3 Common Tongue Issues
Posted on 9/15/2026 by Lakewood Dental Arts |
 Your tongue is a busy body! It helps you taste, swallow, and even speak. Because it's so active and exposed in your mouth, it's not uncommon for the tongue to experience some issues. Let's look at three common tongue conditions, what causes them, and what you can do.
Geographic Tongue
Imagine your tongue as a map. Geographic tongue, also known as benign migratory glossitis, makes your tongue look like it has patches with borders, similar to islands on a map. These patches are usually red and smooth, surrounded by a slightly raised, white border. The patches can change location, size, and shape from day to day, which is why it's called "migratory."
What causes this "map" to appear? The exact cause is unknown, but it may be related to stress, allergies, or certain foods. Some studies suggest a link with psoriasis. Most people with geographic tongue don't experience any pain, but some might feel sensitivity to hot, spicy, or acidic foods.
While there's no cure for geographic tongue, the good news is that it's usually harmless. If you're experiencing sensitivity, avoid foods that trigger it. Good oral hygiene, like brushing your teeth and tongue regularly, is always a good idea for overall oral health. If you're concerned about geographic tongue, talk to your dentist. They can help determine if treatment is needed or if the condition is related to an underlying cause.
Oral Thrush
Oral thrush, also known as candidiasis, is a fungal infection caused by an overgrowth of Candida yeast. This yeast naturally lives in your mouth, but sometimes it can multiply out of control, leading to an infection.
Thrush appears as creamy white lesions, usually on the tongue and inner cheeks. They can sometimes be painful and may bleed if scraped. You might also experience a cottony feeling in your mouth or a loss of taste.
Several factors can contribute to oral thrush, including a weakened immune system (like in infants or people with HIV/AIDS), diabetes, certain medications (like antibiotics or corticosteroids), and even wearing dentures.
Treatment for thrush usually involves antifungal medication, which may be a liquid you swish in your mouth and swallow, or a pill. Maintaining good oral health, managing underlying conditions like diabetes, and rinsing your mouth after using an inhaler can help prevent thrush.
Black Hairy Tongue
Despite its alarming name, black hairy tongue is usually a harmless, temporary condition. It occurs when the small bumps on your tongue, called papillae, become elongated and trap bacteria, food particles, and other debris. This buildup can give the tongue a dark, "hairy" appearance.
The color of the tongue can vary from brown to black, depending on the cause. Poor oral hygiene, smoking, certain medications (like antibiotics), and a soft food diet can all contribute to black hairy tongue.
The best way to get rid of black hairy tongue is to improve your oral hygiene. Brush your tongue regularly with a tongue scraper or toothbrush to remove the buildup. Quit smoking, and drink plenty of water to stay hydrated. In most cases, black hairy tongue will resolve on its own with good oral hygiene practices.
Taking care of your tongue is just as important as taking care of your teeth for optimal oral health. If you notice any unusual changes in your tongue, don't hesitate to talk to your dentist. They can help diagnose the problem and recommend the best course of action. |
