The aim of Endodontic treatment (also known as Root Canal Treatment) is to save a tooth from extraction that has been damaged by decay, disease or injury. It is preferable to save a natural tooth because generally it will function better than an artificial tooth.
If you have a tooth that is causing you pain, it is possible that you may require root canal treatment. If the tooth is damaged or cracked, you have tooth decay, large fillings or have recently suffered trauma to the tooth, the chance of infection and decay increases.
