Hi avoid spicy, hot food. Apply tan X gum paint four to five times a day with cotton. Go for check up

You might have taken some hot and spicy food. Apply orasol topically and avoid hot and spicy food. If this problem doesnt resolve in one week then consult dentist

It could be a reaction to something you have eaten or some kind of ulceration. Best to see a doctor for proper diagnosis.
