What your tongue colour reveals about your health—learn the surprising signs now!

Whenever we monitor our health, we often think about heart rate, blood pressure, and cholesterol levels. But there is a part of the body that can offer a wealth of information, and it is right under our nose—quite literally.

Your tongue, a vital organ for taste and speech, can also be a powerful indicator of your overall health.



Dr Deepak Aulak, a dentist and founder of the AI-powered dental app Toothfairy, emphasises the importance of paying attention to the colour of your tongue, as it could be signalling something significant about your health.

A healthy tongue is typically pink with small bumps known as papillae. However, colour variations can be early warning signs of health issues, some of which may require immediate medical attention.

Let us delve into what different tongue colours might indicate and why it is crucial to keep an eye on this often-overlooked health barometer.

White Tongue
A white coating or white spots on your tongue could be a sign of oral thrush, a yeast infection that develops inside the mouth. It can also indicate leukoplakia, which is a potential precursor to oral cancer.

Other conditions associated with a white tongue include anaemia and lichen planus. If you notice a persistent white colour on your tongue, it is advisable to consult a healthcare professional.

Yellow or Brown Tongue
Poor oral hygiene is often the culprit behind a yellow or brown tongue. This discolouration can also result from lifestyle habits such as smoking, excessive coffee or tea consumption, and alcohol use.

In some cases, a yellow tongue can be a symptom of jaundice, which is related to liver issues.

If you notice your tongue, skin, or eyes turning yellow, it is important to seek medical advice.

Orange Tongue
An orange hue on the tongue is less common but can occur due to poor oral hygiene or
consuming foods high in beta-carotene, such as carrots.

Certain medications, including some antibiotics, can also cause an orange discolouration.

Red Tongue
A red or ‘strawberry’ tongue can be a sign of vitamin deficiency, particularly a lack of
vitamin B12 or folic acid. Conditions such as scarlet fever, Kawasaki disease, and glossitis can also cause the tongue to appear red and swollen.

If you notice a sudden change to a bright red tongue, it is important to consult a doctor, especially if accompanied by other symptoms.



Grey Tongue
Grey discolouration may occur along with geographic tongue, where red patches with grey borders can appear.

Eczema sufferers and those on certain antibiotic or antifungal medications may also notice a greyish tongue.

Black Tongue
A black, hairy-looking tongue can be quite alarming, but it is often the result of an
overgrowth of papillae trapping food and bacteria. Poor oral hygiene, tobacco use, and certain medications are common causes.

While it may look serious, it is usually not harmful and can be fixed with improved oral care.

Purple Tongue
A purple tongue can indicate poor circulation or a heart condition. In children, it may be a sign of Kawasaki disease.

If you notice a purple discolouration, it is important to seek medical attention to rule out any underlying conditions.

Green Tongue
A green tongue is typically a sign of poor oral health, but it can also be caused by smoking, dry mouth, or due to certain medications.

Blue Tongue
A blue tongue is a serious sign of concern. It could indicate cyanosis, which means there is not enough oxygen in the blood. This can be due to respiratory or circulatory problems and requires immediate medical attention.

It is important to remember that while these signs can be helpful indicators, they are not
definitive diagnoses.

If you notice any unusual changes in the colour or appearance of your tongue, it is best to consult with a healthcare professional. Your dentist or GP can provide a thorough examination and appropriate advice.



Maintaining good oral hygiene is essential.

Brushing twice a day, flossing regularly, and visiting the dentist for routine check-ups can help prevent many of the issues associated with changes in tongue colour.

Staying hydrated, avoiding tobacco and excessive alcohol can also contribute to a healthy mouth and a pink, happy tongue.

Key Takeaways:
  • Dentist Dr Deepak Aulak emphasises that the colour of your tongue could indicate your general health status. Ignoring changes may risk your health.
  • A healthy tongue should appear pink with small bumps known as papillae, while other colours may suggest various health concerns or deficiencies.

In conclusion, your tongue can tell you more about your health than you think. By keeping an eye on its colour and texture, you can catch potential health issues early and seek the necessary treatment.

So next time you brush your teeth, take a moment to look in the mirror and say ‘Ahhh’—your tongue might have something important to say.
