Prosthodontic treatment is a type of dental treatment that involves the restoration or replacement of teeth. This can be done for a variety of reasons, such as to improve the function of the teeth, to improve the aesthetics of the teeth, or to repair damage to the teeth. This can be done through a variety of different methods, including dentures, bridges, implants, and more. 

Prosthodontic treatment can be performed on both adults and children. However, it is most commonly performed on adults, as they are more likely to have missing or damaged teeth.
