ELI5: If our bodies have no use for organs like the appendix or wisdom teeth, why haven't they disappeared by now?

I know that evolving and changing a physical makeup can take hundreds and hundreds of generations, but why do our bodies still grow things that it has no use or space for?

I just got my wisdom teeth removed and it's made me curious.

Evolution takes a really really long time, and since we know how to remove them from people, we've effectively removed the evolutionary pressure to evolve past them.

As long as we continue to let people with wisdom teeth and appendices mate,and remove them when they cause trouble, we're pretty much stuck with them.
