Hello,
Thank you for sharing the images.
A persistent white patch inside the lips/cheeks with mild burning can be seen in conditions like oral lichen planus, frictional keratosis (cheek/lip biting), or occasionally a fungal infection.
Since it has been persistent, it requires proper evaluation. Most such lesions are benign, but confirmation is important.
Take care.
Next Steps
I would recommend a detailed assessment, including a few specific questions and close image evaluation.
