Question: I use smokless tobacco or did. I had my last dentist appointment the other day when I noticed wrinkled skin on my inner cheek. He said I had some keratosis. He said nothing looked suspicious and it was common. I asked him about the leathery grooved feeling area and a tiny bump I seem to feel in that area, on my inner cheek. He said it just looked like keratosis and I could have some irritated areas that would stay inflammed if I continued irritating it.
So, I continued dipping for a few weeks and finally just quit yesterday.
The area seems to be improving rapidly in just 24 hours.
As to the bump, Its difficult to locate with my tongue if i'm not irritating my mouth with snuff. Its also smaller than half a grain of rice.
I noticed when I actually looked inside my own mouth today I can see the healing keratosis which looks like light wrinkled grooves and textured. I inspected my whole mouth just to look around and I also saw all kinds of other things in the tissue of my gums and cheeks of what i'm guessing is just the normal ducts, glands, tissue, etc.. I'm refering to both sides of mouth.
I actually noticed where I do feel what seemed to me like a tiny bump in reality looks like its just part of the keratosis. But on the opposite side of my mouth on the other cheek I dont feel any bump or firmness or anything and theres no keratosis but do see a same tiny flesh colored dot in the same exact location. These are at the corners of my mouth a little lower down.
Are there ducts in these areas? I also noticed a line down each inner side of my cheeks so im thinking there is some anotomical location stuff of probably quite a few things on i'm seeing.

Anyway, your thoughts.
Also, once I remove the irritant how long should it take to heal?
My follow up with dentist is in 2 months.

Thanks for the response.
Yes, when not using tobacco the entire area seems to be responding well. I did notice that a few coffees this morning seemed to make the area feel a little rough or acidic (I often avoid some foods as I have acid reflux per 15 years) but upon inspection it is still looking better.
You may be correct. DDS said that leukoplakia and keratosis were similar but actually different, so not sure what he meant. he said mine was a callus type and consistent with "dippers lip"? Whatever that means?
