Root canal therapy (or endodontic treatment) may be required if the nerve of the tooth is compromised by decay, cracks, gum disease, wear and tear or an injury to the tooth. Accurate and thorough diagnosis is imperative in determining whether this is the most appropriate and recommended course of treatment and this may involve performing a cold test, taking a radiograph (x-ray) and tapping/biting on the tooth.

The benefit of choosing RCT is to preserve the tooth, avoiding extraction and tooth loss. It involves 3 stages that include removing the pulp/nerve and the medicating the tooth, cleaning/shaping the nerve canals and finally a filling is placed in the roots of the tooth. A restoration or filling that covers and protects the tooth, and in some circumstances a crown is also an important part of the process as these teeth have an increased risk of fracture and adequate reinforcement is essential in preventing tooth loss and fracture.
