Toddler Has Yellow Tongue? When to Worry

Yellow coating on the tongue is a common symptom in children because very often they neglect oral hygiene. Yellow coating on the tongue is an unsightly condition, which belongs to non-specific symptoms, ranging from various diseases.

A healthy tongue has a light pink color, and it is elastic and moist. Any deviations from the norm indicate some disturbances in the functioning of the body. Some are harmless and easy to remove; others require more attention.

Symptoms associating with a yellow tongue

Many symptoms are linking to yellow tongue in children and giving information about the coloration. The symptoms for yellow tongue may include:

  • Orange or yellow spots.
  • Thicker saliva.
  • Dry mouth
  • Bad breath
  • Sores in the mouth.
  • Halitosis.
  • Sore throat.
  • Tongue fluffy and rough to the touch.
  • Fever.

Lack of oral hygiene

Poor oral hygiene, either by doing it incorrectly or not doing it, is the leading cause of the yellow tongue. The hygienic deficit will cause bacteria to accumulate in the child’s mouth and on the surface of the language. Poor oral hygiene causes symptoms such as coloration, halitosis, and possible oral problems. Using tongue cleaners helps prevent the buildup of bacteria occurring when food stays between the teeth. The tongue cleaner is useful to avoid bacteria buildup but does not need scraping too hard.

Disruption of the digestive tract

An unbalanced diet, such as abuse of fatty, spicy foods, or fast food, threatens toxins accumulating in the human body—the formation of a white-yellowish coating at the base of the tongue results.
Symptoms: loss of appetite, nausea, vomiting, pain in the duodenum, heartburn, bad breath. The yellowness of a light shade (white-yellow or gray-yellow plaque) at the central part of the tongue.

Colds and infections

Colds or upper respiratory infections like sinusitis can force the child to breathe through the mouths instead of the noses. It causes dry mouth, even inflammation of the papillae, increasing the number of bacteria in the mouth. Therefore, causing it to turn yellow with the characteristic of coloration. Often involves an excessive amount of mucus in the back of the throat in which many bacteria are present.

Products with abrasives

Many kinds of toothpaste and mouthwashes contain substances containing abrasives or caustics, such as chlorhexidine, sodium lauryl sulfate (SLS), or menthol. Chlorhexidine is often a prescription of medicine for oral infection. The substance does not distinguish between good and bad bacteria, which disrupts the oral flora. Mainly when you use oral products containing chlorhexidine for a long time, the mouth will not have a chance to recover. Chlorhexidine also causes the yellowing of the tongue.

Adding of SLS substance to toothpaste for the caustic effect may injure harmful substances. The content of SLS makes small wounds in the mouth. The Small wounds attract bacteria, which convert blood and proteins into smelly odors and a yellow deposit. The scars cause minor infections in the mouth and attracting bacteria.

Fungal infection

A slightly yellowish tongue often accompanying the furry feeling in the mouth can indicate a fungal infection. The infection triggers the yeast “Candida albicans,” also known as “thrush,” “candidiasis,” or in babies as “diaper fungus.”

Candida albicans are also often found on healthy skin or mucous membranes, but under certain conditions, the fungi multiply and cause inflammation of the skin or mucous membranes. Triggers include general weakness in the body’s defenses and taking antibiotics or glucocorticoids.

Oral thrush (oral candidiasis)

When the yeast candida is only active in the mouth, you speak of oral thrush. Newborn babies, in particular, can suffer or get a yellow tongue. The infection is mild and hardly causes serious complications.


Jaundice is a syndrome indicating by a yellowish in the tongue or coloration of the language. The coloration also affects the skin, eyes, sclera, and body fluids. It occurs when the level of bilirubin in the blood reaches 3 mg%.

Jaundice is a frequent phenomenon in newborns, which affects almost 60% of term babies and 80% of premature babies. The cause of its spread in the blood is generally due to the excessive destruction of red blood cells. The factor occurs, for example, in some forms of anemia, or reducing the capacity of the liver. Jaundice should not be of particular concern unless the obvious symptoms go along with widespread pain. Pain in the mouth or the right flank. With an increase in direct bilirubin leading to an obstruction of the biliary tract. If the child has other symptoms such as nausea and vomiting, the risk may be acute viral hepatitis.


Bacteria are present everywhere, including the mouth. But when they occur in large quantities, they interfere with the oral flora. The child experience a yellow deposit on the tongue. Bacteria thrive exceptionally well in a dry mouth without oxygen and multiply. The bacteria release sulfur compounds, which cause bad breath and a yellow tongue to occur.

The bacteria not only cause unpleasant breath and a tongue which looks dirty. They can also move to other parts of the mouth, such as the tonsils, causing inflammation in a child. It is, therefore, essential to remove the yellow deposits on the tongue before the bacteria cause further mouth problems.


Apart from brushing the teeth, don’t forget to clean the tongue. Avoid sweets and food stuck in the mouth. Guiding the child on how to brush the teeth after each meal and rinsing the mouth with fluids. There is a need to visit the dentist to check occasionally or to eliminate any outbreaks of bacteria.

Tooth decay is a common problem in children. The yellow color on the tongue is not a condition that requires prompt medical consultation, although it is worth excluding significant causes for the changes. It also promotes colonization of the language by bacteria, so you need to eliminate such habits as soon as possible. Proper oral hygiene needs observation as it is accessible in children to catch the infection if the yellow coating persists, consulting a doctor to rule out any vitamin deficiencies in the child.
