10 Causes of White Tongue
Cause #9: Dehydration and Dry Mouth
When a person does not drink adequate fluids, dehydration can occur. Symptoms of dehydration include decreased urine output, headaches, and pallor. However, it also results in a dry mouth and tongue, which become a breeding ground for bacteria.
