not metallic either?
the white tongue could be Candida.
I did read recently though that a slightly whitish tongue is normal...but if it's really white, and cottage cheese looking - that is definitely a yeast issue.
When I read that, I looked in a mirror, stuck out my tongue...and it is a slight whitish color...very minimal.
Here's what it can look like. These look like extreme cases though...warning - not pretty.

The naturopath says: A thin coating on the tongue is healthy and normal. A heavy white plaque however could indicate candidasis or oral thrush - a fungus infection of warm, moist areas of the body. This could be caused by an over-use of chemical mouthwash or taking too many antibiotics. Oral thrush can impair taste buds and cause bad breath.
To clean the tongue use a natural mouthwash twice a day. Mix cider vinegar with two cloves of garlic, one teaspoon of dried sage and one table spoon of honey poured into one pint of boiling water. Store in the fridge and use within three days.
The Chinese herbalist says: This reflects the state of the digestive sysem. If the tongue lacks coating, it means the stomach enzymes which break down food in the digestive system are not functioning properly. The coating of the tongue should be thin and white.
