Mouth sores are a common condition that can affect people of all ages. While most mouth sores are harmless and heal on their own, some can signal more serious health issues. The treatment for mouth sores depends largely on their type, as various conditions can cause these painful lesions.
Mouth Sores: Causes, Types, and Treatments
What Are Mouth Sores?
Mouth sores are painful lesions that develop on the soft tissues inside your mouth. These sores can appear on your lips, gums, tongue, the inside of your cheeks, the floor of your mouth, or even the roof of your mouth. While they can be distressing, mouth sores usually heal within a few weeks, though some types may require medical attention.
Types of Mouth Sores
Mouth sores can be categorized into several types, each caused by different factors. The most common types of mouth sores include:
Canker Sores: Also known as mouth ulcers, canker sores are typically round or oval and appear white, yellow, or gray with a red border. They are not contagious and usually heal within 10 to 14 days.
Cold Sores: Also referred to as fever blisters, cold sores are caused by the herpes simplex virus (HSV). These sores are contagious and can spread through direct contact like kissing or sharing food and drinks.
Gingivostomatitis: This condition, which can be caused by either viral or bacterial infections, is marked by painful sores in the mouth, usually affecting the gums or the inner cheeks. It is most commonly seen in children.
Thrush: Also known as oral candidiasis, thrush is a fungal infection in the mouth. It results in white, creamy lesions on the tongue, gums, and the inside of the cheeks. While it isn’t typically contagious, thrush can occur in people with weakened immune systems.
Oral Lichen Planus: This chronic inflammatory disorder leads to lacy, raised lesions in the mouth, often on the gums, tongue, and inside the cheeks. The cause of oral lichen planus remains unclear but it is often associated with other autoimmune conditions.
Leukoplakia: This condition involves thick, white patches in the mouth. It is often linked to tobacco use. While leukoplakia usually resolves on its own, persistent or severe cases can sometimes be a sign of oral cancer.
Oral Cancer: Mouth cancer can present itself as sores or lesions that do not heal over time. These types of sores may appear red, white, or ulcerated and should be evaluated by a healthcare professional immediately.

Who Is Affected by Mouth Sores?
Anyone can experience mouth sores, but the likelihood of developing certain types may vary by age. For instance, conditions like thrush and gingivostomatitis are more common in children, while leukoplakia and oral lichen planus are more frequently seen in older adults.
Cold sores and canker sores are among the most prevalent oral lesions. Around 20% of individuals will get canker sores at some point in their lives, while more than half of people are infected with the herpes simplex virus that causes cold sores, although only 20-40% of these individuals will actually develop the lesions.
Symptoms of Mouth Sores
