Have you ever noticed that your tongue doesn’t always look the same? Sometimes it might be pink and healthy, while other times it can appear discoloured, leaving you wondering what’s going on. Well, fear not! In this blog post, we’ll explore some common reasons why your tongue might be discoloured and what you can do about it.

Food and Drinks

One of the most common culprits for a discoloured tongue is what you eat and drink. Certain foods and beverages like coffee, tea, red wine, and brightly coloured candies can stain your tongue temporarily. Usually, these stains will fade as your tongue naturally sheds its outer layer of cells. So, if you’ve recently indulged in some colourful snacks, give it a little time – your tongue will likely return to its normal shade.

Poor Oral Hygiene

Neglecting your oral hygiene can lead to a discoloured tongue. When you don’t brush and floss regularly, bacteria can accumulate on your tongue’s surface, causing it to appear white or yellowish. This condition, known as oral thrush, can be treated with proper oral care and, in some cases, antifungal medications.


If you’re a smoker, the chemicals in cigarettes can stain your tongue and leave it looking discoloured. Not to mention, smoking is harmful to your overall oral health. Quitting smoking can not only improve the colour of your tongue but also benefit your entire mouth.

Medical Conditions

Certain medical conditions can also cause tongue discoloration. For instance, a black or brown tongue might indicate a condition called “black hairy tongue,” often caused by poor oral hygiene, tobacco use, or specific medications. On the other hand, a yellow or greenish tongue might be a sign of liver or gallbladder issues.


Not drinking enough water can lead to a dry mouth, which can cause your tongue to turn white or pale. Staying well-hydrated is essential for overall oral health and can help prevent tongue discoloration due to dehydration.

In conclusion, a discoloured tongue can be caused by various factors, including your diet, oral hygiene habits, smoking, medical conditions, and hydration levels. If you’re concerned about the colour of your tongue and it doesn’t improve with improved oral care and hydration, it’s a good idea to consult a dentist or healthcare professional for a thorough examination.

Maintaining good dental hygiene is crucial to prevent tongue discoloration and other oral health issues. Regular dental check-ups and cleanings can help keep your tongue and mouth in tip-top shape. 

Remember, a healthy tongue is a reflection of your overall health, so take good care of it!
