1. What Are Canker Sores?
Canker sores, or aphthous ulcers, are small, shallow lesions that develop on the soft tissues inside your mouth. These can appear on the inside of your cheeks, lips, on or under your tongue, at the base of your gums, or on your soft palate. They are characterized by a white or yellow center surrounded by a red border. Unlike cold sores, canker sores are not contagious and do not appear on the surface of the lips. They can, however, be quite painful, making eating, drinking, and talking uncomfortable. Canker sores can be a common occurrence and can affect individuals of all ages.
2. Identifying Symptoms of Canker Sores
Recognizing the symptoms of canker sores is essential for proper management. The most common signs include:
- Appearance: Typically round or oval with a white or yellow center and a red border.
- Location: Inside the mouth, such as on or under the tongue, inside the cheeks or lips, at the base of the gums, or on the soft palate.
- Initial Sensation: A tingling or burning feeling one or two days before the sores appear.
- Pain: Significant pain, especially when eating, drinking, or talking.
It’s important to differentiate between the types of canker sores, as they can vary in severity and duration. The main types include minor, major, and herpetiform canker sores.
2.1 Minor Canker Sores
Minor canker sores are the most prevalent type and possess distinct characteristics:
- Size: Usually small.
- Shape: Oval-shaped with a red edge.
- Healing: They generally heal without scarring within one to two weeks.
These sores are typically more of a nuisance than a major health concern, but they can still cause discomfort.
2.2 Major Canker Sores
Major canker sores are less common but more severe. Their characteristics include:
- Size and Depth: Larger and deeper than minor canker sores.
- Shape: Usually round with defined borders, though very large sores may have irregular edges.
- Pain: Often extremely painful.
- Healing: Can take up to six weeks to heal and may leave extensive scarring.
Individuals experiencing major canker sores may find it challenging to perform everyday activities like eating and speaking.
2.3 Herpetiform Canker Sores
Herpetiform canker sores are uncommon and have unique features:
- Size: Pinpoint size.
- Occurrence: Often appear in clusters of 10 to 100 sores, which may merge into one large ulcer.
- Edges: Irregular edges.
- Healing: Heal without scarring in one to two weeks.
Despite their name, herpetiform canker sores are not caused by the herpes virus.
