Overview: Understanding Canker Sores
Canker sores are small, shallow ulcers that appear in the soft tissues of your mouth or at the base of your gums. Unlike cold sores, they do not occur on the surface of your lips and aren’t caused by viruses. Canker sores often make eating, drinking, and even talking uncomfortable, although they generally resolve on their own within one to two weeks.
Symptoms and Types of Canker Sores
- Minor canker sores: Small, round or oval, white or yellow ulcers with a red border; usually heal within 2 weeks without scarring.
- Major canker sores: Larger, deeper ulcers; may last up to 6 weeks and potentially leave scars.
- Herpetiform canker sores: Tiny, multiple clusters that may merge into one large ulcer; usually heal in about 2 weeks.
Typical symptoms include burning or tingling sensations before sores appear, pain during eating or talking, and visible lesions inside the mouth.
What Causes Canker Sores?
The exact cause of canker sores remains unclear, but several triggers and risk factors are recognized:
- Minor injuries to oral tissues (e.g., biting your cheek, dental work)
- Food sensitivities (e.g., acidic or spicy foods)
- Vitamin deficiencies (e.g., B12, folate, iron, zinc)
- Hormonal changes (e.g., menstruation)
- Stress and emotional disturbances
- Underlying medical conditions (e.g., autoimmune disorders, gluten sensitivity)
How Long Do Canker Sores Last?
Most canker sores heal without treatment within one to two weeks for minor sores; major or herpetiform types may take longer. If healing is delayed or symptoms are severe, consult a healthcare provider.

- Stay hydrated for mucosal health.
- Practice stress management: Yoga, meditation, or deep breathing can reduce frequency in stress-related outbreaks.
When to Seek Medical Help
