Candidiasis: With out being examined it is not possible to say for sure, but candidiasis (a fungal infection) is a very likely culprit. This can be treated by medication prescribed by your dentist or M.D. Frequent candidiasis in an adult can be a sign of immune suppression. Please see your doctor for a valuation asap.

White spots: Any white lesion in the mouth of 2 weeks or greater duration. Especially if you smoke or consume alcohol on a regular basis, demands immediate examination. As we cannot examine you and only have your well meaning but abbreviated description, we cannot diagnose nor can we treat. Please, without delay, make appointment with your Dentist or an Oral Surgeon.
