A surgical procedure that involves removing gum tissue from the mouth.
The dentist recommended a gingivectomy to treat the patient's gum disease.
Gingivectomy is formed from "gingiva" (from Latin, meaning gums) and "-ectomy" (from Greek "ektomē", meaning excision or removal). The word refers to the surgical removal of gum tissue.
Think of 'gingiva' which means gums, and '-ectomy' which means removal. This helps you remember that a gingivectomy is a procedure that removes gum tissue.
