It is performed when the initial root canal treatment has failed or when signs of infection reappear. Despite being more complex than the first procedure, retreatment has a success rate ranging between <strong>70% and 90%<\/strong>, especially when diagnosed early and applied with the right technique.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Is_Revision_Root_Canal_Treatment_Necessary\"><\/span>Why Is Revision Root Canal Treatment Necessary?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are several reasons why a previously treated tooth may need to be retreated:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Incomplete_Cleaning_of_the_Canals\"><\/span>1. Incomplete Cleaning of the Canals<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the canals were not thoroughly cleaned during the first treatment, residual infected tissue may remain and cause recurrent problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Inadequate_Canal_Filling_or_Leakage\"><\/span>2.
