Yellow Tongue Causes & TreatmentA yellow tongue is not a disease but it is a sign which indicates a clinical problem. It is important to figure out the cause to have the accurate treatment and avoid more complications. Usually, it is a harmless condition and will go away on its own in time. Yellow coated tongue tends to be common in the morning when you wake up i.e. Yellow tongue in the morning that could be yellow green, yellow white or orange. The problem can also be present at night or always. It all depends on what could be behind it.

Causes of Yellow Tongue :

Normally, there is a balance between formation of new cells and shedding of dead cells and bacteria on the tongue to have the normal coating. However, the most common cause of yellow tongue is due to accumulation of dead cells and bacteria on the upper surface of the tongue. Bacteria release pigments that can turn your tongue yellow. Food, tobacco, and other substances can also get trapped on your tongue and turn it yellow because of poor oral hygiene and improper tongue brushing.

The yellow tongue has different causes and forms and may be due:

Tooth extraction, or tonsillectomy: A yellow tongue may follow a piercing, tooth extraction, or tonsillectomy as a result of papillae inflammation. It’s important that you follow proper oral care after these procedures to reduce the risk of infection.

Pregnancy: It is common to see a yellow tongue in pregnant woman as it may be related to hormonal changes.

Black hairy tongue “yellow furry tongue“: it is a harmless condition occurs due to enlargement, roughness and swollen of tongue papillae “which located on the upper surface of the tongue” and this leads to more accumulation of epithelial squamous and proliferation of chromogenic (color-producing) microorganisms giving the black or yellow coating on the tongue.

A soft diet is recommended as normal food has an abrasive action on the tongue, which keeps the filiform papillae short.

When your tongue is yellow due to a black hairy tongue, you are likely to have other symptoms such as: metallic taste, bad breath “halitosis“ and itchy sensation especially if your papillae have overgrown.

Dry mouth and mouth breathing:  Normally, saliva wash out the bacteria and food debris from the mouth and help in prevention of tooth decay. Dry mouth may occur due to Sjogren syndrome, diabetes, radiation, chemotherapy and mouth breathing.

Geographic tongue: is an inflammatory condition of the mucous membrane of the tongue, usually on the inner surface (Dorsal Surface). It is characterized by areas of smooth, red depapillation (loss of tongue coat) which migrate over time. The name comes from the map-like appearance of the tongue.

This lesion usually changes in shape, size and migrates to other areas, sometimes within hours. The lesion’s patches are often red, but they can turn yellow too.

The cause of geographic tongue is unknown, but the condition is entirely benign and doesn’t represent oral cancer. Geographic tongue may also cause a burning sensation on the tongue.

Jaundice: is a disease where your skin, tongue and whites in your eyes become yellow.  It happens when your liver is damaged and can’t properly process the waste product bilirubin. Bilirubin is a yellow pigment that’s produced when red blood cells break down. When bilirubin builds up in the blood, your skin, whites of your eyes, and tongue can turn yellow.

Medicines that contain bismuth: Pepto-Bismol “which is used to treat diarrhea and relieve the symptoms of an upset stomach“ and other bismuth-containing medicines can turn your tongue colors that range from yellow to black.

Mouthwashes that contain oxidizing agents: Using a mouthwash that contains peroxide or menthol can turn your tongue color into yellow.

Tobacco smoke: Chemicals in tobacco smoke can make your tongue turn a yellow color.

Antibiotic use: The use of some antibiotics can cause yellow tongue due to an imbalance of microbes, which causes bacteria or yeast to grow.

Pregnancy: It is common to see a yellow tongue in pregnant woman as it may be related to hormonal changes.
