2. Common Benign Oral Lesions
Benign oral lesions are non-cancerous growths or abnormalities in the mouth. While they are generally harmless, they can cause discomfort or concern and may require management to alleviate symptoms or prevent complications.
2.1. Aphthous Ulcers (Canker Sores)
Aphthous ulcers, commonly known as canker sores, are small, painful ulcers that appear inside the mouth. They are characterized by a white or yellowish center surrounded by a red halo.
- Symptoms: Pain, sensitivity to touch and certain foods, and difficulty speaking or eating.
- Causes: The exact cause is unknown, but factors like stress, hormonal changes, immune system dysfunction, and minor injuries may trigger them.
- Treatment: Most canker sores heal on their own within one to two weeks. Over-the-counter pain relievers, topical corticosteroids, and antimicrobial mouthwashes can help manage symptoms. In severe cases, prescription medications may be necessary.
2.2. Cold Sores (Herpes Simplex Virus)
Cold sores, also known as fever blisters, are caused by the herpes simplex virus type 1 (HSV-1). They typically appear on or around the lips as small, fluid-filled blisters.
- Symptoms: Tingling or burning sensation, followed by the appearance of blisters that eventually crust over.
- Causes: HSV-1 is highly contagious and can be transmitted through direct contact, such as kissing or sharing utensils.
- Treatment: Antiviral medications, available as creams or oral tablets, can help shorten the duration and severity of outbreaks. Over-the-counter remedies like cold sore patches can also provide relief.
2.3. Oral Thrush (Candidiasis)
Oral thrush is a fungal infection caused by an overgrowth of Candida yeast in the mouth. It appears as white, curd-like patches on the tongue, inner cheeks, and other oral tissues.
- Symptoms: White patches, redness, soreness, and a cotton-like sensation in the mouth.
- Causes: Factors like weakened immune system, antibiotic use, diabetes, and dentures can contribute to Candida overgrowth.
- Treatment: Antifungal medications, such as nystatin mouthwash or clotrimazole lozenges, are commonly prescribed to treat oral thrush.
2.4. Fordyce Spots
Fordyce spots are small, yellowish-white bumps that appear on the lips or inner cheeks. They are enlarged sebaceous glands and are generally harmless.
- Symptoms: Small, painless bumps that may be slightly raised.
- Causes: Fordyce spots are a normal anatomical variation and are not caused by any underlying condition.
- Treatment: Fordyce spots do not require treatment as they are benign and asymptomatic.
2.5. Geographic Tongue
Geographic tongue is a condition characterized by irregular, map-like patches on the surface of the tongue. These patches are caused by the loss of filiform papillae and can change in size, shape, and location over time.
- Symptoms: Irregular patches on the tongue, sensitivity to certain foods, and mild discomfort.
- Causes: The exact cause is unknown, but factors like genetics, stress, and allergies may play a role.

Precancerous oral lesions, also known as potentially malignant disorders, are conditions that have a higher risk of developing into oral cancer. Early identification and management of these lesions are crucial for preventing the progression to malignancy.
3.1. Leukoplakia
Leukoplakia is a white patch or plaque that develops on the oral mucosa and cannot be scraped off or attributed to any other identifiable cause. It is considered a precancerous lesion, with a risk of transforming into oral squamous cell carcinoma.
- Symptoms: White patch or plaque, which may be smooth, wrinkled, or thickened.
- Causes: Tobacco use, alcohol consumption, chronic irritation, and human papillomavirus (HPV) infection are common risk factors.
- Diagnosis: A biopsy is necessary to determine the presence and degree of dysplasia (abnormal cell growth) within the lesion.
- Management: Treatment options include surgical excision, laser ablation, cryotherapy, and topical medications. Regular follow-up is essential to monitor for any signs of malignant transformation.
3.2. Erythroplakia
Erythroplakia is a red patch or plaque on the oral mucosa that cannot be attributed to any other identifiable cause. It is less common than leukoplakia but carries a higher risk of malignant transformation.
- Symptoms: Red patch or plaque, which may be smooth, velvety, or slightly raised.
- Causes: Similar to leukoplakia, risk factors include tobacco use, alcohol consumption, and HPV infection.
- Diagnosis: A biopsy is required to evaluate the lesion and rule out malignancy.
- Management: Treatment typically involves surgical excision to remove the lesion and prevent cancer development.
3.3. Oral Submucous Fibrosis
Oral submucous fibrosis (OSMF) is a chronic, progressive condition characterized by fibrosis (scarring) of the oral tissues. It is commonly associated with betel quid chewing and is considered a precancerous condition.
- Symptoms: Stiffness of the oral mucosa, difficulty opening the mouth, burning sensation, and blanching of the oral tissues.
- Causes: Betel quid chewing is the primary cause, but genetic factors and nutritional deficiencies may also contribute.
- Diagnosis: Clinical examination and biopsy are used to diagnose OSMF and assess the degree of fibrosis.
- Management: Treatment focuses on managing symptoms, preventing disease progression, and monitoring for malignant transformation. Options include corticosteroids, physiotherapy, and surgical release of fibrotic bands.
3.4. Actinic Cheilitis
Actinic cheilitis is a precancerous condition that affects the lips, primarily the lower lip. It is caused by chronic exposure to sunlight and is characterized by dryness, scaling, and loss of the vermilion border.
- Symptoms: Dry, scaly lips, thinning of the vermilion border, and development of crusts or ulcers.
- Causes: Chronic sun exposure is the primary cause.
- Diagnosis: Clinical examination and biopsy are used to diagnose actinic cheilitis and rule out squamous cell carcinoma.
- Management: Treatment includes sun protection measures, topical medications, cryotherapy, and surgical excision.
