No, teeth that have undergone a root canal procedure should not have nerves remaining in the treated tooth. The purpose of a root canal is to remove the infected or inflamed pulp, which contains the nerves, from inside the tooth.
What Happens During a Root Canal?
A root canal procedure involves:
- Accessing the Pulp Chamber: The dentist creates an opening in the tooth to reach the pulp chamber and root canals.
- Removing the Pulp: Using specialized instruments, the dentist carefully removes the infected or inflamed pulp tissue, including the nerves, from the root canals.
- Cleaning and Shaping the Canals: The root canals are then cleaned, disinfected, and shaped to prepare them for filling.
- Filling the Canals: The canals are filled with a biocompatible material, typically gutta-percha, to seal them off and prevent future infection.
- Sealing the Tooth: A filling or crown is placed on the tooth to restore its structure and protect it.
Why Root Canals Eliminate Nerves
The primary goal of a root canal is to eliminate the source of pain and infection, which resides within the pulp tissue. Because the nerves are part of the pulp, their removal is essential for a successful root canal.
Feeling After a Root Canal
While the treated tooth should no longer experience pain related to the nerve, it's possible to have some sensitivity or discomfort in the surrounding tissues after the procedure. This is usually temporary and can be managed with over-the-counter pain relievers. The tooth will still have periodontal ligaments attaching it to bone, and they are innervated.
