Root canals can be very succesful and allow people to keep their tooth for decades longer than they otherwise would. But I often do recommend getting an implant instead if it’s an option for my patients financially. Your experience with the extraction isn’t uncommon, root canaled teeth often fuse to the bone and become a nightmare for both the patient and the dentist to remove. It depends on the tooth and the situation though. Definitely best to have a discussion with your doctor to weigh the options in each particular case.
