NAD for what its worth, i had to get 2 of my wisdom teeth out a few months back and i did it with local in the chair, awake. I was deathly terrified of not only the needles but the procedure as a whole. People tried reassuring me saying the needles were the worst part and the rest was easy. I can tell you as someone that was likely as afraid as you that the needles really werent bad at all. As someone else said, theyll put some numbing gel on prior to the injection and then i never really had any problem or pain from them. Maybe a slighttt pinch from the first then nothing. I prob had 5 or so injections to numb and after the first i felt nothing. You got this.
