There are many possible causes for white tongue, and in some cases, it comes with an unpleasant odor and mouth dryness. To get rid of it, sometimes you just need to brush your teeth. But what should you do if that doesn’t help?
This article is for informative purposes only and can’t replace the advice of a specialist.
What white tongue is
The white film may cover the entire tongue, part of it, or appear as spots. At the same time, an unpleasant odor and taste in the mouth may appear. It looks as if there are small white hairs on the tongue’s surface. In fact, they are buds covered with organic particles, bacteria, and dead cells.
White plaque on the tongue (which can also be yellow) may appear for different reasons, like due to irritation or because of an infection. It usually disappears after several days. If the situation doesn’t change for several weeks, and it’s painful to eat and talk, it’s best to see a doctor.
It’s important to note that the plaque may not only be white. While a pink tongue is normal, a brown tongue means the person drinks too much coffee or tea. A yellow tongue means there’s something wrong with the liver, and a red tongue is a sign that the person lacks vitamin B.
Why the tongue becomes white
Usually, the tongue becomes white due to bacteria, leftover bits of food, or dead cells that get stuck in between the buds. Because of this, the buds may increase in size or become inflamed. This is how white spots on the tongue’s surface appear.
Sometimes, the plaque appears due to an illness. For example, the geographic tongue is also a condition where white spots appear on the tongue. It’s quite rare, and the causes are unknown, but the condition itself is often connected to eating foods that irritate the tongue. It may also be a reaction to stress, an illness, or hormonal changes.
Why white plaque appears on the tongue
There are some things that make the appearance of white plaque on the tongue more probable:
- Age
- Taking antibiotics (white-yellow plaque appearing when there’s a fungal infection in the mouth)
- A diet that’s lacking enough fruits, vegetables, vitamin B12, and iron
- A weak immune system
- Bad mouth hygiene
- Dental prosthetics or other objects that can damage the tongue
- Dehydration and mouth dryness
What piercings have to do with white tongue
Right after piercing the tongue, there might be some white film present. This happens because the number of bacteria on the tongue increases, and it’s normal. Antibacterial mouthwash will help you get rid of it. Plus, there might be a ring around the piercings, which is normal too, and it means the tissue is healing.
If the plaque appears due to an injury (including piercings), the healing should take around 1.5 weeks. You should avoid irritants, such as hot, spicy, or sour foods and drinks.
How to get rid of white tongue at home
- Practice good mouth hygiene.
- Drink enough water.
- Brush your teeth using a soft toothbrush.
- Use a mild fluoride toothpaste — one that doesn’t contain sodium lauryl sulfate.
- Use fluoride mouthwash.
- Brush your tongue or use a tongue scraper to remove the white coating.
- Drink cold drinks through a straw.
- Avoid food and drinks that are spicy, salty, acidic, or very hot in temperature.
Who to talk to if you’re worried about your white tongue
- Your dentist can help you remove the white film from the tongue and prescribe medications if needed.
- Your GP can diagnose the tongue, prescribe you certain medications and determine if the white tongue is an indicator of a more serious issue.

Can dogs really detect Covid-19 infections faster and more accurately than a lateral flow test?
Results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner – so no need to swab your throat or nose
Dogs can detect Covid-19 faster and more accurately than a PCR test, a new study shows.
Researchers looked at the ability of canines to recognise the virus and its variants, even when they are obscured by other viruses, like those from common colds and flu.
More than 400 scientists from over 30 countries contributed to the study as well as 147 scent dogs, according to the findings published in the Journal of Osteopathic Medicine.
After analysing many studies covering both field and clinical experiments, Professor Dickey and Junqueira found that dogs who are trained to sniff out scents are “as effective and often more effective” than antigen tests.
A total of 53 dogs were trained to sniff out Covid scents, while 37 were not and scientists found that the dogs that were not trained were in some cases “slightly superior” to those that were pre-trained.
“The previously untrained dogs have the advantage that they are not as prone to indicating on scents other than the Covid–19 associated scent,” the paper said.
The results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner. This means you won’t need to put a swab in your throat or nose.
How can dogs detect the virus?
This essentially comes down to the dog’s highly evolved nose with its ability to sense out smells quicker.
Dogs possess up to 300 million olfactory receptors in their noses, compared to about six million in humans. And the part of a dog’s brain that is devoted to analysing smells is about “40 times greater” than humans. Canines also have ‘neophilia’, which means they are attracted to new and interesting odours
And so, with all these enhancements, dogs can detect very low concentrations of odours associated with Covid infections.
“They can detect the equivalent of one drop of an odorous substance in 10.5 Olympic-sized swimming pools,” Professor Dickey said. “For perspective, this is about three orders of magnitude better than with scientific instrumentation.”
Scientists also found that in some cases, the animals were also able to detect the virus in pre-symptomatic and asymptomatic patients, “whose viral load was too low for conventional tests to work.”
Professor Dickey has said that dogs can also differentiate Covid and its different variants in the presence of other respiratory viruses. This included the common cold or flu.
“They’re much more effective. In fact, one of the authors that we quote in the paper commented that the RT-PCR test is not the gold standard anymore. It’s the dog. And they’re so quick,” he added. “They can give you the yes or no within seconds if they’re directly smelling you.”
How was the study conducted to see if dogs can really detect Covid-19?
In some studies, the dogs gave a person a quick sniff, sitting down to see if the person has Covid. In another study, the dog was given a sweat sample to smell for a few minutes.
The press release has said that scent dogs, such as beagles, basset hounds and coonhounds are the ideal candidates for sniffing out the virus, given their “natural tendencies to rely on odours to relate to the world.”
But the studies which the researchers analysed showed a variety of dogs were up for the challenge and were able to sniff out the Covid odour. With a few weeks of training, puppies, older dogs, purebred and mixed breeds, both male and female were able to sniff such odours out and “all performed admirably,” the Eureka Alert press release said.
Although there has been success with dogs detecting such viruses, researchers believe there are still many challenges with using dogs for medical diagnoses.
“There’s quite a bit of research, but it’s still considered by many as a kind of a curiosity,” said Professor Dickey.
In conclusion, Professor Dickey and Junqueira said after reviewing the studies, believe that scent dogs deserve “their place as a serious diagnostic methodology that could be particularly useful during future pandemics, potentially as part of rapid routine health screenings in public spaces.”
“Perhaps, most importantly, we argue that the impressive international quality and quantity of COVID scent dog research described in our paper for the first time, demonstrates that medical scent dogs are finally ready for a host of mainstream medical applications,” they added.
