Common Oral Lesions: What They Mean Clinically
Mouth lesions are common, but not all are the same. Some are harmless and heal on their own, while others may need professional evaluation. Understanding the difference is important for early diagnosis and patient safety.
▪️Herpes (Cold Sores)
Small, fluid-filled blisters on the lips caused by a virus (HSV-1). Often painful and contagious during the active stage.
▪️Aphthous Ulcers (Canker Sores)
Small, round ulcers inside the mouth with a red border. Not contagious. Commonly linked to stress, minor injury, or nutritional deficiencies.
▪️Mucocele
A soft, painless swelling, usually on the lower lip. Caused by blockage or trauma to a salivary gland.
▪️Traumatic Ulcer
Occurs due to irritation from biting, sharp teeth, or dental appliances. Typically heals within 1–2 weeks once the cause is removed.
▪️Angular Cheilitis
Cracks or soreness at the corners of the mouth. Often related to dryness, fungal infection, or nutritional issues.
▪️Leukoplakia
A white patch that cannot be wiped off. Usually painless, but important because it can be a precancerous lesion and should always be evaluated.
When to be concerned:
• Any lesion lasting more than 2 weeks
• Non-healing ulcers
• Persistent white or red patches
• Unexplained pain or bleeding
Early evaluation is key. When in doubt, a clinical examination is essential.
