What Are Canker Sores?

Canker sores, medically known as aphthous ulcers, are small, painful lesions that develop in the mouth, particularly on the soft tissues such as the inside of the cheeks, gums, and tongue. Unlike cold sores, which are caused by the herpes simplex virus, canker sores are not caused by a virus and do not occur on the surface of the lips.

These sores can vary in size and typically appear as round or oval with a white or yellowish center and a red halo. Canker sores can be quite uncomfortable, making it difficult to eat, speak, or even swallow.

Types of Canker Sores

• Minor Canker Sores: These are the most common type, usually measuring less than 1 cm and healing within a week or two.
• Major Canker Sores: Larger and deeper than minor sores, these can take several weeks to heal and may leave scars.
• Herpetiform Canker Sores: These are rare and appear as clusters of small sores, often resembling cold sores.

Causes of Canker Sores

The exact cause of canker sores remains unclear, but several factors may contribute to their development, including:

• Stress or hormonal changes
• Food sensitivities (such as citrus fruits and nuts)
• Injury to the mouth (such as biting the cheek or aggressive brushing)
• Underlying health conditions (like celiac disease or nutritional deficiencies)
• Allergies to certain ingredients in toothpaste or mouthwash

Are Canker Sores Contagious?

The short answer is no, canker sores are not contagious. They cannot be spread through direct contact with an affected person, nor can they be transmitted via shared utensils, kisses, or other forms of close contact.

Understanding why canker sores are not contagious relies on recognizing that their development is often linked to individual factors, such as genetics, immune system response, and environmental triggers, rather than a contagious pathogen. This sets them apart from conditions like cold sores, which are caused by a virus and can easily spread from one person to another.

Myths About Canker Sores

• Myth 1: Canker sores are the same as cold sores.
• Myth 2: You can catch canker sores from someone else.
• Myth 3: Canker sores are caused by poor oral hygiene.

Symptoms of Canker Sores

The primary symptom of canker sores is the presence of painful ulcers in the mouth. Other associated symptoms may include:

• A burning or tingling sensation prior to the appearance of the sore
• Difficulty eating, drinking, or speaking
• Swollen lymph nodes in some cases

Treatment Options for Canker Sores

While canker sores typically heal on their own within one to two weeks, various treatment options can help alleviate discomfort and promote healing:

• Over-the-Counter Medications: Pain relief products such as topical anesthetics can help numb the area.
• Prescription Medications: In severe cases, a doctor may prescribe corticosteroids to reduce inflammation.
• Home Remedies: Rinsing with salt water or baking soda can provide temporary relief.

Preventing Canker Sores

While it may not be possible to prevent canker sores entirely, certain strategies may help reduce their occurrence:

• Avoiding trigger foods that may cause irritation
• Managing stress through relaxation techniques
• Maintaining good oral hygiene
• Using a soft-bristled toothbrush

When to See a Doctor

If canker sores are particularly large, painful, or persistent, or if they are accompanied by other symptoms like fever, it is advisable to consult a healthcare professional. A doctor can help rule out other conditions and provide appropriate treatment options.
