Canker Sores: Causes, Home Remedies, Risk Factors, and Diagnosis

What Are Canker Sores?

Canker sores, also known as aphthous ulcers, are shallow lesions that develop on the soft tissues inside the mouth or at the base of the gums. These sores are usually round or oval with a white or yellow centre surrounded by a red border. While small canker sores are the most common, major and herpetiform sores are more severe but less frequent. Symptoms often include pain, a burning sensation, and swelling around the sore.

Causes of Canker Sores

The exact causes of canker sores remain unclear, but several factors are known to trigger their development:

• Stress: Emotional stress can weaken the immune system, making it easier for canker sores to form.
• Nutrient Deficiencies: A lack of essential nutrients such as iron, vitamin B12, and folic acid can contribute to their appearance.
• Oral Injuries: Accidental bites, poorly fitting dental appliances, or vigorous brushing can damage the oral tissues, leading to canker sores.
• Food Sensitivities: Spicy, acidic, or salty foods can irritate the mouth and trigger sores.
• Allergies: Allergic reactions to certain foods or dental products may also cause canker sores.

Risk Factors Associated with Canker Sores

Several factors can increase your risk of developing canker sores:

• Genetics: A family history of canker sores may predispose you to this condition.
• Hormonal Changes: Women often experience canker sores during menstruation, pregnancy, or menopause.
• Health Conditions: Chronic diseases such as celiac disease, Crohn’s disease, or an impaired immune system can elevate the likelihood of recurring sores.

When to See a Doctor

While most canker sores heal without intervention, certain signs warrant a visit to a healthcare provider:

• Persistent sores lasting more than two weeks.
• Sores that are unusually large or spreading.
• High fever or difficulty swallowing.
• Recurring sores that disrupt daily life.

Diagnosis of Canker Sores

Diagnosing canker sores usually involves a simple physical examination of the mouth. If sores are persistent or severe, your doctor may recommend:

• Blood Tests: To identify deficiencies or rule out systemic conditions.
• Biopsy: Rarely, a tissue sample may be needed to rule out other conditions.
• Allergy Tests: To detect sensitivities that may trigger sores.
