Don't be afraid
I have had all 4 surgically removed under narcosis (I dont know if thats how you write it, im dutch). And everything went fine, afterwards took painkillers.
The only side effect was that food gets stuck more easily behind back teeth + I developed calculus/teeth stone for some reason. Before that I never had it... So that was quite strange.
But if they need to get pulled, then they need to get pulled
I just read you already did it today, hehe. Well, mine was more drastic: all 4 at once and they had to drill in my cheek bone and stuff. So it took quite a while before it was healed and my cheeks were like a hamster
