Obturation (Filling of the Canal System)
After the canal system has been cleaned and shaped ,the canals are dried. A thin layer of cement is applied to the canals and a material known as Gutta Percha (a rubber-like material made from the sap of a tropical tree) is used to seal the canals. A temporary filling is placed to close the opening in the tooth. You are then referred back to your dentist for reconstruction.
In some cases, one of the canals is specially prepared after filling. A space is created in one canal to accommodate a Post. The Post is used to retain a Core Buildup which is sometimes used as a foundation for a crown. |
