Root Canal Treatment - Know more about it!

Your tooth consists of two main parts: the crown, which is that part of the tooth above the gum and visible in your mouth; and the root or roots, which is that part of the tooth that lies beneath the gum and is surrounded by bone. Inside each root is a channel that runs the length of the tooth. This channel is the root canal and contains the pulp (nerves, blood vessels, and soft tissue), which is often referred to as the "nerve" of the tooth. The pulp may be irreversibly damaged by bacteria associated with decay, very deep restorations, fractures, trauma, or periodontal disease.

In order to preserve a tooth in which this has occurred, it is necessary to remove the diseased pulp tissue. This procedure is known as endodontic therapy. Since endodontic therapy is concerned with removing only the pulp from the root canal, the root will continue to function normally because the supporting tissues remain intact. It is advisable to remove the injured pulp because it may become infected or act as an irritant to the tissues surrounding the tooth.

Root canal treatment is a procedure by which the exposed or infected nerves are removed from the root of the tooth and then the canal is cleaned and widened with the help of some instruments and the canal then is sealed with some material so as to leave the canal sterile. The tooth after the root canal treatment will remain non vital but it act as functioning unit.

What your dentist do?

Decayed tooth which has involved inner part of the tooth(pulp)
Opening is made by a drilling machine and canals are located
Canals cleaned and widened by special kind of instruments called reamers and files
Canals sealed by gutta percha, root filling material.
Both crown and root are filled

  1. If your tooth is vital, you will need anaesthesia to make painless procedure. If tooth is already dead you don't have to get anaesthesia.
  2. Then your dentist will make a hole through the chewing surface and this hole will be large enough till he reaches the inner part of the tooth ( that is pulp chamber )
  3. Then he locates the canal. 
  4. Cleans and enlarge the canal with a special instrument called reamers and files.
  5. Once done, then your tooth is ready to be filled. Your canal is ready when it becomes dry and painless.
  6. First he fill the root by a material called gutta percha and then he fills the crown portion by filling materials.
  7. Our RCT procedure can not be done in a single visit. It might take 3/4 or even more visits. This will depend upon the cordination of your tooth.
  8. Tooth like grossly damaged might need crown. Because after RCT, the tooth becomes brittle and has high chance of fracture.
  9. The success of RCT varies. If you feel discomfort or pain even after RCT, you should visit the dentist immediately.

Post Treatment Care

Need of RCT

Sometimes you suffer from acute dental pain.I n such case you have to choose either RCT or extraction to releif your pain. Because the tooth will not heal by itself. Without treatment, the infection will spread, bone around the tooth will begin to degenerate, and the tooth may fall-out. Pain usually worsens until one is forced to seek emergency dental attention. Though an extraction is cheaper, the space left behind will require a bridge, which can be more expensive than root canal therapy. usually extraction of the tooth,cause surrounding teeth to shift crookedly, resulting in a bad bite. If you have the choice, it's always best to keep your original teeth.


1. Root canal treatment helps you to save the tooth.
2. In severe type of acute pain,pain subsides immediately after cleaning of the canal.
