A white tongue can be an indication of various underlying health conditions, and while it is often harmless, it can sometimes signal a more serious issue. The tongue may appear coated in white patches or have an overall white appearance due to a buildup of debris, bacteria, and dead cells. This can be caused by multiple factors, ranging from minor concerns to more significant health conditions.

This is a fungal infection caused by an overgrowth of Candida yeast in the mouth. It often appears as creamy white patches on the tongue, inner cheeks, and throat. It is more common in people with weakened immune systems, those taking antibiotics, diabetics, and denture wearers.

When the body lacks sufficient hydration, saliva production decreases, leading to a dry mouth. This dryness can cause a buildup of bacteria and dead cells on the tongue, resulting in a white coating.

Not brushing the tongue regularly can lead to the accumulation of food particles, bacteria, and dead cells, which can create a white film over the tongue’s surface.
