On extreme cases of tooth decay, dentists hardly recommend the complete extraction of a tooth in order to avoid future problems like the weakening of the gums, a decay of neighboring teeth and unshaped jaw. The common solution offered instead is a Root Canal.

What Is A Root Canal?

A root canal is a specialized treatment of decayed tooth performed by an endodontic specialist. To understand further you must know that a tooth has three parts: enamel (crown area), dentin and pulp. The pulp of a tooth consists of the nerve endings, tissues and blood vessels. The endodontic study is the dental science that specializes in understanding and treating the pulp of a tooth. Usually, when there is an inflammation or infection in the tooth, it affects the pulp area. This is because the cavity or decay in a tooth makes way for the germs to directly attack the pulp. Thus a severe pain is caused. Root canal treatment basically saves a tooth by removing the infected pulp and repairing the tooth.

Root Canal: A Step By Step Guide

Given below is the step by step procedure followed in a root canal

Step 1: Local Anaesthesia

Local Anaesthesia is numbing the area around the infected teeth and some part of the neighboring area completely. This ensures that a patient feels no pain during the entire dental procedure of root canal treatment.

Step 2: Shielding And Isolation


The infected tooth is shielded from the rest of the teeth using a sterilized shield held in place by a frame. This is done to isolate the infected tooth from the rest of the oral cavity.

Step 3: Drilling The Crown

An endodontic file is used to drill the crown in order to make way to the pulp of the infected tooth. Sometimes in the case of a very severe tooth decay, the crown is completely removed to reach the pulp. The crown replacement is done after the root canal treatment.

Step 4: Disinfecting the Canal Formed

After drilling the tooth, the canal formed is disinfected in order to kill the existing germs. This ensures that the full canal remains germ-free after the next step or pulp removal is performed.

Step 5: Removal of Infected Pulp

The infected pulp is removed thereafter. This is done using an endodontic plugger. The plugger helps reach the difficult parts of the canal and ensures complete removal of the inflamed or infected pulp. After the pulp is removed, complete cleaning is done once again.

Step 6: Filling The Pulp Area

Post the removal of pulp, a permanent filling is surgically inserted in its place. This filling is done with a material known as gutta percha. Thus it keeps the teeth protected from any further damage or contamination.

Step 7: Restructuring The Crown

After the root canal treatment is complete, the drilling in the tooth is initially covered with a temporary filling. Later it is replaced with a proper crown thus restructuring the entire tooth.
