The nerve divides into the posterior, middle, and anteriorsuperior dental branches. The posterior branch supplies themolar teeth, the gums, and adjacent buccal mucosa, while smallerbranches terminate in the canine fossa; the middle branch passesalong the outer wall of the maxillary sinus, supplying the bicus-pid teeth; and the anterior branch, the largest, passes througha canal close to the infra-orbital foramen over the anterior wallof the maxillary sinus, and distributes its filaments to the incisor.

The hard palate, the periosteum, and the palatine gum tissuereceive their innervation from the anterior palatine nerve fromMeckels ganglion, which enters through the posterior palatineforamen and the accessory palatine canals, passing forward in agroove and joining anteriorly with the naso-palatine nerve as itemerges from the anterior palatine foramina of Scarpa.
