Aphthous ulcers, commonly known as canker sores, are small, painful lesions that can appear inside the mouth. They can disrupt eating, talking, and even smiling. A common question people have when they develop these sores is: How Long Do Aphthous Ulcers Last? Understanding the typical duration, as well as the factors that can influence healing time, can help you manage the discomfort and know when to seek professional help.
Decoding the Lifespan of a Canker Sore
How Long Do Aphthous Ulcers Last? Generally, aphthous ulcers last for about 1 to 2 weeks. The specific duration can depend on the type of ulcer you have. There are three main types of canker sores, each with varying sizes and healing times: Minor, Major, and Herpetiform. Minor aphthous ulcers are the most common and usually heal within 1 to 2 weeks without scarring. These are typically small, less than 1 cm in diameter, and oval-shaped with a red border.
Major aphthous ulcers, on the other hand, are larger, deeper, and more painful. These can take several weeks, sometimes even a month or more, to heal completely. Major ulcers are often irregular in shape and larger than 1 cm. They are more likely to leave scarring after they heal. Herpetiform ulcers are characterized by clusters of very small sores. While individually tiny, they can merge to form larger, irregular ulcers. These usually heal within 1 to 2 weeks, similar to minor ulcers. Here’s a quick comparison:
| Type of Ulcer | Size | Healing Time | Scarring |
|---|---|---|---|
| Minor | < 1 cm | 1-2 weeks | Rare |
| Major | > 1 cm | 2-4+ weeks | Possible |
| Herpetiform | Tiny, clustered | 1-2 weeks | Rare |
Several factors can influence how long an aphthous ulcer lasts. These include the overall health of the individual, the presence of any underlying medical conditions, nutritional deficiencies (such as vitamin B12, iron, or folate), stress levels, and even hormonal changes. Irritation from braces, dentures, or sharp teeth can also prolong healing. Certain foods, like acidic fruits, spicy dishes, or hard-crusted bread, can irritate the ulcer and delay healing. Avoid using toothpastes containing sodium lauryl sulfate, as they can trigger or worsen canker sores. Maintaining good oral hygiene, managing stress, and eating a balanced diet are essential to speed up the healing process.
