Root canals are required when a tooth is grossly decayed and pulp gets infected. The pulp is the soft area within the center of the tooth that is attached to the tooth’s nerves. When damaged, bacteria begin to multiply and lead to infection. Sometimes repeated dental procedures, cracks or chips in the tooth, and trauma can also lead to development of an infected lesion thereby making a root canal treatment a necessity in that condition.

You may need a root canal if:

  • You are experiencing severe toothache pain upon chewing.
  • Prolonged sensitivity to hot or cold temperature.
  • Darkening of the natural tooth.
  • Swelling or tenderness in the nearby gums may also be signs that a root canal is needed.

Root Canal Procedure

1. During the root canal procedure, the damaged tooth pulp/nerve is removed to prevent further problems within the tooth.

2. In the first appointment, a small hole is drilled in the tooth to reach the infected tooth pulp, which is removed with the help of precise instruments.  

3. Suitable medication is placed to kill the bacteria causing infection.

4. Temporary filling is placed in the tooth until the final completion of the RCT.  

5. During the subsequent visit, the temporary filling is removed and the tooth is re-cleaned to remove any remaining infection.  

6. The tooth is then permanently filled with a dental material known as Gutta Percha mixed with suitable dental sealer.

7. The treated tooth is considered dead after this procedure, but the gum tissue surrounding the tooth is still alive. So to prevent further fracture in the tooth, a dental crown placement is recommended.


After the treatment you may or may not feel a little discomfort particularly during eating. You should avoid eating hard or sticky foods for initial few days and eat from the opposite side. You should regularly take pain medication as prescribed to help prevent pain and postoperative swelling.
