This cross-sectional type of descriptive study was carried out to isolates, characterization and control of bacteria from failed root canal treatment. The sample size was 101 which was selected purposively. Partially structured questionnaire was used to collect data from the respondents by face to face interview. All efforts were made to collect data accurately. For open questions, the respondents were asked in such a manner way so that they could speak freely and explain their opinion in a normal and neutral way. In total 101 patients 72 were male and 29 were female and the age group between 11-70 years. The first resistance antibiotic is Cephradine and second resistance Cefuroxime. The first sensitive antibiotic is Amoxyclav and second sensitive Cefuroxime. Total 101 patient Streptococcus spp. found Male 43, Female 54 Staphylococcus spp. Male 23, Female 8 and Enterococcus spp. Male 6, Female 10. The most commonly found bacteria is Streptococcus spp. So this study would help the physician to select the proper antibiotics for RCT and make a new era to control the failure of RCT.
