Yes as per your query it seems that the cap needs to be replaced and we need to evaluate your case after taking a proper digital x-ray so that we can see that the tooth is not infected again and then after the proper revaluation we can proceed. the process is not painful with the use of latest technology and the cost varies from case to case. for further questions and appointments you can contact us and you can also book an appointment with us online on Practo.
