In my opinion, this feels like a normal mucosa. for oral lichen planus, the most common symptom that you would have had is a burning sensation, especially while having spicy food. For oral dryness, firstly look at your water intake, whether you are dehydrated or not. Secondly, do get your
sugar levels tested, whether you have
diabetes or not. If at all it doesn't subside then do feel free to consult any Oral Surgeon nearby or via online consultation. Also do look out for any skin rashes or other abnormalities.
