Reasons for Recurrent Oral Ulcers

The causes of recurrent oral ulcers are diverse and complex, mainly including the following points: 1. **Genetic factors**: Individuals with a family history of oral ulcers have an increased risk of developing the condition. 2. **Immune dysfunction**: Emotional states such as high mental stress or tension may lead to immune system disturbances, triggering recurrent oral ulcers. 3. **Nutritional deficiencies**: Deficiencies in B vitamins, vitamin C, and trace elements such as iron and zinc are important contributing factors to recurrent oral ulcers. 4. **Local irritation**: Long-term mucosal irritation caused by residual tooth roots, broken crowns, or ill-fitting dentures in the oral cavity can also easily lead to recurring ulcers. 5. **Bacterial or viral infections**: Infections such as streptococcus bacteria or herpes viruses may be responsible for recurrent oral ulcers in some cases. Therefore, treatment should be comprehensive and targeted. If you have any concerns, please consult a relevant healthcare professional.
