1. A Deep Infection
Root canal treatment is needed when an injury or a large cavity damages the
tooth's root. The root becomes infected or inflamed. |
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.
