Researchers Explain What The Color of Your Tongue Says About Your Health

“Any discoloration, lumps, sores or pain (of the tongue) should be monitored and evaluated by a medical professional if they don’t go away within two weeks.” – Dr. Daniel Allan, Family Physician at the Cleveland Clinic

“Say Ah…”

Ever wonder why doctors examine your mouth during a regular checkup? Well, when the doc asks you to say “Ah,” they’re glancing at your tonsils and tongue.

You may have noticed that this routine doesn’t take too long – a few seconds, usually. That’s because doctors can gain valuable insight into the appearance of this muscle. Indeed, it reveals a lot about your wellness.

If you think about it, the tongue is often overlooked. It’s not visible to others (mostly); we don’t pay it much attention unless we’re brushing it, and, the tongue just kind of sits.

The tongue, however, is crucial to our health and function. Without it, we couldn’t eat, drink, taste, chew or talk.

In this article, we’re going to discuss what it can reveal about your health. As it turns out, it’s quite a lot.

Quick anatomy lesson

Our tongue doesn’t have “skin.”

Instead, it’s covered with a pink, moist tissue (mucosa) and maintained by a large flow of blood. The mucosa and high blood content give the tongue its red-pink coloration.

The tongue’s color provides the most valuable information. As such, its coloration is what we’re going to focus on here.

What Does Your Tongue Say About Your Health?

The tongue consists of three sections – the apex, body, and root. The apex is the tip; the body is the rest of it  extends back into the throat, and the root fixes it to the mouth’s base.

Abnormal Colors

As mentioned, a healthy tongue always has a red-pink hue. Certain colors that may be considered unusual include:

  • Black
  • Blue
  • Bright red
  • Purple
  • White
  • Yellow

White

A whitish color is by far the most common type of discoloration. It is often related to continued, poor oral hygiene. Other conditions that may cause whitening of the tongue include:

  • Canker sores: visible white sores on the tongue. Canker sores often contain white to yellowish lesions at the center. Though painful, canker sores are usually rather harmless. Repeated cases, however, should be examined to test for possible underlying conditions.
  • Leukoplakia: a condition associated with irritation caused by chewing tobacco. The condition causes cells called mucous membranes to inflame. The discoloration is evident when the apex of the tongue or inner cheek of the mouth shows whitish-grey patches.
  • Oral thrush (candidiasis): manifests from a yeast called Candida albicans. This yeast creates white, creamy textured patches on the surface. Thrush can happen to anyone, though people with a suppressed immune system, the very young, and the elderly are especially at-risk.

Black

Strange looking as it may be, medical conditions don’t typically cause a black tongue. Sometimes, the tongue may appear black by elongation of the papillae, small bumps on it’s surface. Black tongue can stem from certain OTC medications (e.g., antibiotics and bismuth), mouthwash products, lack of oral hygiene, or tobacco use.

Blue

A tongue that looks blue should always be considered a medical emergency. As is the case with other parts of the body, the color blue often indicates a cutoff of blood somewhere.

A blue tongue may be a sign of cyanosis, a serious condition that disrupts oxygen supply to our tissue. Cyanosis may be caused by blood disorders, blood vessel diseases, or cardiac conditions.

Bright red

Bright red coloring may be due to a couple of things. Glossitis, or inflammation of this muscle, is the most common. Bright red may also be a sign of nutrient deficiency. Family physician, Dr. Danial Allan, states “Folic acid and vitamin B-12 deficiencies may cause your tongue to take on a reddish appearance.”
