I had all 4 wisdom teeth cut out at once. (They weren't showing above the gum yet; they were coming in so crooked that if we didn't cut them out when we did, they would have pushed on my other teeth and I would have had to have braces again!) They put me all the way under, and the only side effect from the anesthesia was double vision for about 10 minutes after I woke up.
I don't know what kind of pain killer they gave me, but I had to take an anti-nasea pill 10 minutes before taking the pain killer! The only side effect I had was drowsiness, I slept a lot for the 5 days I took the pills! (Fortunately I was out of school for the summer!)
Since my teeth were cut out, my cheeks swelled up so I looked like a bulldog! (Meanwhile, my brother had his teeth pulled after they had started breaking through the gums, so he didn't swell much or experience as much pain!). I couldn't eat solid food for about 5 days because it hurt .... I lived off of instant mashed potatoes, soup, and chocolate pudding! (One day my mom made me warm chocolate pudding for breakfast, yummy!) I couldn't eat ice cream though because my teeth were also cold sensitive for a while! I also couldn't drink out of a straw because the suction pulled on the stitches.
The stiches they gave me were the kind that starts dissolving after about 10 days ... so for a few days I would suddenly have a piece of stiches come loose and start floating around in my mouth, yuck!
But that means I didn't have to go in for a second appointment to get the stitches out.
