What causes mouth ulcers in children in Chongqing?

The causes of oral ulcers in children in Chongqing may involve several factors. 1. There is a certain relationship with family genetics; if one or both parents have a history of oral ulcers, the child's risk of developing the condition may increase by 60%. 2. Poor nutrition and deficiencies in vitamins and trace elements—such as iron, zinc, folic acid, and vitamin B2—are common triggers for oral ulcers. 3. Low immune function, especially in young children whose immune systems are not yet fully developed, makes them more susceptible to viral infections that can lead to ulcers. 4. In addition to the above, emotional fluctuations and psychological factors such as stress, depression, and anxiety may also contribute to the development of oral ulcers. Furthermore, poor oral hygiene, including inadequate cleaning and frequent snacking, may increase the risk of oral ulcers. Parents should pay attention to their child's nutritional intake, emotional well-being, and oral hygiene, and seek timely medical treatment when necessary.
