I have a wisdom tooth which is trying to emerge from the gums since the last few years (I'm not sure of the time period). And every time i feel some pain in that region of my gums, i observe that the teeth has progressed in making it's presence felt. The lower jaw does not have any wisdom teeth as of yet. I guess, they'll take their own time to emerge, in the next decade or so.
Speaking of wisdom, gaining it is a not-so-easy, life-long process.
