Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the
white patch on the inner cheek can be due to
Frictional Keratosis in case if you have a habit of cheek bite in which there is excess production of Keratin ad a protective phenomena..
While the other cause of white patches over the cheek and roof of mouth can be due to
Leukoplakia which is a Precancerous lesion..
Burning sensation of tongue seems to be due to Apthous
Stomatitis causing due to inflammation of tongue..
I would suggest you to consult an Oral Physician and get evaluated and a clinical evaluation and if needed biopsy of the white patches can help in diagnosis and treatment can be done accordingly..
As of now you should first of all stop dipping as it is very harmful..
You can start taking Multivitamins, anti oxidants like Lycopene and maintain a good
Oral hygiene..
Gargle with numbing mouthwash to relieve pain in tongue.
Do cold water gargles..
Hope this information helps..
Thanks and regards.
