There are yellow/white spots or granules on inside of cheek (Album in post) fordyce granules?

[zano56]

Hey,

I have little yellow/white spots on the inside of my cheek near the back teeth, and they have spread a little to the middle of the cheek over the past few weeks. I went to the dentist first and he said they may be fordyce granules. It doesn't hurt and I can feel individual spots with my tongue. It's not rough, but pops out a little. I have been smoking but only recently tobacco and sporadically, so a few pack in total. I don't think my dentist asked though. I have some pictures here too. What do you think it is? is it serious.

Your dentist is correct: Fordyce granules, or sebaceous glands, totally normal. Nothing to do with smoking, although you should give it up for other reasons!
