The term "root canal" is used to identify the natural cavity inside the tooth where the soft area called pulp or pup chamber is found. The nerves of the tooth whose function is sensory can also be found inside the root canal.
If the pulp gets injured (repeated dental procedures, fillings, cracked or broken tooth) or infected (due to tooth decay), the pulp tissues and nerves die which could lead to severe infection when bacteria starts to multiply and therefore has to be removed.
If gone untreated, the surrounding tissues might also get infected which will result in the following: tooth abscess, bone loss around the tip of the root, swelling might spread to the face, neck, or head, and occurrence of hole at the side of the teeth which might cause drainage problem into the gums, cheek, or skin.
However, unlike in the old days when a tooth had to be removed when it became infected, there is a special procedure nowadays called root canal or endodontic treatment where a tooth can be saved from extraction.

Root canal therapy involves repairing and saving the badly infected tooth by removing the pulp and nerves and then protecting it by cleaning and sealing the inside of the tooth. A crown is then placed over the treated tooth to make it stronger.
Saving a natural tooth includes many advantages such as not having to wear artificial tooth/teeth, efficient chewing, prevents jaw problems, and protects other teeth from too much wear and strain.
The branch of dentistry that deals specifically with diseases of the tooth's pulp and the surrounding tissues is called Endodontics.
Root canal treatment can be done by general dentists, but if the issue gets complicated or is being done a second time, patients are often referred to an endodontist. Endodontists are dentists that have gone through specialized studies and trainings that deal solely with root canal treatments.
