Quick answer
What is Leukoplakia?
Leukoplakia is a white or greyish patch that develops on the lining of the mouth — such as the inside of the cheeks, gums, or tongue — which cannot be scraped or rubbed off (unlike, for example, oral thrush, which usually can be). It is the mouth's response to long-term irritation, and the most common causes are smoking or other tobacco use, and sometimes friction (such as from a rough tooth or denture) or other irritants.
- How it is treated: Assessment is the first step: a dentist or doctor examines the patch, and, because it is not possible to tell just by looking whether a patch is entirely harmless, a sample (biopsy) is often taken to examine the cells under a microscope and check for any concerning changes.
- Self-care: Stopping smoking and other tobacco use is the most important measure (and can help some patches improve), along with limiting alcohol, fixing any rough tooth or denture, good oral hygiene, and attending regular dental check-ups and any recommended monitoring.
- When to seek help: See a dentist or GP about any white (or mixed red and white) patch in the mouth that does not rub off and does not go away, so it can be assessed and, if needed, biopsied and monitored.
What it is
Leukoplakia is a white or greyish patch that develops on the lining of the mouth — such as the inside of the cheeks, gums, or tongue — which cannot be scraped or rubbed off (unlike, for example, oral thrush, which usually can be). It is the mouth's response to long-term irritation, and the most common causes are smoking or other tobacco use, and sometimes friction (such as from a rough tooth or denture) or other irritants. It is usually painless and often found by chance or by a dentist. In most cases leukoplakia is harmless (benign). However, its importance is that a small proportion of leukoplakia patches can, over time, show changes that could lead to mouth cancer — so it is regarded as a condition to monitor, and sometimes to biopsy, rather than ignore. A speckled (mixed red and white) appearance, or a patch that changes, is of more concern. Because it can be a warning sign, any persistent white patch in the mouth should be checked.
How it is treated
Assessment is the first step: a dentist or doctor examines the patch, and, because it is not possible to tell just by looking whether a patch is entirely harmless, a sample (biopsy) is often taken to examine the cells under a microscope and check for any concerning changes. Removing the cause of irritation is central — most importantly stopping smoking and other tobacco use (which can allow some patches to improve or resolve), and fixing any rough tooth or denture. Depending on the biopsy findings and the appearance, the patch may then be monitored over time with regular reviews, or, in some cases, removed (for example by minor surgery or laser) — particularly if it shows worrying changes. Ongoing monitoring is important because of the small risk of change, and any new symptoms (such as a lump, ulcer, pain, or the patch changing) are reported. The reassuring message is that most leukoplakia is harmless, but because a small proportion can change, any persistent white patch in the mouth should be checked and, where advised, monitored.

Answers
Leukoplakia: frequently asked questions
Is leukoplakia cancer?
Most leukoplakia is harmless. However, a small proportion of patches can, over time, show changes that could lead to mouth cancer, which is why it is assessed (often with a biopsy) and monitored rather than ignored. A speckled or changing patch is of more concern.
What causes white patches in the mouth?
Leukoplakia is usually the mouth's response to long-term irritation — most commonly smoking or tobacco use, and sometimes friction from a rough tooth or denture. Stopping the cause can help, and any persistent white patch should be checked.
