i read your problem .i need to know about your oral habits
these white spots
can be white precancerous lesions
but these are mostly found in smokers
malnutritous or these can be simple ulcers will heal
itself in 5-6days.
i would advice you keep a check on it for a week if
it remains same consult an oral pathologist and get
a biopsy done.
have high nutritous diet,maintain good oral hygiene
avoid hot and spicy food.
