Sedation is not very common where I'm from and I've already had wisdom teeth pulled out. It's bizarre but it doesn't hurt at all. Maybe your lips if they're chapped. What you'll feel is the doctor's hand pressing on your face (because leverage) and small cracking noises inside your jaw.

You're gonna be fine, just be sure to take some juice to drink after the extraction. The adrenaline rush is pretty intense. I remember I tried to stand up immediately after I had the first one pulled and my dentist forced me to sit again because I was too wobbly.
