What area does the superior dental nerve primarily supply?

The superior dental nerve, which is a branch of the maxillary nerve (V2), primarily innervates the upper teeth, specifically the maxillary molars, premolars, and incisors. In addition to the teeth, it also provides sensory supply to the buccal gingiva, which is the gum tissue located in the upper jaw area that surrounds the upper teeth. This nerve is crucial for dental procedures in the maxillary region since it helps in sensation and pain perception related to both the teeth and the surrounding gum tissues.

Understanding the anatomy and innervation patterns assists dental professionals in effectively managing pain during procedures and ensuring appropriate anesthesia applications, particularly in upper dental work. The other options describe regions innervated by different nerves, such as the mandibular nerve for lower teeth and gingiva or the glossopharyngeal nerve for the tongue, highlighting distinct nerve functions within the oral cavity.
