Stains on my tongue?
I have had black stains on my tongue for the last 4 days. They do not affect my taste or anything other than they are there. Have you any idea what is the cause?

Smoking or fungus. I would brush the tongue
Bismuth contain solutions can discolor tongue. Also mouth breathing. Also fungal infections. Advise brushing tongue with baking soda. If the black spots are scattered could be benign melanosis
