🚫 3. Dehydration or Dry Mouth
Not drinking enough water or having a persistently dry mouth (often caused by medications) can reduce saliva flow, which leads to a white coating on your tongue.
Solution: Stay hydrated and consider using sugar-free chewing gum to stimulate saliva.
🧬 4. Leukoplakia
This condition causes white patches on the tongue or inside the mouth and is often linked to irritation from tobacco use or alcohol. While it’s usually harmless, it can sometimes be a precursor to oral cancer.
If the white patches are thick, don’t go away, or are accompanied by pain, it’s wise to see a doctor or dentist.
🔄 5. Lichen Planus
Lichen planus is an autoimmune disorder that causes a lacy white pattern on the tongue and inside the cheeks. It’s typically not serious, but in rare cases, it can cause discomfort or sensitivity.
🍔 6. Diet & Digestion Issues
A white tongue may also indicate digestive problems such as constipation, bloating, or an unbalanced gut. Traditional medicine systems like Ayurveda often associate a coated tongue with poor digestion or the buildup of toxins.
