1. How long does Root Canal Treatment last?

The entire root canal procedure may take place in one appointment, or at times 2 or 3 sessions depending on the condition of the tooth. Each appointment may last between 30 – 90 minutes. It is a simple procedure with relatively little or no discomfort.

2. How is the procedure of Root Canal Treatment?

Step 1: At the outset, local anesthesia is administered to the tooth which is to be treated.

Step 2: After the tooth and the surrounding areas become numb, the endodontist drills an opening through the crown or the biting surface of the tooth to access the pulp chamber. If it is a front tooth, the endodontist drills an opening from behind the tooth.

Step 3: Using special files the endodontist cleans out the infected, diseased and dead pulp from the canals. The procedure does not cause any pain as the area is numb due to the anesthesia, and the tissue that is removed is dead.

Step 4: Once all the infected and dead tissue is removed, the canals are disinfected using disinfectants.

Step 5: The canals are then shaped with fine instruments so that they can be filled with the root canal fillings known as gutta-percha and sealed. During the process of shaping, irrigation method is used to wash and clean the canals and remove the debris, before inserting the fillings and sealing the tooth.

Step 6: A temporary cover material which acts like a seal is placed above the gutta percha. This covering material is kept in place till a crown or a cap which looks like a normal tooth is fitted atop the treated tooth.

At times, a post is inserted into the canal next to the gutta percha to give the crown more support.

Step 7: Thereafter, the crown is cemented in place so that it never dislodges.

3. What happens after the procedure?

After the treatment, your tooth will be sensitive to biting pressure and may even appear to feel loose. This is because of the sensitivity of nerve-ending in the tissue outside the end of the root, where is cleaned, irrigated, placed a filler and sealer material and a filling.
