How do you make a temporary crown?

To make a temporary crown, start by taking an impression of the prepared tooth using dental putty or a silicone material. Once the impression is set, use a dental material like acrylic or composite to create the crown, shaping it to fit the tooth. After it hardens, adjust the crown for proper fit and bite, then temporarily cement it onto the tooth with temporary dental cement. Ensure the patient knows to avoid hard foods until the permanent crown is placed.
