Re: White tongue
White tongue is generally caused by Candida. Do you have any soreness on your inner cheeks and gums and any white spots.
It is always best to get a proper diagnoses from your Dr or Dentist. Candida in the mouth which can occur on the tongue, gums, or inner cheeks is known as Thrush,
It responds well to a course of NYSTATIN (prescription only) where I live. You can also buy a mouthwash named ELUDRIL or another named CORSODYL which are both very good for this condition.
Hope this helps and Good Luck,
