What Does Your Tongue Reveal About Your Health?


Our tongue is probably the least thought about organ in our body. Most of us know that the tongue allows us to taste food and helps us form words, but is there anything else that’s worth knowing about this fleshy, muscular organ?

In fact, there is. As it turns out, our tongue can reveal important facts about our health. When we go and see our doctor, they’ll often have us open our mouth and extend our tongue. They do so for good reason: our tongue is one of the most visible representations of our overall health.

The best way make a determination of our health while examining our tongue is to match its appearance to potential causes. With that said, let’s take delve into some common health conclusions that can be made when the tongue appears or feels a certain way.

What does your tongue reveal about your health?

1. Tongue contains brown or black fuzz

While this look can be alarming and deeply troubling, it’s actually just a matter of oral health. A tongue that contains brown or black fuzz is the a strong indication of bad oral hygiene.

Papillae –tiny bumps we see on our tongue – normally become worn down simply by eating and drinking. However, they can sometimes experience overgrowth which makes them prone to concentrations of bacteria and discoloration. Doctors point out that the root causes of this visually unappealing condition are normally smoking, drinking coffee or dark teas, or just bad dental hygiene.

The remedy is to simply eliminate the habit that caused it. Stop smoking, drink less coffee or tea, and practice good hygiene. Tongue scrapers are also available that make the removal of fuzz easier.

2. Visible patches of white

A frequent symptom among tobacco users, patches of white underneath the tongue, around the gums, and on the insides of our cheeks (called leukoplakia) are usually caused by an irritant of some sort.

Although leukoplakia isn’t normally dangerous, is can be potentially serious. Most patches of leukoplakia are benign (non-cancerous), but some can show early signs of cancer. Tobacco users, especially smokers, that display these lesions have between a 5 to 17 percent chance of the patches becoming cancerous. Doctors point out that these precancerous patches will normally disappear when tobacco use is stopped.

3. Burning sensation of the tongue

Burning sensations of the tongue are quite common – 15% of people will experience it sometime in their life. Women are seven times more likely to get a burning sensation, as it sometimes occurs post-menopause.

If the tongue appears normal yet burns, it can mean a couple of different things. Hormonal changes, wrong toothpaste and allergies from toothpaste can create a burning sensation. Many toothpastes get their foamy appearance from an ingredient called sodium lauryl sulfate (SLS), which has been known to cause stinging and burning – even suddenly. In this instance, it’s advisable to change to a paste that does not contain SLS (Sensodyne is a popular brand for this reason).

In many cases, the burning sensation will subside without intervention. For cases when the symptom is persistent, doctors will often prescribe antibiotic rinses or neuropathic medication.

4. “Geographic tongue”

Affecting roughly between 1 to 14 percent of the population, Geographic tongue is a medically coined term that refers to a sporadic, rutted appearance resembling bumpy terrain. Fortunately, this is a very common, normal condition that doesn’t normally indicate any health concerns.

Experts are somewhat unclear about what causes Geographic tongue, although it’s believed that the growth and degeneration of taste buds could play a role. When this growth and degeneration of is uneven, it creates a visually noticeable effect.

This condition of the tongue doesn’t usually require medical intervention. However, if they become painful it’s advisable to see a doctor, who will usually then prescribe some type of anti-inflammatory steroid paste or antihistamine rinse.
