“Root canal” is the term used to describe the natural cavity within the centre of the tooth. The pulp or pulp chamber is the soft area within the root canal. The tooth’s nerve lies within the root canal. A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. When the pulp of a tooth is invaded by bacteria or its get damaged by trauma, the highly vascular pulp tissue produces exudate and causes immense pain. Since toothy is an end organ and pulp is closed space often this pain can be severe.
During a root canal procedure the tooth is first anesthetized using local anaesthesia and then the drills are used to enter inside the toothcutting the dentin and enamel. The nerve and infected pulp are then removed , canals are irrigated with different antiseptic fluids,and the inside of the tooth is cleaned and sealed with a bio inert material mainly gutta percha. Before the treatment diagnostic x-rays are taken to evaluate the extent of infection or damage to the pulp.
The root canal treatment can be performed in single visit to multiple visits depending on the severity of the damage to the pulp. Now days with technological advancement the root canal treatment is very accurate and quickly done.
Normally after the root canal treatment tooth pain subsides but occasionally failure may occur due to missed out canal. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.
