Root canal therapy is a dental procedure performed by dentists when the tooth pulp gets infected. This procedure retards the current infection and also protect the contaminated tooth from further infections. Even though this process is quite complicated and may need multiple visits to the dentist, sometimes it is the only viable option to save the tooth.

Beneath and inside the white enamel of the tooth are the hard dentin layer and the soft tissue called pulp from where the tooth root grows. The latter contains blood vessels, nerve tissues, and connective tissues. When this pulp gets infected, a dentist may have to perform root canal treatment or RCT to remove the infected pulp tissue through a process known as pulpectomy. The nerve of the root canal is also drilled out. Dentists widens the canals with the help of files and debris to remove the infected tissues. This allows greater penetration of the irrigating solution, used in subsequent treatment. The uncontaminated canals are filled with an inert filling and then sealed. Ultimately, the dentists fix a a crown to prevent breakage of the tooth.
