Hi there, thanks for asking. There is no picture of your inside the mouth to tell accurately what it may be. However, leukoplakia
is a common problem that is seen frequently in smokers. A dentist
can say better after examination if they are leukoplakia. If they are, they should be treated since there is chance of converting to malignancy. They also could be candidiasis
which happen in the circumstances the bosy system is not strong enough. Smoking
can change the body defense level as well. I wish you a good health.
