It hurt. Not in a "oh no, something's gone horribly wrong," hurt, but an "ow, this is normal, but still sucks," hurt. The process took maybe 20 minutes. I spent 15 in the waiting room, 5 in the chair. The doctor plucked my temp crown off, slapped my new one on, said it would hurt for a day or two. "The pain is because it's a tight fit, as it should be. The tissues will adapt, but it will be sore for a little while. Don't eat anything for a few hours." Then I walked home.
I took my last two Alieve, and it helped a little. I tried to eat comfort food, but it was hard to chew, since I only have that one side of the mouth to chew with. I ended up chewing with my tongue and the front parts of my teeth. Tuesday the pain was less, but when I accidentally bit down too hard, my whole jaw hurt. Last night I started to grind my teeth, and I have been unable to sleep very soundly.
I took Tylenol, which either keeps me up too late, or if I take it right before I go to sleep, it makes me groggy as hell in the morning. I am also sleeping on my back wrong, which isn't helping.
I don't know about you, but more than half the time, painkillers make things worse for me.
