What is leukoplakia?
Leukoplakia or oral leukoplakia is a disorder that causes thicker, white patches to grow on the tongue, gums, and inside of the cheek, which cannot be scraped off easily. Although the appearance of the sores varies, they are generally white or gray, thick, and somewhat elevated with a firm surface.
Leukoplakia is usually painless; however, some individuals report sensitivity in the affected region. The patches frequently appear gradually over weeks or months. They might be smooth or somewhat rough, flat or elevated.
It is believed that persistent irritation may be the source of the disease; however, this is not always the case. Removing the source of irritation may alleviate the problem, but surgical removal of the sores may be required in certain situations.
Usually, leukoplakia is harmless and is just cosmetic. However, leukoplakia can occasionally be a precursor to oral cancer and an early indication of malignancy. To be safe, any oral lesions should be addressed carefully as soon as they appear until they can be proven benign.
What is the main cause of leukoplakia?
The following are some of the most common causes of leukoplakia:
What are the types of leukoplakia?
Leukoplakia is classified into various types that include:
- Homogenous leukoplakia
- Nonhomogenous leukoplakia
- An uneven blend of white and red lesions.
- If the red areas are not treated, they are more likely to become precancerous or cancerous.
- Proliferative verrucous leukoplakia
- Hairy leukoplakia
- The lesions in hairy leukoplakia are folded or ridged, with thin hairlike filaments sprouting from the lesion.
- Results when the immune system is compromised following Epstein–Barr virus and HIV attacks.
What are the signs and symptoms of leukoplakia?
Symptoms of leukoplakia may be similar to those of other illnesses, which may include the following:
- The major sign of leukoplakia is elevated or hardened white spots in the mouth, particularly within the cheeks or on the tongue.
- These patches or lesions are generally harmless, and people are often unaware of their presence until they are apparent.
- There may also be red scaly patches or a combination of hard red and white raised pimples in the mouth.
- These white or red and white patches are distinguished by their rough look and the fact that they do not dissolve when the mouth is cleaned or scraped with an appropriate dental instrument.
How is leukoplakia diagnosed?
Your healthcare provider conducts an oral examination and may attempt to remove the white areas. If the white patches can be wiped off easily, then it is probably not leukoplakia. A detailed medical history to identify potential risk factors, such as smoking or chewing tobacco, will be noted.
Sometimes, it may not be easy to know if the spots are leukoplakia or another condition, such as oral thrush, just by looking at them. To establish what is causing the patches, a doctor will need to conduct some tests.
You may be screened for cancer, and the doctor might look for early warning symptoms and suggest a biopsy.
A biopsy removes tissue from the body to test for diseases like cancer.
Cancer screening for people with leukoplakia may involve the following tests:
- Oral brush biopsy
- A small spinning brush is used to remove some cells from the outer surface of the lesion.
- The collected cells sample are further screened for malignancy
- Excisional biopsy
- Surgical excision of some tissue from the leukoplakia lesion is performed and tested for malignancy.
- Excisional biopsy is a more reliable test to detect cancer than oral brush biopsy.
If the excisional biopsy report comes positive for cancer, your doctor may refer you to a specialist for further treatment. In some instances, the leukoplakia patch may be so small that it may be eradicated with excisional biopsy. That implies no further active treatment may be necessary other than continuous observation.

How do you get rid of leukoplakia?
Leukoplakia is best managed when diagnosed and treated in the early stages. Mild leukoplakia does not require active treatment, and it subsides independently. However, if leukoplakia necessitates treatment, the first step should be eliminating the cause or source of irritation.
- If leukoplakia is caused by a rough tooth or an uneven surface on a denture or filling, the tooth will be smoothed, and dental equipment will be corrected.
- If smoking is the cause of your leukoplakia, you will be urged to reduce or quit smoking or use other tobacco products.
Leukoplakia usually is benign, and lesions resolve after a few weeks or months of removing the source of irritation. If removing the cause of irritation does not reduce the leukoplakia, the lesion may need to be surgically removed. Either your conventional dentist or an oral surgeon can remove the lesion.
Is leukoplakia cancerous?
Not all cases of leukoplakia turn into cancer; however, oral leukoplakia may be a premalignant condition that can turn cancerous and is most typically found among smokers.
People with oral leukoplakia are more likely to acquire oral cancer than those with normal oral mucosa. Leukoplakia is one of the most prevalent oral potentially malignant diseases, with a global incidence of 1.5 to 2.6 percent.
This premalignant condition can progress to oral cancer, especially squamous cell carcinoma, with transformation rates ranging from 0.1 to 17.5 percent. Because of the diversity in the transition to malignancy, early detection, treatment, and monitoring are crucial.
When oral leukoplakia is identified, the primary objective is to prevent it from progressing to invasive cancer using therapeutic approaches, such as classic knife excision, cryotherapy, and carbon dioxide laser therapy.
How can you prevent leukoplakia?
Prevention is the best treatment for leukoplakia. The following suggestions can assist you in keeping these discolored lesions at bay:
- Stop smoking and using tobacco products.
- Consume alcohol in moderation.
- Regular visits to the dentist are recommended two times a year.

Human Immunodeficiency Virus (HIV)HIV (human immunodeficiency virus) infection left untreated causes AIDS (acquired immunodeficiency syndrome). The human immunodeficiency virus (HIV) is a type of virus called a retrovirus, which can infect humans when it comes in contact with tissues that line the vagina, anal area, mouth, or eyes, or through a break in the skin. HIV infection is generally a slowly progressive disease in which the virus is present throughout the body at all stages of the disease. Three stages of HIV infection have been described. The initial stage of infection (primary infection), which occurs within weeks of acquiring the virus, often is characterized by the flu- or mono-like illness that generally resolves within weeks. The stage of chronic asymptomatic infection (meaning a long duration of infection without symptoms) lasts an average of eight to 10 years without treatment. The stage of symptomatic infection, in which the body's immune (or defense) system has been suppressed and complications have developed, is called the acquired immunodeficiency syndrome (AIDS). The symptoms are caused by the complications of AIDS, which include one or more unusual infections or cancers, severe loss of weight, and intellectual deterioration (called dementia). When HIV grows (that is, by reproducing itself), it acquires the ability to change (mutate) its own structure. These mutations enable the virus to become resistant to previously effective drug therapy. The goals of drug therapy are to prevent damage to the immune system by the HIV virus and to halt or delay the progress of the infection to symptomatic disease. Therapy for HIV includes combinations of drugs that decrease the growth of the virus to such an extent that the treatment prevents or markedly delays the development of viral resistance to the drugs. The best combination of drugs for HIV are those that effectively suppress viral replication in the blood and also are well tolerated and simple to take so that people can take the medications consistently without missing doses.
