The dental removal of a nerve is commonly known as a root canal.
A root canal procedure involves removing the infected or damaged pulp (which contains the nerve) from inside a tooth. Here's a more detailed look:
What Happens During a Root Canal?
- Accessing the Pulp: The dentist creates an opening in the top of the tooth to reach the pulp chamber.
- Removing the Nerve: Using specialized instruments, the dentist carefully removes the infected or inflamed pulp and nerve tissue.
- Cleaning and Shaping: The root canal(s) are cleaned, shaped, and disinfected to eliminate any remaining bacteria or debris.
- Filling: The cleaned root canal(s) are filled with a biocompatible material, typically gutta-percha, to seal the space and prevent future infection.
- Sealing: A temporary filling or sealant is placed to close the access opening.
- Restoration: Finally, a permanent restoration, usually a crown, is placed on the tooth to protect it and restore its function. The crown is necessary as the tooth can become brittle after a root canal.
Why is a Root Canal Necessary?
A root canal is necessary when the pulp inside a tooth becomes infected or inflamed. This can be caused by:
- Deep tooth decay
- Repeated dental procedures on a tooth
- A crack or chip in the tooth
- Injury to the tooth, even if there's no visible crack
Symptoms that may indicate a need for a Root Canal:
- Severe tooth pain, especially when chewing or applying pressure
- Prolonged sensitivity to hot or cold temperatures
- Discoloration of the tooth
- Swelling and tenderness in the gums near the affected tooth
- A persistent pimple on the gums
By removing the infected nerve and sealing the tooth, a root canal saves the tooth from extraction and prevents further spread of infection.
