What is Root Canal (RCT)?
Whether the people know what is a root canal or not, what they know is that it is synonymous with pain. The idea that a root canal is the most painful of dental surgeries is a myth. The procedure can save a dying tooth and prevent the need for an artificial tooth.
A 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 the blood and is also responsible for tooth sensitivity because of the presence of the nerves.
If a canal ever gets infected, which generally occurs when tooth cavities destroys the enamel and dentin, the pulp gets exposed to the outer environment. At this stage the patient feels an intense pain that might even radiate to head and ear, sensitivity to hot and cold and discomfort. If left untreated, an infection occurs causing the death of the pulp and also infection of the surrounding bone. The stage is usually associated with the inability of the tooth to withstand chewing forces. Unless still treated, this pain will likely remain and could result in the tooth eventually falling out.
In order to prevent tooth loss, a root canal surgery must be performed. The surgery is designed to clear out diseased material from inside the canal. To perform a root canal surgery, a hole is drilled into the tooth to allow access to the inner pulp. The diseased pulp is completely removed with special instruments, and the cavity is usually filled and capped with specific inert material.
