Some of the other signs of early dehydration beyond just the white tongue are:
• Extreme fatigue
• Lightheadedness

• Dry lips

• Lack of saliva production
Another factor of a white tongue is tobacco use, eating too much sugar, overconsumption of alcohol, not brushing your teeth frequently, etc. A medical condition that is associated with having white patches on your tongue is leukoplakia. And that is often linked to tobacco and alcohol use.
