The aim of root canal therapy (RCT) is to save a tooth that has been damaged due to decay, disease or injury. Many teeth are saved from extraction by having root canal treatment.
Root canal treatment is successful in most cases. Teeth that have been root treated do become weaker than a natural tooth and in majority of cases the tooth will require a crown. If the treated tooth is crowned and taken good care of, it may last for many years and possibly for the rest of your life.
