The posterior superior alveolar nerves (also posterior superior dental nerves or posterior superior alveolar branches[citation needed]) are sensory branches of the maxillary nerve (CN V2). They arise within the pterygopalatine fossa as a single trunk. They run on or in the maxilla. They provide sensory innervation to the upper molar teeth and adjacent gum, and the maxillary sinus.
