Through the years, I've had every possible dental procedure done (except for implants--no thanks). Sometimes, a root canal doesn't work; sometimes an apioectomy might work after a failed root canal. But I got to the point where I'd only tolerate so much (after having issues with multiple teeth over time), and I'd request to have a tooth pulled--and I'd be put out of my misery. Had no problem with bridges or partials after the fact. Everyone, and every tooth, is different and some procedures are successful and some aren't. It also depends upon how much money you want to part with, as all these procedures cost a lot. And for the record, I went to all board-certified dentists, endodentists and oral surgeons. My dental insurance would only pay for qualified physicians. (Of course, the dental insurance only paid a pittance of the full bill though!) I hope things turn out well for you, and sorry to hear about your tooth pain.
