Leukoplakias are lesions that consist of a whitish patch on the mucosa, tongue or other keratinized portions of the mouth in smokers. They need to be differentiated from lesions associated with candidiasis and lichen planas. Unlike the white patches associated with candidiasis, these lesions can not be easily scraped off and consist of overly keratinized tissue. Often they are referred to as 'precancerous' lessions by dentists.
If you have a white patch on your tongue or somewhere else in the mouth, it is best to see your dentist. He may advise biopsy, since a small percentage of these lesions do have dysplastic areas that can be associated with a malignancy.
