J.B.
I had my 4 wisdom teeth removed this past January. I was lucky that none of them was impacted as this makes more complicated the process of removal and recovery (that's what I hear).
Definitely the day of the procedure I couldn't take care of my 2 kiddos. I was just napping all day and was overall tired. The pain wasn't huge and I didn't have to take prescribed pain killers just over the counter ones.
On the day of the procedure my face was a little bit swollen and I had some bleeding (sorry TMI) while rinsing my mouth. It took a while for the drugs to leave my system so my face felt numb for a little bit too long for my liking (couldn't talk much- perfect for kids though ;-) ).
You may want to prepare your 6 yo before you go and have the teeth removed.
Good luck and easy recovery!
