The dentist may numb the tooth if it is painful. An opening is made through the crown of the tooth to the pulp chamber.
Special files are used to clean the infection and unhealthy pulp is removed out of the canals. Then they shape the canals for the filling material. Irrigation is used to help clean the canals and remove debris.
The canals are filled with a permanent inert rubber material called gutta-percha cones. This helps to keep the canals free of infection or contamination & fills the dead space.
A temporary filling material is placed on top of the gutta-percha to seal the opening. The filling remains until the tooth receives a permanent filling or a crown. A crown, sometimes called a cap is placed over the top of the tooth. It looks like a natural tooth.
In some cases, a post is placed into the root next to the gutta-percha. This gives the crown more support.
To prevent the root canal treated tooth from fracture, an artificial hollow dental crown is constructed & cemented over it.
