Can geographic tongue disappear eventually? or is it constantly there forever?

Comes and goes: The taste buds on our tongues are constantly being replaced. Typically the pattern is random so we never notice it. With geographic tongue (gt) patches of taste buds get replaced at a time. As new ones fill in and different older ones get replaced the pattern shifts. A person with gt may follow the typical pattern sometimes and the gt pattern at other times. It is considered a normal variation.

It's Episodic: The physical signs of geographic tongue tend to come & go over time. However, the condition never goes away completely. There can be extended periods when you don't really see or notice anything, but that doesn't mean it's gone. For the vast majority of people, there really aren't any serious symptoms--the tongue just looks a bit weird. Alcohol, heat, and spicy foods might be a bit uncomfortable.
