Leukoplakia are white patches that develop on the soft tissue of the mouth. This can include gums, tongue, or inner cheeks. The patches form over the course of weeks or months.
There are different types of leukoplakia that may appear in different areas of the body, such as the vulva in females, esophagus, or bladder. The information in this fact sheet will focus on oral leukoplakia.


Leukoplakia usually results from irritants, such as:

Risk Factors

Leukoplakia is more common in men after age 65. Other factors that may increase your chance of leukoplakia include:


Leukoplakia causes patches on the tongue, gums, or inside of the cheeks. These patches may appear as:
There may be pain or signs of infection. The patches may also be sensitive to touch, heat, or spicy foods.
In some cases, leukoplakia looks like oral thrush, which is an infection also associated with HIV infection and suppressed immune function.

Untreated leukoplakia can turn into cancer. Some types of leukoplakia carry a higher risk of turning into cancer than others. If you have leukoplakia, talk to your doctor about your cancer risk and how often you should be evaluated or tested.


Your doctor will ask about your symptoms and medical history. A physical exam will be done, including the area where the patches are. In most cases, oral leukoplakia can be diagnosed during an oral exam. Your doctor may do a brush biopsy to check for cancer. The biopsy sample is evaluated under a microscope.


Talk with your doctor about the best treatment plan for you. Treatment options include:


If the patches do not fade as expected, your doctor may advise:
  • Topical medications or solutions that are applied to the patches
  • Medicated mouthwashes
  • Oral medications, such as retinoids, vitamin A, beta carotene, or lycopene
  • Antiviral medications—if the leukoplakia is due to viral infection (more common in people with suppressed immune function)
