What Happens During a Root Canal Procedure?

Last Updated on March 12, 2024 by admin

 Often feared and misunderstood, a root canal procedure is just one of many dental treatments. When patients hear the phrase, they most likely associate it with pain and discomfort.

Still, a root canal procedure is a highly effective way to save a tooth from damage and infection. In this article, we will take a closer look at what happens during a root canal procedure, debunk some common misconceptions, and highlight the benefits of this dental treatment.

Understanding the need for a root canal

Before diving into the procedure, it’s essential to understand why and when it is needed. It becomes necessary when the soft tissue inside the tooth–the pulp–becomes infected or severely damaged. This issue can occur due to deep decay, a cracked tooth, repeated dental procedures, or trauma. If left untreated, the patient can experience severe pain, sensitivity, swelling, and even abscess formation in the infected area.

After a root canal procedure, the infected pulp is removed, the tooth is cleaned, and the canals are sealed, eliminating the infection and preserving the natural tooth. This treatment not only alleviates the pain but also helps maintain the tooth’s functionality, prevents further damage to neighboring teeth, and eliminates the need for tooth extraction.

Therefore, a root canal procedure saves the tooth and brings significant long-term benefits for oral health and overall well-being. It can restore proper chewing and biting, ensure a more natural appearance, and promote general dental health. Additionally, by preserving the natural tooth structure, a root canal helps maintain the alignment of neighboring teeth and keeps the jawbone healthy.

Step 1: Consultation and diagnosis

First, set up an initial consultation with a dentist. They will examine the affected tooth and determine the extent of the damage. From there, they will decide on the need for a root canal procedure. This initial examination helps the dentist create an appropriate treatment plan, including the required visits.

Step 2: Local anesthesia and isolation

On the day of the treatment, the dentist will apply a local anesthesia application to ensure that the patient is comfortable and pain-free throughout the procedure. Once the anesthesia has taken effect, the dentist will isolate it and keep it dry during treatment. They will use a dam that prevents saliva or bacteria from entering the tooth.

Step 3: Accessing the pulp chamber

After the isolation, the dentist makes a small access hole on the tooth surface, typically at the back of the tooth or on the top. This access point allows the dentist to reach the tooth’s pulp chamber and root canals.

Step 4: Cleaning and shaping the root canals

With access to the pulp chamber, the dentist uses specialized tools to remove the infected pulp tissue and any decayed matter carefully. The root canals are then cleaned thoroughly to eliminate any bacteria or debris. The dentist uses disinfectant solutions and irrigation to flush out the root canals to ensure complete cleanliness.

Step 5: Filling the root canals

Once cleaned and shaped, a dentist will fill them with a biocompatible gutta-percha material. This rubbery material seals off the canals, preventing any further infection or damage. By sealing the root canals, the gutta-percha prevents bacteria, saliva, and any other potential contaminants from entering and re-infecting the tooth. It is highly compatible with the body and does not cause any adverse reactions.

Step 6: Restoring the tooth

After the root canal is complete, the access hole on the tooth surface is typically filled with a temporary filling. This temporary filling offers protection until a permanent restoration filling can seal the area. The crown acts as a protective cap for the weak, treated tooth, restoring its function and aesthetics.


Despite its dreaded reputation, a root canal procedure is not something to fear. It is a valuable dental treatment that can save a severely damaged or infected tooth, preventing tooth extraction. Understanding the steps involved in a root canal procedure helps dispel misconceptions.

It allows patients to approach the treatment with more confidence. Remember, early detection and timely treatment are vital in preserving your dental health, so don’t hesitate to consult a dentist if you are experiencing any symptoms that may indicate the need for a root canal.
