Dental Health :: Painless Raised Dots On Upper Mouth Corner?

I'm a 20 year old smoker who does an awful job at brushing her teeth. I've gone months due to my depression without taking care of my mouth but started brushing everyday since I've found these raised tiny dots on the upper corners of the mouth. they're a pale yellow and they're the size of a pen point, maybe even smaller. I also have a patch on both sides of the inside of my cheeks which recently spread to the corner of my bottom lip on the left side. they don't hurt at all, they don't ooze nor do they bleed or scab. I can't pop them either. when I first discovered them they would sometimes expand about a size or two, turn white and then painlessly pop. this has only happened the first four days they first appeared. it's been two weeks and if anything they have just spread. sometimes they even feel raised and a bit rough when I push my tongue to them then later in the day it will feel like nothing is there or back to their normal size.  I was told these were fordyce spots but I am unsure due to their behavior. I know this isn't contagious because I made out with my partner when these first appeared and he's still fine. I also have a small clear sack on the inside of my cheek on both sides near my bottom teeth.  can anyone confirm that these are fordyce spots? if they are what would you recommend. if not what could these little pests be?
