Sometimes when a patient has a failed root canal below an existing crown the crown can be removed but not always. Removing the crown may damage the existing dental structure – therefore it is often necessary for the dentist/endodontist to drill a hole through an existing neighboring tooth and perform the root canal through this hole. The hole is then filled or concealed by placing a core or white filling over the hole.
If you have a crown with a root canal underneath that has failed then it is always best to see the dentist as soon as possible. If the procedure is too complicated and requires an acipoectomy then Dr. Normatov will refer you to the endodontist.
