Why is a Tongue Evaluation Important?

Your mouth is one of your body’s most important warning systems. Tongue lesions may indicate a local disease process or an overall systemic issue. Approximately 15.5 percent of US adults present with tongue lesions according to the National Health and Nutrition Examination Survey. This percentage increases with tobacco use and if an individual wears dentures. It is important that everyone is comfortable doing a tongue evaluation on themselves. After you do it once or twice, you will see how quickly it can be done.

How to evaluate your own tongue?

In between dental visits, it is important to evaluate your tongue for any changes. This is easily done in four steps:

  1. Look at the top of your tongue for any new areas of discoloration or growths.
  2. Use the back end of your toothbrush to gently depress the center of your tongue and say Ahh- evaluate the back of your tongue near your throat.
  3. Use a clean facecloth to gently grab the tip of your tongue and pull it gently out and to each side. Look at the side border of the tongue for any changes.
  4. Lift up your tongue to the roof of your mouth so that you can visualize the under-surface of your tongue. Also, use this opportunity to evaluate the floor of your mouth.
  5. If you see anything unusual or if you have new and unexplained pain and or symptoms, contact your dentist for an evaluation.

Here are some common tongue conditions:

Median Rhomboid Glossitis

Presents as a smooth shiny lesion in the central part of the tongue. May be asymptomatic but patients can have a burning or itching sensation. A yeast infection is thought to be the cause of this condition.

Benign Migratory Glossitis

Also known as geographic tongue. Is an inflammatory condition characterized by alternating raised plaques and smooth, atrophic areas. The lesions are “migratory” and can change over hours. Etiology is unknown but an association with psoriasis has been found.

Atrophic Glossitis

Presents as a smooth or glossy appearance partially or throughout the dorsum of the tongue. Typically due to a nutritional deficiency or an underlying disease or medication use.

Hairy Tongue

Benign condition with obvious discoloration (black, tan, white) on the dorsum of the tongue. Can be caused by smoking, xerostomia, poor oral hygiene, excessive coffee/tea consumption, and medications. Treatment involves discontinuation of the responsible agent and/or gentle tongue scraping.

Oral Hairy Leukoplakia

Commonly presents as a white, asymptomatic, corrugated plaque on the lateral border of the tongue that does not rub off. Is an Epstein Barr infection found in immunocompromised individuals especially those with concomitant HIV infection?

Leukoplakia

Adherent white patch found anywhere in the mouth but commonly found on the tongue and the floor of the mouth. Strongly associated with tobacco use but not necessary to occur. A biopsy is necessary to rule out a malignancy.

Squamous Cell Carcinoma

The most common oral malignancy. Can have a varied presentation: patch, nodule, or ulcer. Can be red or white or a mixture of both. Found most commonly are the lateral and ventral surfaces of the tongue as well as the floor of the mouth. A biopsy is indicated as soon as a lesion is identified.
