White spot on gums?!

White spot on gums?

I have a small white spot on my gums near my bottom wisdom tooth. My wisdom tooth is impacted and will be removed in a few months. The gum swells up from time to time and hurts but then swelling and pain will subside. I've never noticed a white spot before but then again I haven't really looked for it. The white spot only hurts when there is pressure on it. The white spot is flat and doesn't puss that I have seen. I have tried to feel for a "pimple" of sorts to pop but the white spot is flush with my gum. My gum is swollen around my wisdom tooth causing mild discomfort. If it continues after a few more days I am going to the dentist, but I was curious as to what I can expect to hear... any dentists out there wanna shed some light?

I should add that I had dental Xrays about 2 months ago and they didnt notice any problems.

Dont ask these questions on the internet pls.Go see a dentist.This is the only correct thing to do.
