If a crown comes out can it be recemented?

The answer to this question is it depends. When a patient comes to my office with a crown that has come loose, I inspect the tooth and the inside of the crown. I check for tooth decay and to see if the tooth holding the crown has fractured.

Often crowns that come off should not be reused, since the fit of the crown may have been lacking or the tooth structure holding it has decayed. In that case I will recommend fabricating a new crown for a patient.

If it looks it is a possibility that a crown may be reused, I place it in a ultrasonic cleaner to clean it . After it is cleaned I might try an place it back on the patients tooth and take a bitewing and periapical radiograph in order to check how well the crown covers the tooth.

If the radiographs do not show any problems with the fit or coverage, then If the crown looks like it may still be serviceable I sometimes will recemnent it with a permanent cement.
