Why does oral cavity grow oral ulcer

Oral ulcers are usually related to genetic factors, immune factors, psychological factors, nutritional deficiencies, local stimulation factors, systemic disease factors and other factors. 1. Genetic factors If there is a history of oral ulcers in the family, the probability of individual occurrence of oral ulcers may increase. Genetic susceptibility may lead to oral mucosa being more sensitive to certain stimulation factors, prone to damage and inflammatory reactions. 2. Immune factors The abnormality of the immune system plays an important role in the formation of oral ulcers. When the immune function of the body is reduced or disordered, the resistance of the oral mucosa is weakened, and it is easily affected by the invasion of pathogens or autoimmune reactions, thus causing ulcers. 3. Mental psychological factors in a long-term state of mental stress, stress, anxiety, depression, etc., may affect the body's endocrine and immune system, leading to the occurrence of oral ulcers. Emotional fluctuations may cause the body to release some inflammatory mediators, causing damage to oral mucosa. 4. Nutrient deficiency Vitamin B12, folic acid, zinc and other nutrients may be related to the occurrence of oral ulcers. These nutrients are essential for the normal repair and metabolism of oral mucosa, and lack of them is easy to cause mucosal lesions. 5. Local irritants such as inappropriate dentures, sharp cusps, excessive brushing force, etc. may cause mechanical damage to the oral mucosa and induce oral ulcers. In addition, eating spicy and irritating foods may also irritate the oral mucosa. 6. Systemic disease factors Some systemic diseases such as digestive system diseases, blood system diseases, etc. may also be accompanied by oral ulcer manifestations. These diseases may indirectly lead to oral mucosal lesions by affecting the physiological state of the whole body. In summary, the occurrence of oral ulcers is the result of a combination of factors. In daily life, maintaining good living habits, balanced diet, stable emotional state, etc., is of great significance for preventing and reducing the occurrence of oral ulcers. If oral ulcers occur frequently or persist, seek medical attention in time to rule out the possibility of other potential diseases.
