What is Root Canal Treatment?
Root canal treatment involves the removal of the nerve or pulp from under the enamel and dentin layers of the tooth, from both the crown and root. After the pulp tissue is removed, the resulting cavity is filled with canal-filling materials. In simple terms, when the pulp tissue of a tooth becomes damaged or infected (such as in the case of an abscess) due to deep decay or trauma, endodontic treatment (root canal treatment) is performed to save the tooth that cannot be restored by a regular filling.
How is Root Canal Treatment Performed?
The tooth undergoing root canal treatment is first numbed with local anesthesia. The area is then isolated to keep it dry and free from saliva. An access hole is drilled into the tooth to reach the root canal, through which the decayed nerve tissue and pulp are removed. The cleaning process is carried out using root canal files.
These files, of increasing diameter, are inserted into the canal to clear the walls of any infected tissue and bacteria. The canals are washed with various antibacterial solutions after each filing to ensure thorough cleaning. Finally, the root canals, now isolated from blood and saliva, are filled with canal-filling materials, ensuring no leaks or gaps remain that could allow bacterial infiltration.
After Root Canal Treatment
Pain in the treated tooth after root canal treatment is normal and temporary. Sensitivity will decrease over time and eventually disappear. However, if you experience increased pain or swelling, you should consult your dentist.
