A member asked:
Does postnasal drip cause a white tongue?
A doctor has provided 1 answer
Not usually: The nasal mucosa produces about a quart of mucus daily. It goes down the throat and we swallow it. I doubt this PND would cause discoloration of the tongue. You need to rule out a fungal infection. See Dentist or ENT doctor.
