Before introducing the term denture, it is important to know the meaning of term prosthesis. Prosthesis is defined as an artificial extension that replaces a missing body part. Loss of natural teeth that is Edentulism can occur due to many causes-periodontal diseases, caries, trauma, hereditary diseases. It can be complete if all the teeth in an arch are missing or partial if some of the teeth are missing in an arch. Prosthetic devices which are used to treat edentulism are called dentures.

Dentures, or false teeth, are fixed or removable replacements for teeth that can be full or partial depending on your needs. Tooth replacement becomes necessary when the tooth and its roots have been irreparably damaged, and the tooth has been lost or must be removed.
