What area does the long buccal nerve primarily supply?

The long buccal nerve primarily supplies the buccal gingiva of the lower teeth. This nerve is a branch of the mandibular division of the trigeminal nerve (cranial nerve V3) and is specifically responsible for the sensory innervation of the tissue that covers the buccal area, particularly around the molars and premolars in the lower jaw.

This role is essential during dental procedures, as it helps provide the necessary information regarding sensation in that area, allowing dental professionals to assess and manage patient comfort effectively. The long buccal nerve does not supply the chin, upper molars, or upper lip areas, which are innervated by different nerves.
