The tooth is made up of 2 parts: crown and root. The crown is what you see when you open your mouth. The root is below the gum line. The hard outer shell of crown is enamel which protects the underlying structures from getting infected by bacterial invasion.
The root canal is a hollow cavity within the tooth that houses the vital part of the tooth- the pulp. The pulp provides nutrition to the tooth via blood vessels and gives feeling to the tooth via nerves.
The root canal therapy is needed when the nerve of a tooth is affected by decay, infection or trauma. In order to save the tooth, the pulp and the decay is removed and the resulting space is filled with special, medicated dental materials, which restores the tooth to its full function.
Having a root canal on a tooth is the treatment of choice to save a tooth that otherwise would die and have to be removed. Many patients believe that removing a tooth that has problem is the solution, but what is not realized is that pulling out a tooth will ultimately be more costly and cause significant problems for adjacent teeth.
Some indications of the need for RCT:
-An abscess (or pimple) on the gums.
-Sensitivity to hot and cold.
-Swelling and/ or tenderness.
-Spontaneous pain or throbbing while biting.
-discolouration of the tooth.
-Severe pain during sleep.
Length of the treatment:
RCT can be done in one or more visits. It depends upon the situation. An uncomplicated RCT often can be completed in one visit. Once the RCT is finished, a crown or routinely known as cap on it is must to prevent the tooth from breaking in the future.
