<human>: I've been noticing a lot of white specks on my tongue lately. What are the causes of white tongue?
<bot>: White spots on your tongue could be caused by various factors, including dehydration, smoking, and certain medications. It is also possible that you may have an oral fungal infection or thrush. If you're experiencing any discomfort while eating or drinking, it's important to see your dentist as soon as possible for an accurate diagnosis.
