Which dental specialty is responsible for replacing natural teeth with artificial ones or dentures?

Prosthodontics is the dental specialty focused specifically on the design, creation, and fitting of artificial teeth and dentures. This field addresses the restoration and replacement of missing teeth, helping to improve both function and aesthetics for patients who have lost teeth due to factors like decay, injury, or other dental issues. Prosthodontists are trained to work with various prosthetic devices, including crowns, bridges, dentures, and implants, to restore a patient's oral function and appearance.

In contrast, periodontics deals with the treatment of gum disease and the supporting structures of teeth; endodontics focuses on the dental pulp and root canal procedures; and orthodontics specializes in the alignment of teeth and jaws using braces or other devices. Each of these specialties has a distinct focus that does not include the replacement of teeth with artificial ones, which firmly establishes prosthodontics as the correct answer for this question.
