What Is Black Hairy Tongue?
6. How Is Black Hairy Tongue Diagnosed?
The primary method of diagnosis is by observing the appearance of the tongue. Since the look of black hairy tongue can be distinctive, it can be easy for a physician to diagnose. Before a diagnosis is made, other conditions may also need to be ruled out. The physician takes note of any medications that could have caused the tongue changes.
The physician makes sure the discoloration is not within the normal color spectrum for a tongue and that the patient hasn’t recently been eating or drinking anything that can cause temporary discoloration. Some infections that are viral or fungal can cause a similar appearance. Some lesions can also be dark and hairy in appearance.
