Wisdom Teeth Stopped Hurting Completely?

OK, I have this wisdom teeth (upper right corner) that was hurting like never before it's been going on for a week. So the day before yesterday I placed an appointment for my dentist to get rid of the damn thing, but for some reason it stopped hurting it's like it was never there. To test it out I tried drinking cold water but nothing happens, it stopped hurting completely for 2 days now and my appointment is on this upcoming Thursday. So my question is should I still have it remove? or leave the damn thing alone.
