Root canal treatment can last for lifetime, but in case of any recurrent infection and procedural errors endodontic retreatment can save a tooth. Whenever possible it is best to save a natural tooth. In some cases even when treatment has followed the highest standards it still results in endodontic failure. Endodontic failure results from persistent or secondary intra-radicular infection. Extra-radicular infections may be implicated in the failure of some cases. The reason many teeth do not respond to root canal treatment is because of procedural errors. The purpose of this article is to discuss about etiological factors of endodontic failure, removal of gutta percha from canals and different techniques of endodontic retreatment.
