Eventhough you have given the details of biopsy
report,clinical examination of the lesion is required to give a final diagnosis.
Chances of the lesion being oral thrush
is very high.
I would advice you to maintain oral hygiene
Use tongue scrapers to clean your tongue.
Rinse your mouth after every meals.
Intake of spicy,salty food items has to be limited.
Please do visit a dentist
for further treatment.
Hope this helps.
