Introduction
The causes of oral ulcers are diverse and include infection, allergic reactions, excessive internal heat (“shang huo”), malocclusion, and deficiencies in B-complex vitamins. Among these, infection and vitamin deficiency are the most common etiologies. Since the underlying causes of oral ulcers vary, treatment approaches must be tailored accordingly. Additionally, environmental factors—such as sleep deprivation, emotional anxiety, and depression—can contribute to the development of oral ulcers.
Aphthous ulcers (canker sores) are a relatively common oral condition encountered in daily life. Some patients dismiss their occurrence and fail to seek timely intervention, leading to progressive worsening—leaving them puzzled about the underlying cause. So, what causes aphthous ulcers?
Causes of Aphthous Ulcers
Aphthous ulcers have multiple potential causes, including infection, allergic reactions, “excess internal heat” (a traditional Chinese medicine concept), malocclusion (abnormal tooth alignment or bite), and deficiencies in B-complex vitamins. Among these, infection and vitamin deficiency are the most frequent etiologies. Since treatment strategies vary depending on the underlying cause, accurate diagnosis is essential. Additionally, environmental factors such as sleep deprivation, anxiety, and depression may contribute to ulcer development.
Following onset, aphthous ulcers often cause significant pain. Topical medications that promote ulcer healing are commonly used. Oral ulcer powders, various oral films, and adhesive patches also effectively support healing. For ulcers caused by infection, local application of oral ulcer powder or an oral ulcer spray is recommended. In cases attributable to vitamin B2 (riboflavin) deficiency, supplementation with oral multivitamin tablets or vitamin B2 tablets is advised.
Dietary considerations are critical during recovery: avoid spicy, irritating, pickled, sharp, or hard foods. Instead, opt for soft, tender, and nutrient-rich meals to facilitate healing. Consuming fresh vegetables and fruits helps replenish vitamin C and B-complex vitamins—both beneficial for ulcer resolution. Furthermore, adequate rest, emotional regulation, quality sleep, positive mood, and moderate physical activity all contribute significantly to recovery. We hope this article proves helpful to you!
