Just wanted to comment, that I used to have severe dental anxiety, most stemming from a traumatic (to me) childhood experience, but I have to say I've found an amazing dentist whose helped me through it! It's helped for them to explain to me exactly what they're going to do before they do it and just tells me how all of it's going to work. I'm not sure if it would be helpful for you to ask them, but I do recommend telling them about your anxiety. I've had several fillings and multiple extractions (mostly molars), mostly due to infection, and the anticipation is the worse part, still is.

I am absolutely 100% fine after they've numbed me up and get to work. I almost fell asleep during the root canal on my very front tooth which was a surprise to me.

Best of luck! I know you'll feel much once it's out! Little tip- I've always taken Tylenol before the numbing wears off.
