To help balance out those of you born with less than four wisdom teeth, I had two extras on the top. The second ones were underneath the first, and caused the tops of the first to point partway towards the lip.
So when I was in either my late 20’s or early 30’s, my dentist recommended pulling them as they were not functioning as chewing surfaces. When removing the two, one of the secondary ones also came out. And the net result was I had three wisdom teeth removed, and today still have three.
