Children often suffer from recurrent aphthous ulcers, and the causes are multifactorial. 1. It may be due to an unbalanced diet, especially deficiencies in B-complex vitamins, vitamin C, and trace elements such as selenium, iron, and zinc. Deficiencies in these nutrients can easily lead to recurrent oral ulcers. 2. Poor oral hygiene habits, such as failure to rinse the mouth or brush teeth in a timely manner, may lead to bacterial or viral infections of the oral mucosa, thereby causing ulcers. 3. Children's immune systems are not yet fully developed, and their resistance is relatively weak, making them susceptible to pathogenic invasion, which can also contribute to frequent oral ulcers. 4. Psychological factors, genetic factors, and irritation of the oral mucosa caused by teeth during the tooth replacement period may also lead to the occurrence of oral ulcers. Therefore, parents should pay attention to children's diet and oral hygiene, and enhance children's immunity to reduce the occurrence of oral ulcers.
