Considering the advancement of curative and preventive dentistry, edentulism is still a challenging problem for healthcare providers all over the world.

The socioeconomical factors also contribute to the edentulism as it has an association with education and income status. This literature review will put some highlights in the epidemiology and etiology of edentulism, its prevalence, and the association with the social-economical factors.
