Most of us don’t give much thought to a certain pink muscle we rely on every day. Whether we’re enjoying a warm drink or having a quick chat, it’s always there, helping us without complaint.

But some experts say there’s more to it than meets the eye. The truth might be hiding right on the surface—if you know what to look for.



A healthy tongue is typically pink with a slightly rough surface. That rough texture is caused by small bumps on the top called papillae. According to Sarah Ramage, a clinical director at Bupa, this is the normal appearance everyone should aim for.

Any deviation from this could be a sign of something more serious—either with your mouth or your entire body. Red or white patches on the tongue are one of the biggest warning signs. "Abnormal looking patches, lumps or spots could be a sign of mouth cancer," Ramage explained.

Red patches may indicate a condition known as erythroplakia. Meanwhile, white or gray patches may be leukoplakia. Both are considered potential precursors to mouth cancer if left untreated.


Dentists typically check for these signs during routine visits. If there is concern, they’ll refer patients to a GP or specialist. "Mouth cancer rates have increased by almost 60 percent in the last decade, so it's important to be aware of any changes," she added.

Another possible concern? White spots or lesions. If your tongue has creamy white areas that don’t brush off, it could be oral thrush. This is a fungal infection that, while usually harmless, can spread if not treated.

The infection may also lead to discomfort, pain, or even problems eating or drinking. The unpleasant taste or soreness often associated with thrush can also interfere with everyday habits. Color changes are also important to note.

A red tongue could mean there is “heat in the body like a fever or a hormonal imbalance,” said Montana-based dentist Dr. Leslie Anthony. A reddish-purple tongue may signal inflammation or infection. On the opposite end, a pale pink tongue might reflect vitamin deficiencies, a weakened immune system, or general fatigue.

These subtle changes can often go unnoticed, especially if you don’t check your tongue regularly.

The presence of a coating—whether white, yellow, gray, or black—can provide other clues. A thick coating typically reflects intestinal or digestive problems. A yellow coating may point to an infection brewing somewhere in the body.

A gray or black coating could indicate a chronic digestive issue or a much more serious problem. In some cases, a thick white coating may reflect poor blood circulation or even a yeast infection. Tongue shape can also reveal health insights.

A puffy tongue with scalloped edges—showing indentations or wavy marks—can suggest malabsorption of nutrients. If the tongue appears unusually thin, that may point to dehydration. In either case, these signs indicate your body isn’t functioning at its best, and intervention may be needed.

Some people may notice a patchy, map-like appearance on their tongue. This is known as geographic tongue. It appears when the tongue’s top layer doesn’t shed evenly. It leaves red, smooth spots that resemble continents on a map.

While it may look concerning, experts say it’s generally harmless.

So, how can you keep track of what your tongue is trying to tell you? Experts recommend inspecting your tongue before brushing, when it’s clean and residue-free. Pay attention to color, bumps, patches, and texture. If anything looks unusual and doesn’t go away within a week or two, it’s worth getting checked by a professional.

Proper tongue hygiene is key to good oral health. Just like your teeth and gums, your tongue needs to be cleaned regularly. Experts say brushing your tongue gently with a toothbrush can help.

Use a dab of toothpaste and clean from the back of the tongue toward the front. Be sure to rinse well afterward with mouthwash or water.

For those looking for a more thorough clean, a tongue scraper may be used. It helps peel away the layer of mucus and food debris that naturally forms. This may also reduce bad breath and improve your sense of taste. Keeping your tongue healthy also involves drinking enough water daily.


If you notice any sores, swelling, or strange coatings that persist, don’t ignore them. Your tongue might be sending you early clues about something serious.

Getting checked by a dentist or doctor could make all the difference.
