A dark tongue can be caused by several factors, including medications, drinks, or an accumulation of dead skin cells. While concerning, it's usually not serious.
Here's a more detailed look at the possible reasons:
Potential Causes of a Dark Tongue
- Medications: Certain medications can cause the tongue to darken as a side effect.
- Drinks: Dark-colored drinks like coffee or tea can temporarily stain the tongue.
- Dead Skin Cells: An overgrowth of dead skin cells on the tongue's surface can lead to a dark, sometimes even black, appearance. According to the provided information, this can also make the tongue appear "hairy".
What to Look For
Besides the dark color, you might also notice:
- A "hairy" appearance to your tongue.
- Changes in taste.
- Bad breath.
When to See a Doctor
While a dark tongue is typically harmless, it's always best to consult a doctor or dentist if:
- The discoloration persists for more than a few weeks.
- You experience pain or discomfort.
- You have other unusual symptoms.
