I have 2 mm round white patch at my cheek for last 14 days ,i am smoker but rare when I visit to ent doctor he said its leukoplakia, he advised me antioxidant and clean my teeth to dentist, when I go to dentist he told me that's not like leukoplakia, I am confused who is right. Some time I saw my patch is small some time see it's bigger. Help me with your advise.
