I've taken two of my wisdom tooth out
the procedure was painless, but it stings a little bit after the anesthetic went off
to avoid puffing (and infection), ask ur doctor to prescribe some antibiotics, and take them about 3-4 days in advance regularly to avoid infection and inflammation (puffing) ...... I never had puffing in either opeartion....
also my doctor was pretty good, it was only a local anesthesic... I did not feel any pain at all (just felt the grinding of metal to my teeth)
after the teeth is taken out, there will be a hole, my dentist didnt stich up the hole because he said that it will fill up normally (better than stiching, because food can still slip by the stiches).... also my mom told me to take some chinese medicine to fasten up the recovery (I took yunan pai yao), I only did this for the second operation, and the hole filled up reallly quickly
