A denture is defined as an artificial substitute for missing natural teeth. They are prosthetic devices designed to replace the teeth and surrounding tissues after tooth loss, allowing individuals to restore functionality for chewing as well as to improve aesthetics by filling out facial structures. Dentures can be complete, replacing all teeth in an arch, or partial, when only some teeth are missing. This option accurately represents the function and purpose of dentures in dental care.

The other choices do not pertain to the definition of a denture. For instance, a temporary filling material is used to fill cavities until a permanent solution is applied, and a type of dental x-ray refers to imaging techniques used to diagnose oral conditions. A specific dental tool does not describe dentures, as they are not a single instrument but rather a prosthetic device. Understanding the role of dentures is essential for recognizing their importance in restorative dentistry and patient care.
