I remember the feeling of my wisdom teeth coming through the gums and it wasn't pleasant. It sort of felt good to rub the gums back there with my fingers, albeit it might have looked strange to someone else. I almost kind of wanted some sort device to "teeth" on.
It made me have new appreciation for what babies go through when their teeth first come in and why they fuss so much. It also made me understand why they like to gum their teething rings so much.
