A clinical examination is essential for correct diagnosis of your condition. Few common conditions causing white tongue are oral thrush, leucoplakia, lichen planus.Oral thrush is a yeast infection in the mouth caused by a fungus. It causes a burning sensation on the tongue with white plaques .It is common after taking antibiotics, people with weakened immune system. Leukoplakia can develop after chronic tongue irritation commonly associated with drinking and smoking. In oral lichen planus there are white steaks and white patches on the tongue. The exact cause can be determined only after seeing a doctor. Treatment will depend on the cause.
