What does the patient wear on a prepared tooth while the crown or bridge is being made?

Permanent Crown
Provisional
Orthodontic Retainer
Nothing

The correct answer is: Provisional

A provisional crown is worn on a prepared tooth while waiting for the final crown or bridge to be made. This is a temporary crown that provides protection for the tooth until the permanent restoration is ready. A permanent crown (option A) is the final restoration that is placed on the prepared tooth. An orthodontic retainer (option C) is typically used to maintain the position of teeth after orthodontic treatment and is not related to crown or bridge procedures. Option D is incorrect because leaving the prepared tooth exposed without any protection can lead to sensitivity, damage, or further decay.
