What Causes Recurrent Mouth Ulcers?

Frequent anger or emotional stress can easily lead to repeated outbreaks of mouth ulcers. To prevent their occurrence, one may take some heat-clearing medications or consume fruits that help reduce internal heat. For example, pears, dragon fruit, and apples are all fruits known for their heat-clearing properties. Drinking honeysuckle tea or chrysanthemum tea can also help clear heat and fire from the body, thus preventing mouth ulcers. People who are picky eaters or have unhealthy diets are more prone to various health issues. For instance, individuals with vitamin deficiencies are more likely to develop mouth ulcers. It is recommended that those who frequently suffer from mouth ulcers increase their intake of fruits and vegetables, avoid spicy foods, and drink plenty of water to help prevent recurrence.

Persistent non-healing mouth ulcers, especially in patients with anxiety disorders, can cause mental stress and depression. Prolonged pain can significantly affect quality of life. Chronic mouth ulcers may also lead to swelling of lymph nodes in the submandibular region or near the parotid gland, causing localized tenderness. Long-standing, severe ulcers that are slow to heal may result in scar formation or even local soft tissue defects in the oral cavity, commonly seen in the soft palate area.

Mouth ulcers can cause intense pain and a burning sensation at the affected site. In severe cases, they may interfere with eating and speaking, greatly affecting daily activities. They may also be accompanied by systemic symptoms such as bad breath, chronic pharyngitis, and constipation. We hope this information is helpful to you. Wishing you good health and a happy life!

Recurrent oral ulcers

Recurrent oral ulcers may indicate vitamin B deficiency or compromised immune function. Maintaining good oral hygiene is essential—particularly for individuals with iron or B-vitamin deficiencies, as their oral mucosa is more prone to injury and ulceration. According to Traditional Chinese Medicine (TCM), oral ulcers often result from yin deficiency of the lungs and kidneys, leading to ascending deficient fire and inflammation; treatment should therefore focus on nourishing yin, clearing heat, and guiding the fire back to its source. Individuals with recurrent oral ulcers are advised to seek medical evaluation at a hospital to confirm the underlying cause and receive targeted therapy.
