Wisdom tooth = wisdom?

I suspect that there is a wisdom tooth growing, but I really don't know. I am just not able to close my mouth fully as the last tooth or gum, or whatever I can't see clearly will be pain. I have had several toothache recently. It's strange because I always have toothache near exam periods. Why? =/

Made an appointment with the polyclinic and it is morning 8.10am at jurong. Feels like as if I have to wake up early to go jj to attend classes. So early =/  And it is an appointment next year, just before chinese new year. =//
