I had all four removed, one at a time every two weeks in the "chair", when I was 16.

One was mildly impacted. I took it to Biology class cause it was kind of neat. Never saw it again...

One of them would come up, disappear below the gums, rise again (never was a full tooth). They are 'residual' teeth as I understand.

So, those of you who never have had wisdom teeth are likely further along in the evolution path!

Excuse me, I have a sudden craving for a banana....
