Why does your tongue change color?

Your tongue can change color for a variety of reasons, some of which are harmless and some of which may indicate an underlying medical condition. Here are some of the most common causes of tongue discoloration:

* Dehydration: When you are dehydrated, your tongue can become dry and red.

* Smoking: Smoking can cause the tongue to become stained yellow or brown.

* Certain foods and drinks: Some foods and drinks, such as coffee, tea, and red wine, can temporarily stain the tongue.

* Medications: Certain medications, such as antibiotics, can cause the tongue to become black or hairy.

* Oral hygiene: Poor oral hygiene can allow bacteria and fungi to build up on the tongue, causing it to become white or coated.

* Medical conditions: Certain medical conditions, such as anemia, diabetes, and vitamin deficiencies, can cause the tongue to change color.

If you are concerned about the color of your tongue, it is important to see a doctor to rule out any underlying medical conditions.
