Superior alveolar arteries
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
