ive had like 4 operations:
1) the doctor had to pull out a sideways tooth, pulled out the wrong one and stuck it back in then pulled out the right one
2) had a root canal for the now dead tooth from op 1
3)had wisdom teeth removed
4) had the tooth from op 1 that fused to the bone cut out with bone and re-inserted into the proper place.

all on top of braces. they werent that painful though, i was out for all except the root canal. people say root canals hurt, i didnt feel a thing, guess thats a good thing.
