Each person is different, but for me I just tolerated the mild discomfort of wisdom teeth when they came in. That was about 30 years ago, and I still have them.
I don't think it's necessary to have the wisdom teeth out, unless there's a good reason. Other people will argue that they should just come out, just to get it over with - so that potential problems won't develop later on. On the otherhand, I've heard that some people have had problems with TMJ after having their wisdom teeth out. I don't know if that can actually happen, but that's just what I've read on this site.
So, in summary I think if "it ain't broke, don't fix it"....just my opinion.
