Just one data point, but: as a teenager I was told "your wisdom teeth might end up being fine, but most people end up having to get them pulled; it's up to you." I passed.

Fast-forward a decade or so, one of them was, to use the technical term, totally fucked. It was impacted, uncleanable in parts and thus had to be removed, but had gotten so wedged in that it not only pushed my other teeth crooked, but was extremely hard to extract, requiring the dentist to go fetch some other stronger dentist and then they both worked on it and it took way longer than planned to get all the pieces out.

That was lame, but I still have the other three, and now my dentist says the same thing is happening to those (and even I can tell, it is).

So now I am 41 with a busy job and young children, and I have to find time to have three wisdom teeth extracted in a procedure that is now going to be much more difficult than the simple extraction suggested by my dentist 20 years ago.

So, in my case, I wish I did it then.
