What is a removable prosthesis that replaces one or several teeth called?

  1. Crown

  2. Bridge

  3. Partial

  4. Denture

The correct answer is: Partial

A Crown is a prosthetic dentisty that completely covers or caps a tooth or dental implant. It is not used to replace multiple teeth. A Bridge is a dental restoration that replaces one or more missing teeth. It requires the support of adjacent teeth and is not removable. A Partial is a type of removable denture that replaces multiple missing teeth but not all of them. It is often used when natural teeth are still present. A Denture is a removable prosthetic device that replaces all or most of the teeth on one or both of the arches (upper and lower jaw). So while it is a removable prosthesis, it is not specific to replacing only one or several teeth. Overall, a Partial is the most appropriate answer as it specifically refers to a removable prosthesis that replaces several teeth.
