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 normal function. Having a root canal done in a painful 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 a problem is the solution to get rid of pain but what they don’t realize that pulling out a tooth will ultimately jeopardize their dental and Overall health more and replacing the lost tooth in future would definitely be a more time consuming and costlier option.
RCT can be done in one or more visits. It depends upon the situation. Single Visit Root Canals are advisable when time is a constraint and Root canal is not complicated. Once the RCT is finished, a crown or routinely known as a cap on it is a must to prevent the tooth from breaking in the future.
