A white tongue can be caused by a buildup of bacteria, dead cells, and debris on the surface of your tongue. This is called a coated tongue and is usually harmless. Even if you brush your teeth regularly, you might still have a white tongue if you don't brush your tongue as well.
Here are some other possible reasons why your tongue might be white even after brushing:
1. Poor Oral Hygiene
- Not brushing your tongue: Brushing your tongue helps remove bacteria and debris that can cause a white coating.
- Not flossing regularly: Flossing helps remove food particles and plaque that can contribute to a white tongue.
- Not rinsing your mouth after brushing: This can leave behind particles that can cause a white coating.
2. Dry Mouth
- Dehydration: Not drinking enough water can lead to dry mouth, which can make it easier for bacteria to grow on your tongue.
- Medications: Some medications can cause dry mouth as a side effect.
- Medical conditions: Certain medical conditions, such as Sjögren's syndrome, can also cause dry mouth.
3. Smoking
- Smoking: Smoking can stain your tongue and make it appear white.
4. Oral Thrush
- Oral thrush: This is a fungal infection that can cause a white, cottage cheese-like coating on your tongue.
5. Other Conditions
- Leukoplakia: This is a condition that causes white patches to form on the tongue and inside the mouth.
- Lichen planus: This is a condition that can cause white patches and sores on the tongue.
If you are concerned about a white tongue, it is important to see a dentist or doctor. They can help determine the cause and recommend treatment if necessary.
