White tongue is usually a sign of yeast. Has your LLMD given you any anti-yeast medication? There's a natural medicine (botanical) that my wife took for yeast and it cleared it up in a week.
This is what she used http://abc.eznettools.net/jernigannutraceuticals/yeast-ease.html
This was the only product in many years of suffering with yeast issues that finally took care of it.
If you don't care to use natural medicine for this, tell your LLMD what's going on and he/she will prescribe you some Nystatin or Diflucan.
Take tons of probiotics in the morning when you first get up and before you go to bed. Some people
open a probiotic capsule and put it in their mouth and brush with tooth brush to get the flora back in your mouth.
Hope these ideas help.
