Introduction
The occurrence of oral ulcers is also associated with the patient’s immune function. When immunity declines, the oral cavity becomes more susceptible to invasion by viruses and bacteria. Moreover, if the immune system fails to fully prevent this condition, oral ulcers may develop. Therefore, patients should pay attention to their daily nutritional intake and promptly address any immune-related issues to help prevent disease onset.
Recurrent aphthous ulcers (commonly known as canker sores) are a condition many people have experienced. However, some patients remain unaware of the underlying causes—often developing the condition unexpectedly. So, what causes oral ulcers?
Causes of Oral Ulcers
The development of oral ulcers is closely linked to an individual’s immune status. When immunity declines, the oral mucosa becomes more susceptible to invasion by viruses and bacteria. Moreover, even a normally functioning immune system may fail to fully prevent this condition, thereby triggering ulcer formation. Therefore, patients should pay close attention to their daily nutritional intake and promptly address any signs of compromised immunity to help prevent disease onset. Dietary habits play a direct and significant role in ulcer development: regularly consuming heavily seasoned or spicy foods can excessively irritate the oral mucosa and precipitate ulcers. In fact, dietary irritation is considered the most common cause of oral ulcers. Alternatively, if an individual develops stomatitis despite having no apparent oral trauma, it may stem from long-term consumption of a monotonous diet. Such diets often lack comprehensive nutrition, leading to chronic deficiencies—particularly in essential vitamins—which predispose individuals to oral inflammation and ulceration.
Key considerations for patients with oral ulcers: • Maintain meticulous oral hygiene—brush teeth thoroughly twice daily (morning and evening) to inhibit bacterial proliferation in the mouth. • Avoid spicy, acidic, or otherwise irritating foods that may aggravate existing ulcers. • Adopt a positive, optimistic mindset—even minor illnesses benefit from psychological resilience—and ensure adequate, restorative sleep to support natural healing processes.
At this time, patients should strive to maintain emotional calmness and optimism, avoiding stress, anxiety, or impatience. Establishing regular sleep-wake patterns—including early bedtimes and early risings—and preventing excessive fatigue are also crucial. We hope this information proves helpful to you!
