Hello. Congrats on getting your braces removed. If you have a good dentist you shouldn't feel a thing while having your wisdom teeth removed. My dentist put me completely out and yours probably will too. In this day and age there is no reason to feel any pain during teeth extractions.
I am probably a lot older than you and I have dentures. I had 18 teeth removed and all of my wisdom teeth removed at the same time. Didn't feel a thing! When I woke up I was still waiting for them to be removed and come to find out my dentures were already in my mouth.
See my pretty smile now
