The superior alveolar arteries are two or three arteries supplying the upper teeth and related structures:

• The posterior superior alveolar artery, a branch of the maxillary artery that serves the upper teeth and other related structures
• The anterior superior alveolar artery, a branch of the infraorbital artery, also supplying the upper teeth and related structures
• The middle superior alveolar artery, an inconstant branch of the infraorbital artery that forms anastomoses with the other two superior alveolar arteries
