What Is Root Canal Treatment?

Root Canal Treatment (RCT) is the dental treatment required to save a tooth. When decay (caries) goes beyond the 2 layers of the tooth, Enamel and Dentine, it reaches the innermost chamber of the tooth- PULP CHAMBER. The pulp chamber contains the blood vessels, nerve tissue and lymphatic tissue. 

When the pulp chamber of the tooth is exposed, the tooth can not be filled by normal fillings. The pulp chamber and the root canal needs to be cleaned and filled in till the apex of the root.

The root canal treatment procedure involves 3 steps (root canal treatment steps)

Step : 1


The patient is given Local Anesthetic. The tooth is drilled into until the chamber is reached. Once the pulp chamber is open, the pulp tissue from the chamber is removed and the openings of the canal are negotiated. An X ray is taken with files inside the canals to determine the length of the roots

Different teeth have different number of roots and canals. The canals are negotiated, cleaned and enlarged to a specific size. Explained in the  root canal treatment video  

Step : 3


The cleaned canals are then filled up with a special filling material called GUTTA PERCHA upto the ends of the roots. The rest of the tooth is then filled up with a permanent filling material to seal the tooth completely.
