Hello mam Root canal treatment is done stage by stage some times dentist might not be able to clean your teeth due to various reasons like excessive infection , curved root , reduced accessibility and other reasons. It doesn't mean he or she is incapable. So during that stage you might experience some tenderness and pain or sensitivity which is normal ..

Hi ! I think your RCT is not yet complete and it is still being performed. The dentist you are going to might have explained to u that RCT is quite a long process and the dressing in your teeth needs to b changed periodically. I think he is doing his job.
