Aphthous stomatitis refers to the repeated development of small ulcers in the mouth, typically affecting the inner lips, cheeks, tongue, or soft palate. These ulcers are shallow, round or oval sores with a white or yellow center and a red border. They are not contagious and are one of the most common oral mucosal conditions. The exact cause is not fully understood, but it is believed to involve an immune-related response. Contributing factors may include stress, minor trauma, hormonal changes, or nutritional deficiencies such as low levels of vitamin B12, iron, or folate. Certain foods or sensitivities may also trigger episodes in some individuals. Over time, these ulcers tend to recur in cycles, with periods of healing followed by new outbreaks. If this process continues, episodes may vary in frequency and severity. While most cases are mild and self-limiting, more severe forms can involve larger or more numerous ulcers that may take longer to heal.

Frequently Asked Questions
Are aphthous ulcers contagious?
No, aphthous ulcers are not contagious. In many cases, they are related to internal factors such as immune response, stress, or minor trauma rather than infection. This means they cannot be spread through contact, sharing utensils, or close interaction.
How long do aphthous ulcers last?
Most aphthous ulcers heal within 7 to 14 days. In many cases, smaller ulcers resolve more quickly, while larger ones may take longer. The discomfort usually decreases as healing progresses. If ulcers persist beyond two weeks or occur frequently, evaluation may be recommended.
What triggers aphthous stomatitis?
Triggers can vary from person to person. In many cases, factors such as stress, minor injury to the mouth, or certain foods may contribute. Nutritional deficiencies and hormonal changes may also play a role. Identifying individual triggers can help reduce recurrence.
What is the most common treatment for aphthous ulcers?
The most common treatment involves topical medications, such as corticosteroid gels or protective pastes, to reduce inflammation and discomfort. In many cases, these treatments help ulcers heal more comfortably. Supportive care is often sufficient for mild cases.
When should I be concerned about recurring ulcers?
Frequent, large, or persistent ulcers should be evaluated by a dental or medical professional. In many cases, this helps identify underlying causes such as nutritional deficiencies or other conditions. Early evaluation supports appropriate management and symptom control.
