17655 Leukoplakia

Overview

Leukoplakia is a white or grey patch that forms on the inside of the mouth, such as the tongue, gums, or cheeks. It cannot be scraped off, and it is not the same as a common mouth ulcer. Most leukoplakia patches are harmless, but a small number can show early signs of mouth cancer, so a doctor or dentist should always check any white patch that lasts more than two weeks.

Leukoplakia is fairly uncommon. It is seen more often in men than in women, and it becomes more likely as you get older, especially after age 40.

It mostly affects adults over 40, particularly people who smoke, chew tobacco, or drink alcohol heavily. It can also appear in younger people, and very rarely in children.

Symptoms

Common symptoms

• A white or greyish patch on the tongue, gums, roof of the mouth, or inside the cheeks
• A patch that feels slightly raised, thickened, or rough
• A patch that is usually painless but may feel sensitive to hot, spicy, or acidic food
• Occasionally, the patch has red areas mixed in, which may need extra attention

Symptoms in children

• Leukoplakia is very rare in children. When it happens, the patches look the same as in adults: white or grey areas inside the mouth that do not rub or scrape off.
• Because it is uncommon, any white mouth patch in a child should be checked by a doctor or dentist to rule out other causes.

Symptoms in older adults

• In older adults, leukoplakia is more likely to be linked to long-term smoking or alcohol use, and the risk of precancerous changes is slightly higher.
• Patches that bleed, hurt, grow, or do not heal need a quick medical review.

Causes

Main causes

• Smoking tobacco (cigarettes, cigars, or pipes)
• Chewing tobacco or using snuff
• Heavy alcohol use, especially together with smoking
• Chronic irritation from rough teeth, broken fillings, or ill-fitting dentures
• Infection with certain types of human papillomavirus (HPV), though this is less common

Risk factors

• Being male and over 40
• Long-term tobacco use
• Drinking more than the recommended limits of alcohol
• A diet low in fruit and vegetables
• Having a weakened immune system

When to see a doctor

See a doctor urgently if:

• A white or red patch in the mouth that bleeds, hurts, or grows quickly
• A sore or patch that does not heal within three weeks
• Difficulty or pain when swallowing, or a lump in the neck

Book a routine appointment if:

• Any white patch inside the mouth that lasts more than two weeks
• A rough area on your tongue or cheek that does not go away
• Changes in existing dentures or teeth that seem to rub against a patch

Diagnosis

A doctor or dentist will look inside your mouth, feel your neck, and ask about your smoking, alcohol, and any symptoms. If the patch looks suspicious, they will remove a small piece of tissue (a biopsy) to send to a laboratory for examination under a microscope.

Tests that may be done

• Careful visual and manual examination of your mouth and neck
• Biopsy – taking a small tissue sample under local anaesthetic to check for abnormal cells
• Sometimes a special light or dye is used to help identify areas that need closer inspection

What to expect at your appointment

A biopsy usually takes only a few minutes. You will have a local anaesthetic, so you should not feel pain, just a slight pinch or pressure. The area may feel sore for a few days. Results usually come back in about one week, and your doctor will discuss the findings and next steps with you.

Treatment

Treatment for leukoplakia depends on the size, location, and biopsy results. If the patch is harmless and has no abnormal cells, your doctor may simply keep it under regular review. If the biopsy shows early abnormal changes, the whole patch is usually removed to reduce the risk of cancer.

Self-care at home

• Stop smoking and avoid all forms of tobacco, including chewing tobacco and snuff
• Cut down on alcohol, or stop drinking if you can
• Ask your dentist to smooth rough teeth, fix broken fillings, or adjust dentures that rub
• Check your mouth regularly in a mirror and report any changes to your medical team

Medical treatments

In general, there is no specific cream or mouthwash that is routinely recommended for leukoplakia. The most reliable approach is close monitoring or surgical removal of the patch. Some clinics may use additional tests or treatments as part of clinical research. Always ask your care team about what is right for you.

When is surgery considered?

If the biopsy shows cells that are markedly abnormal, a doctor who specialises in oral medicine will usually remove the entire patch. This can be done with a simple surgical procedure, sometimes using a scalpel or a laser, under local or general anaesthetic.

Living with this condition

After a diagnosis of leukoplakia, you will need regular check-ups to make sure the patch has not come back or changed. Between appointments, look at your mouth in a mirror and tell your doctor or dentist if you notice any new spots, bleeding, or pain.

Lifestyle tips

• Join a stop-smoking programme if you smoke – this is the single most helpful step
• Limit alcohol to one drink per day if you drink, or ideally avoid it
• Attend all follow-up appointments, even if the patch is not bothering you
• Protect your lips from sun exposure to reduce the risk of other mouth changes

Diet and exercise

There is no special diet for leukoplakia, but eating plenty of fruit, vegetables, and whole grains helps keep your mouth healthy. If the patch is sensitive, avoid very hot, spicy, or acidic foods. Staying hydrated and keeping good mouth hygiene also help you feel more comfortable.

Mental health and emotional wellbeing

Waiting for tests or worrying about cancer is stressful. It is normal to feel anxious or low. Try to speak to your doctor, a counsellor, or someone you trust about what you are going through. You do not have to face this alone.

Prevention

Many cases of leukoplakia can be prevented by not using tobacco, limiting alcohol, and having regular dental check-ups. If you already have leukoplakia, stopping tobacco and reducing alcohol can help the patch heal and lower the chance of it becoming cancer.

Vaccines

The HPV vaccine protects against the types of HPV that can cause mouth and throat cancers. It is usually given to young people before they are exposed. Ask your health service whether you or your children are eligible.

Screening programmes

There is no UK-wide screening programme for leukoplakia. However, dentists routinely check for unusual patches in your mouth during every appointment, which is one important reason to keep up with regular dental visits.

Complications

If left untreated

• A small percentage of leukoplakia patches contain or develop abnormal cells that can turn into mouth cancer over time
• If mouth cancer develops, it can spread to the tongue, jaw, or lymph nodes in the neck
• Large patches may cause discomfort and make chewing, swallowing, or speaking less comfortable

Long-term outlook

The outlook for people with leukoplakia is generally very good. Only a small fraction of patches become cancer, and removing or monitoring them early lowers the risk even further. With regular check-ups and healthy lifestyle changes, most people can manage the condition without major problems.
