Picky eating in children often leads to recurrent mouth ulcers.

Oral ulcers are a common mucosal disease characterized by one or more painful, round or oval sores inside the mouth, typically with a white center and red border. They can be caused by various factors, including genetic predisposition, immune system disorders, nutritional deficiencies, psychological stress, oral trauma, or certain food allergies. Children who are picky eaters may not receive balanced nutrition, especially key nutrients essential for oral mucosal health such as B vitamins, vitamin C, iron, and folic acid. Deficiencies in these nutrients can weaken the oral mucosa, making it more susceptible to ulcer formation. Therefore, for picky eaters who frequently develop oral ulcers, parents should encourage a varied diet and, when necessary, consult a nutritionist to ensure the child receives adequate nutrition. Additionally, maintaining good oral hygiene, avoiding hard, hot, or irritating foods, and seeking medical advice when needed are important steps to identify the underlying cause and receive appropriate treatment.
