Yellow tongue: Causes and treatment

What is yellow tongue

Yellow tongue is a condition characterized by a yellowish discoloration on the surface of the tongue. It can be a sign of a variety of causes, usually related to habits, benign conditions or underlying medical problems. Although not always a cause for concern, in some cases it may indicate a health problem.

Causes of yellow tongue

1. Accumulation of dead cells and bacteria: poor oral hygiene can cause food debris, dead cells and bacteria to accumulate on the tongue, giving it a yellow appearance.
2. Consumption of certain foods or beverages: foods with dyes (such as candy) or beverages such as coffee or tea may temporarily stain the tongue.
3. Tobacco: Smoking or chewing tobacco may cause a yellow discoloration of the tongue.
4. Dry mouth (xerostomia): lack of saliva can hinder the natural cleaning of the tongue, allowing debris to accumulate.
5. Use of certain medications or mouthwashes: some medications (such as antibiotics) or mouthwashes with hydrogen peroxide, menthol or eucalyptus may alter the oral flora and cause discoloration.
6. Hairy tongue: a condition where the papillae on the tongue grow larger than normal, trapping bacteria and particles that can give it a yellow color.
7. Digestive or liver problems: Sometimes a yellow tongue may be related to digestive disorders, acid reflux or liver problems, such as jaundice.
8. Oral infections: mild bacterial or fungal infections may cause discoloration.

How to treat yellow tongue

• Maintain good oral hygiene: brush your teeth, floss and clean your tongue with a tongue cleaner or brush.
• Drink enough water to avoid dry mouth.
• Reduce or avoid the consumption of tobacco and foods with artificial coloring.
• Consult a health professional if the problem persists.

Is it bad to have a yellow tongue?

If the yellow tongue persists, is accompanied by other symptoms (such as fever, pain, yellow discoloration in other parts of the body, such as the eyes or skin), or if it is associated with discomfort, it is important to consult a physician or dentist.

How to clean yellow tongue?

1. Tongue brushing:
   1. Use a soft toothbrush or a specific tongue cleaner.
   2. Gently brush from the back of the tongue forward to remove build-up of debris, bacteria and dead cells.
   3. Rinse the brush or cleaner thoroughly after each pass.
2. Use a suitable mouthwash:
   1. Opt for an antimicrobial mouthwash that does not contain alcohol, which can dry out the mouth.
   2. Rinse your mouth twice a day to reduce bacterial growth.
3. Complete oral hygiene:
   1. Brush your teeth at least twice a day and floss to prevent bacteria from accumulating in the oral cavity.
4. Adequate hydration:
   1. Drink enough water to keep your mouth hydrated and help clean out debris accumulated on the tongue.
   2. If you suffer from dry mouth, consider using a saliva substitute or sugar-free chewing gum to stimulate saliva production.
5. Avoid tobacco and foods with dyes:
   1. Stop smoking or chewing tobacco, as these are important factors in tongue discoloration.
   2. Reduce consumption of foods and beverages that may stain the tongue, such as coffee, tea and foods with artificial coloring.
6. Use baking soda (optional):
   1. Mix a small amount of baking soda with water to form a paste.
   2. Gently rub the tongue with this mixture to neutralize acids and remove residues.
7. Consult a professional:
   1. If the yellow color persists after improving oral hygiene or if you notice other symptoms (such as pain, persistent bad breath or changes in the texture of the tongue), consult a dentist or physician.
