Hi..you need to visit a dentist as soon as possible get an xray of the tooth and dentist will find out the cause for your pain.

Hello There are different reasons for pain after cap as in high points on the cap , the tooth is not root canal treated etc.So You should visit the dentist  for removal of high  points if any n get-ray done for further examination if pain doesn't subside .you can take tab Dolo 650mg(if u r not allergic to it) after food  for pain but that's just for temporary relief. For further assistance you can call for online consultation Regards Dr.Bhawana Singh

You have to show the x-ray sir. If the tooth can't be saved there are several ways to replace the teeth

See you didn’t mention whether root canal was done on that tooth or not I suggest you get the x-ray done to check the situation, ifthe root canal was not done you might need a root canal and then the same Cap be fixed againFor more information click drlillys.com
