Leukoplakia: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 23, 2026.
What kind of doctor treats Leukoplakia?
A dentist or a primary care doctor can check a white patch in the mouth. An oral surgeon or an ear, nose and throat doctor may do a biopsy, where a small piece of the patch is tested. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is leukoplakia?
Leukoplakia is a white patch or patches on the tongue, in the mouth or on the inside of the cheek. The patches are thick and whitish. They are caused by extra cell growth.
Leukoplakia is usually harmless. In some cases, the patches may be an early sign of cancer. It is more common in older adults.
A type called hairy leukoplakia is different. It is caused by the Epstein-Barr virus and is seen mostly in people with HIV/AIDS or another weak immune system.
Symptoms
Leukoplakia patches are usually on the tongue and the insides of the cheeks. They can also form on the gums. The patches are:
- Most often white or gray.
- Uneven in shape.
- Slightly raised, with a hard surface.
- Sometimes marked with red areas.
- Not able to be scraped off.
The patches are not usually painful. They can hurt when they touch acidic or spicy food. Hairy leukoplakia causes fuzzy white patches, often on the sides of the tongue. They look folded or ridged.
Causes and who gets it
The exact cause is not known. Irritation may play a part. Common sources of irritation include:
- Rough teeth.
- Rough places on dentures, fillings and crowns.
- Smoking or other tobacco use, especially pipes.
- Holding chewing tobacco or snuff in the mouth for a long time.
- Drinking a lot of alcohol.
Leukoplakia is common among tobacco users. An ill-fitting denture or the habit of chewing the inside of the cheek can also irritate the mouth.
How doctors diagnose it
A dentist or doctor looks at the patch. They can rule out other causes, such as oral thrush (a fungal infection of the mouth) or cheek biting. A patch that can be wiped away may be thrush.
A biopsy confirms the diagnosis. A small piece of the patch is removed and checked for abnormal cells. The results may show changes that point to oral cancer.
Treatment
Treatment is not always needed. You will have regular check-ups to make sure the patch is not getting bigger. The goal of treatment is to get rid of the patch.
Removing the source of irritation may make the patch go away. Steps include:
- Treating rough teeth, uneven dentures or fillings as soon as possible.
- Stopping smoking and other tobacco use.
- Stopping alcohol or drinking less.
If that does not work, a provider may suggest medicine put on the patch or surgery to remove it. Surgery is sometimes used if there is a chance the patch could become cancerous. A laser or a scalpel can be used. The area may be numbed first, and the mouth should heal quickly.
For hairy leukoplakia, antiviral medicine usually makes the patch go away.
When to see a doctor
See a dentist or doctor if you have a white patch in your mouth that does not go away. Get it checked, because the patch can be an early sign of cancer. Also go if you have pain or discomfort in your mouth that is not going away.
If you have a weakened immune system, such as with HIV or after an organ transplant, get any white patch on your tongue checked.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can look at a white patch, talk about tobacco and alcohol use, and refer you to a dentist or specialist for a biopsy. They can also help you keep up with regular check-ups.
Common questions
Is leukoplakia cancer?
Not usually. Leukoplakia is usually harmless, but in some cases the patches may be an early sign of cancer. This is why a dentist or doctor should check any patch that does not go away.
Can leukoplakia go away on its own?
Sometimes. Patches in the mouth often clear up in a few weeks or months after the source of irritation is removed.
Can you scrape off leukoplakia?
No, leukoplakia patches cannot be scraped or rubbed away. A white patch that can be removed could be oral thrush, a fungal infection.
Does leukoplakia hurt?
Usually not. The patches are not usually painful, but they can hurt when they touch acidic or spicy food.
What is hairy leukoplakia?
Hairy leukoplakia is a type of leukoplakia caused by the Epstein-Barr virus. It causes fuzzy white patches, often on the sides of the tongue, and is seen mostly in people with a weak immune system.
