A tongue that is white, red, black, or yellow is generally considered unhealthy.
Here's a breakdown of what different tongue colors can indicate:
-
White Tongue: A white coating on the tongue is often caused by oral thrush (a yeast infection) or leukoplakia (thickened, white patches that can be caused by irritation). It can also be due to poor oral hygiene.
-
Red Tongue: A bright red tongue can be a sign of several conditions, including:
- Scarlet fever: Often accompanied by a strawberry-like appearance.
- Vitamin deficiencies: Lack of vitamin B12 or folic acid.
- Kawasaki disease: A rare but serious condition that primarily affects children.
-
Black Tongue: A black, hairy tongue is usually caused by an overgrowth of bacteria and yeast. While it might look alarming, it's often harmless and temporary, resulting from poor oral hygiene, smoking, certain medications, or a soft diet.
-
Yellow Tongue: A yellow tongue can be an early stage of black hairy tongue or can indicate jaundice (a liver condition). Sometimes, it can be caused by the use of certain mouthwashes or medications.
It's important to note that these are just potential indicators, and it is best to consult a healthcare professional for an accurate diagnosis. A healthy tongue is usually pink. If you notice any significant changes in the color or texture of your tongue, you should seek medical advice.
