gum ridge

[Konrador]

a ridge that forms the borders of the upper and lower jaws and contains the sockets of the teeth

[Mendocky]

A gum ridge refers to the raised line or area of flesh in the mouth where the teeth are or were previously located. There are two gum ridges, one in the upper jaw (maxillary ridge) and one in the lower jaw (mandibular ridge). These ridges become anatomy of interest, especially in dental procedures such as denture fitting.
