What Causes Recurrent Mouth Ulcers?

In daily life, people frequently encounter various oral diseases, among which recurrent aphthous ulcers (canker sores) are the most common. Many individuals develop ulcers on the tongue and oral mucosa. These ulcers are typically extremely painful and often persist for extended periods, making treatment challenging—hence their high prevalence.

What Causes Recurrent Oral Ulcers?

Recurrent oral ulcers are commonly associated with factors such as nutritional imbalances, genetic predisposition, psychological stress, compromised immune function, and gastrointestinal disorders. In most cases, oral ulcers result from an unbalanced diet—for instance, excessive consumption of meat coupled with insufficient intake of vegetables, leading to deficiencies in essential vitamins and minerals.

Oral ulcers are a common oral condition with a known genetic component. Currently, many individuals develop ulcers due to significant psychological and social stress. A weakened immune system reduces the body’s resistance; even a minor injury inside the mouth can become infected easily, thereby forming an ulcerative lesion.

In summary, preventive measures include regular outdoor physical activity, a light and balanced diet, adequate vitamin supplementation, and effective stress management. When necessary, topical treatments such as oral ulcer patches and systemic medications may be used. We hope this information proves helpful to you.
