I feel your anxiety. I'm in the middle of dental **** - have had a sinus lift, 2 inplants, 1 new bridge in progress, 4 replacement crowns, 3 new root canals & 1 revision, 2 implant crowns, 3 teeth gum cutting away, 6 tooth veniers. Now my dentist is working up to placing all in my mouth @ the same time, which will not only change my look but also adjust my overbite a bit. She is a perfectionist which makes me happy. I have learned that sting of the shot is not great but it only lasts about 15-30 secons but the rewards are worth it to me.
I don't know how anyone could get a root canal without some kind of drug. They are messing with a big root. or two. The shot make nerves initially angry but then they all go to lala land.
I usually have tears in my eyes, but after a few seconds, I can relax for the next 2 hours.
I'm sorry for you. Dental work is so modern but scary. A good dentist is an artist. I wish you luck
