Geographic tongue: One explanation could be canker sores but what I think you are describing is what we call geographic tongue. The patches on the surface of the tongue are missing papillae and appear as smooth, red continents hence the name. No one knows the cause but its nothing to worry about. No preventative measures or specific treatments are known to help resolve them.
