IPA: /ɪˈdɛn.tʃə.ləs/
KK: /ɪˈdɛntjələs/
Describing a person or animal that has no teeth.
The edentulous patient required special dental care.
Edentulous is formed from "e-" (meaning out of or without) and "dentulus" (from Latin "dens", meaning tooth). The word describes a condition of being without teeth.
Think of being 'without' ('e-') 'teeth' ('dentulus') — that's why edentulous means lacking teeth.
