Cap of a root canal treated tooth came out recently

Q. Cap(Ceramic) of a root canal treated tooth came out recently.Cap is still intact and even the filling is also fine.I have no other problem other than the loose cap but want to fix the same cap.Is it possible here ?If yes, can you please share the expenses to fix the same cap.

A. If there was a cement failure and the tooth was fine than it may be possible to just re-cement. I You would really appreciate if you can come for an evaluation and X-ray to determine the condition of the tooth.
