yeast infections in the mouth do give you a sensation of a dry mouth though usually it's very burning feeling too.
If you were diagnosed as having a fungal infection in the mouth I"m sure they gave you treatment for it. If you are just wondering if perhaps this is the cause of your dry mouth - see your provider for an exam and testing. Diagnosing an oral fungal infection is pretty easy in the office.
