Hello,
From your description and images, this appears to be linea alba—a common, benign frictional line caused by cheek biting, teeth contact, dryness, or mild irritation. The fact that it reduces with Kenocort and during moist conditions and has not progressed for months is reassuring.
Dry mouth, gastric reflux, and past tobacco use can make such lines more noticeable. Since the surface is no longer rough and there is no increase in size, pain, or ulceration, this does not look suspicious at present.
Maintain good hydration, avoid cheek biting, manage gastric issues, and continue tobacco abstinence. If the line thickens, becomes non-scrapable, painful, or starts increasing, then an in-person oral examination is advised.
Hope this helps.
