Root Canal Treatment (RCT) is a dental procedure that can save a severely damaged or infected tooth from extraction. It involves removing the infected pulp and nerves inside the tooth, cleaning and disinfecting the inner chambers, and sealing the tooth to prevent further infection. In this comprehensive guide, we will walk you through the step-by-step process of a root canal procedure.

Step 1: Diagnosis

The first step in a root canal procedure is diagnosing the need for one. Your dentist will review your symptoms, take X-rays, and conduct tests to determine if the pulp inside your tooth is infected or damaged. If necessary, they will recommend a root canal.

Step 2: Local Anesthesia

Before the procedure begins, your dentist will administer a local anesthetic to numb the affected tooth and the surrounding area. This ensures that you remain comfortable and pain-free during the entire process.

Step 3: Isolation

To keep the tooth dry and free from saliva, a rubber dam is placed around it. This isolation technique prevents contamination of the tooth during the procedure.

Step 4: Access Opening

Once the tooth is isolated, your dentist will create an access opening in the crown, usually on the top surface. This access allows them to reach the pulp chamber and root canals.

Step 5: Removal of Infected Tissue

With access to the pulp chamber, your dentist will carefully remove the infected or damaged pulp tissue using specialized instruments. The root canals are also cleaned and shaped to remove any remaining infected material.

Step 6: Cleaning and Disinfection

After the infected tissue is removed, the inner chambers of the tooth are thoroughly cleaned and disinfected. This ensures that no bacteria or debris remain that could cause reinfection.

Step 7: Filling the Canals

Once the tooth is cleaned and disinfected, the empty root canals are filled with a biocompatible material called gutta-percha. This material seals off the canals to prevent further infection.

Step 8: Sealing the Access Opening

After the dental filling of root canals, the access opening in the crown is sealed with a temporary or permanent filling material. In some cases, a crown may be recommended to provide additional support to the tooth.

Step 9: Final Restoration

In the final step, your dentist will discuss options for the restoration of the tooth, such as a dental crown, to protect and strengthen it. A crown is often recommended for teeth that have undergone a root canal procedure.


Root Canal Treatment is a highly successful dental procedure that can save a tooth from extraction and alleviate pain caused by infection or damage. By following these step-by-step guidelines, you can better understand what to expect during a root canal procedure and how it can help preserve your oral health. If you suspect you may need a root canal, consult with your dentist to discuss your options and ensure the best possible outcome for your dental health.
