Root Canal Treatment
A root canal is a treatment to repair and save a badly damaged or infected tooth. The procedure involves removing the damaged area of the tooth (the pulp), cleaning and disinfecting it and then filling and sealing it. The common causes affecting the pulp are a cracked tooth, a deep cavity, repeated dental treatment to the tooth or trauma. The term "root canal" comes from cleaning of the canals inside the tooth's root.
2. A Route to the Root
The dentist numbs the tooth. An opening is made through the crown of the tooth to the pulp chamber
3. Removing the Infected/Inflamed Tissue
Special files are used to clean the infection and unhealthy pulp out of the canals. Then they shape the canals for the filling material. Irrigation is used to help clean the canals and remove debris.
4. 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.
5. 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.
6. Extra Support
In some cases, a post is placed into the root next to the gutta-percha. This gives the crown more support.
7. The Crowning Touch
The crown is cemented into place.
