Bryanna will sure respond. If it were me, I would never crown a root cannaled tooth, as that tooth is only temporary at best. I also know about needles. The area in the back of the mouth between your jaws, is where the nerve is to deaden. It takes a skilled and gentle dentist to give the injection so it doesn't hurt. I am 1st class chicken. I am 61 years old and just found such a dentist. There is also a little stimulator device, that can be put on or near the area of injection. This wiggles the entire area, and distracts you so you don't feel it. Also a topical should be used before anything. I do wish you all the best. I just went to the dentist today. YEH! no more work to be done..... hope this happens for you soon too. ginnie
