What happen during root canal

Root canal treatment often conjures images of painful dental procedures in the minds of many, but understanding what actually happens can alleviate much of the fear and anxiety surrounding it. This blog aims to demystify the root canal process, explaining each step in detail, to provide a clearer and more accurate picture of what patients can expect.

The Need for a Root Canal:

A root canal treatment in Islamabad is typically required when the pulp inside the tooth becomes infected or inflamed. This can result from deep decay, repeated dental procedures on the tooth, faulty crowns, or a crack or chip in the tooth. Symptoms may include pain, prolonged sensitivity to heat or cold, discoloration of the tooth, and swelling and tenderness in the nearby gums.

Step 1: Diagnosis and X-rays:

The first step is a thorough examination of the affected tooth. Your dentist will take X-rays to assess the extent of the damage and plan the treatment. These X-rays reveal the shape of the root canals and indicate whether the surrounding bone structures are healthy.

Step 2: Local Anesthesia:

To ensure comfort during the procedure, the dentist administers a local anesthetic to numb the tooth and surrounding area. This is a critical step that helps in alleviating pain and discomfort during the treatment.

Step 3: Isolating the Tooth:

Once the area is numb, the dentist places a small protective sheet called a dental dam over the area to isolate the tooth and keep it clean and free of saliva during the procedure.

Step 4: Creating an Access Hole:

The dentist drills an access hole into the tooth to reach the pulp chamber. This hole provides access to the infected or damaged pulp inside the tooth.

Step 5: Removing the Infected Pulp:

Using special tools, the dentist carefully removes the infected or inflamed pulp from the pulp chamber and root canals. These areas are then cleaned and shaped for the filling material. Cleaning involves flushing out debris and bacteria from the canals.

Step 6: Antibacterial and Antiseptic Treatments:

To ensure that all bacteria are eradicated and to prevent further infection, the cleaned canals may be filled with an antibacterial solution, which also aids in reducing inflammation.

Step 7: Filling the Root Canals:

After cleaning and disinfecting, the canals are filled with a biocompatible material called gutta-percha. This rubber-like material is placed with an adhesive cement to ensure complete sealing of the canals. At this point, the root canal is essentially completed.

Step 8: Rebuilding the Tooth:

Since a considerable amount of tooth structure is often removed during a root canal, the tooth needs to be restored to function normally. If the tooth isn't significantly weakened, a simple filling may suffice. However, if a large part of the tooth or filling is missing, a crown may be needed to restore the tooth's shape, size, and strength, and to protect it from breaking in the future.

Step 9: Aftercare:

Post-procedure care is crucial for a successful outcome. This includes managing soreness or discomfort, which is normal and can be alleviated with over-the-counter pain medications. Good oral hygiene practices, such as regular brushing and flossing, are vital. Additionally, you should avoid chewing on the treated tooth until it's fully restored by your dentist.


Understanding what happens during a root canal can help patients approach this common dental procedure with more confidence and less fear. While the process might seem complex and lengthy, modern techniques and equipment have made it a relatively pain-free and highly successful treatment. It's important to follow your dentist's instructions and attend all follow-up appointments to ensure the best possible outcome. If you're experiencing symptoms that might require a root canal, consult with your dentist promptly for an accurate diagnosis and timely treatment.
