Pain due to Infection
Root canal treatment is needed when an injury or a large cavity damages the tooth's root. The root becomes infected or inflamed.
An opening of the tooth
The dentist numbs the tooth. An opening is made through the crown of the tooth to the pulp chamber.
Removing the Infected/Inflamed Tissue
Special files are used to clean the infection and unhealthy pulp out of the canals. Irrigation is used to help clean the canals and remove debris. Then the canals are shaped for the filling material.
Filling the Canals
The canals are filled with a permanent material. Typically this is done with a material known as gutta-percha. This helps to keep the canals free of infection or contamination.
Rebuilding the Tooth
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, looks like a natural tooth. It is placed over the top of the tooth.
Post and core
In some cases, a post is placed into the root next to the gutta-percha. This gives the crown more support.
