The superior alveolar artery branches off the maxillary artery in the pterygopalatine fossa. It descends to the maxilla where it gives off branches that supply the molar and premolar teeth, the maxillary sinus, and the gingivae. The superior alveolar artery divides into the posterior superior alveolar artery and the anterior superior alveolar artery.
