I've had one and I am straight up terrified of needles in general. The only thing that hurt me was the initial needle. I won't lie, getting a shot in the roof of the mouth is not a good time, but literally everywhere else is on par, if not less than a regular needle. I don't know how to explain it, but it's less resistance, and a good dentist will numb along the way. Also, let your dentist know. You're not the only one who finds it scary. They'll do what they can to make it comfortable. And if it's long, they usually let you wear headphones. It's not a spa by any means, but once you get the injection (which I promise is not bad), that's it. Hard parts done. And you'll sleep great that night because it'll be all over. 👌🏾
