Why do we get fur on our tongues?

White Furry Tongues... the lesser know tribute act to Super Furry Animals.

Asked by: John Stark, Uxbridge


If you mean the normal roughness of a healthy tongue, this includes taste buds, and many small, sensitive projections that cover the top surface.

If you mean an additional white or grey furry covering then it’s probably a bacterial or fungal infection such as thrush, and you should get it treated. Healthy tongues are not covered in fur!
