A white tongue can happen for many reasons and may come with bad breath or a dry mouth. Sometimes, brushing your teeth is all it takes to solve the problem, but what if it doesn’t go away?
What a white tongue looks like
The white coating can cover the whole tongue, parts of it, or appear as patches. It may also bring an unpleasant taste or smell. The surface might look like it has small white hairs, which are actually taste buds. These buds can trap bacteria, food particles, and dead cells, forming the white layer.
Infections or irritation often cause a white tongue, and it usually clears up in a few days. If it persists for weeks or becomes painful while eating or talking, it’s best to visit a doctor.
What the colors of your tongue mean
A healthy tongue is pink, but other colors can indicate issues. A brown tongue often means excessive coffee or tea. A yellow tongue might point to liver problems, while a red tongue can signal a vitamin B deficiency.
Why a white tongue appears
The white coating forms when bacteria, food particles, or dead cells stick between the buds on the tongue. This can make the buds swell or become inflamed. In some cases, it’s caused by conditions like a geographic tongue, where white patches appear randomly. Triggers for this include irritating foods, stress, or hormonal changes.
Certain factors increase the likelihood of a white tongue:
- Age
- Antibiotics
- Lack of fruits, vegetables, or nutrients like vitamin B12 and iron
- Poor oral hygiene
- Dehydration
- Dental prosthetics
How to get rid of a white tongue
- Practice good oral hygiene
- Drink enough water
- Use a soft toothbrush and gentle toothpaste
- Try a tongue scraper
- Avoid irritants like spicy or acidic foods
If the issue continues, consult a dentist or GP. They can assess your tongue and provide the right treatment.
