicuspids, are transition ...

, and posterior superior alveolar nerve, and an

inferior alveolar nerve The inferior alveolar nerve (IAN) (also the inferior dental nerve) is a branch of the mandibular nerve, which is itself the third branch of the trigeminal nerve. The inferior alveolar nerves supply sensation to the lower teeth. Structure The inf ...

. The superior alveolar nerves are all branches of the

maxillary nerve In neuroanatomy, the maxillary nerve (V) is one of the three branches or divisions of the trigeminal nerve, the fifth (CN V) cranial nerve. It comprises the principal functions of sensation from the maxilla, nasal cavity, sinuses, the palate ...

, 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 ...

, which is the third branch of the

trigeminal nerve In neuroanatomy, the trigeminal nerve (literal translation, lit. ''triplet'' nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for Sense, sensation in the face and motor functions ...
