What are the symptoms of aphtha?
Aphthous ulcers, also known as canker sores, are a common disease of the oral mucosa. Although canker sores usually do not pose a serious health threat, the pain and discomfort they cause can be bothersome. Knowing the symptoms of canker sores can help you identify them promptly and take appropriate treatment. Here’s a detailed look at the symptoms of canker sores.
1. Common symptoms of aphthous ulcers

Symptoms of mouth sores vary from person to person, but usually include the following:
| Symptoms | Description |
|---|---|
| pain | The most obvious symptom of canker sores is pain, especially when eating, talking, or touching the sore area. |
| ulcer appearance | Ulcers are usually round or oval in shape with clear edges, a white or yellow center, and a surrounding area of red inflammation. |
| Quantity and size | Mouth sores can be single or multiple and can range in size from a few millimeters to a centimeter. |
| duration | Most canker sores will heal on their own within 1-2 weeks, but severe or recurring ulcers may take longer. |
2. Classification of aphthous ulcers
Depending on the severity and characteristics of the ulcer, canker sores can be divided into the following categories:
| Type | Features |
|---|---|
| Mild aphtha | Most commonly, ulcers are small (less than 1 cm in diameter), less numerous, and heal quickly. |
| Severe aphtha | Ulcers are larger (more than 1 cm in diameter), numerous, heal slowly, and may leave scars. |
| Herpetiform aphtha | The ulcers are numerous (up to dozens) but small in size, similar to herpes, and do not leave scars after healing. |
3. Symptoms associated with aphthous ulcers
In addition to the symptoms of ulcers themselves, canker sores may also be accompanied by the following symptoms:
| accompanying symptoms | Description |
|---|---|
| swollen lymph nodes | Some patients may develop swollen lymph nodes in the neck or jaw. |
| Fever | Patients with severe or recurrent aphthous ulcers may have low-grade fever. |
| General malaise | A small number of patients may experience fatigue or loss of appetite. |
4. Causes of aphthous ulcers
Understanding the triggers of canker sores can help prevent their occurrence. Here are common triggers:
| inducement | Description |
|---|---|
| Trauma | Physical damage to the oral mucosa (such as bites, toothbrush scratches) may lead to aphthous ulcers. |
| diet | Spicy, acidic or hard foods may irritate mucous membranes and cause mouth sores. |
| pressure | Stress or excessive stress can increase the risk of mouth sores. |
| Decreased immunity | When immunity is low, ulcers are more likely to occur in the oral mucosa. |
5. How to relieve the symptoms of canker sores
Although canker sores usually heal on their own, the following methods can relieve symptoms:
| method | Description |
|---|---|
| topical medications | Use canker sore patches or ointments containing anti-inflammatory and analgesic ingredients. |
| Rinse mouth | Rinse your mouth with warm salt water or antibacterial mouthwash to reduce the risk of bacterial infection. |
| diet modification | Avoid spicy and acidic foods and eat more foods rich in vitamins B and C. |
| Maintain oral hygiene | Use a soft-bristled toothbrush when brushing to avoid further irritating the ulcer. |
6. When Do You Need Medical Treatment?
Most canker sores require no special treatment, but timely medical attention is recommended if:
| situation | Description |
|---|---|
| Ulcer that does not heal | Does not heal for more than two weeks, or relapses. |
| Large ulcer area | More than 1 cm in diameter, or in large quantities. |
| accompanied by severe symptoms | Such as high fever, general fatigue, etc. |
Although mouth sores are common, they can be better prevented and managed by understanding their symptoms and triggers. If symptoms are severe or recurring, it is recommended to consult a doctor for more professional treatment advice.
