Please consult a child specialist physically for clinical examination.

Frequent mouth ulcers in children are called recurrent aphthous stomatitis, and in a 9-year-old the most common underlying cause is a nutritional deficiency — particularly Vitamin B12, iron, folic acid, or zinc. These deficiencies are very common in Indian children and can easily trigger repeated painful ulcers in the mouth. Other contributing factors include: minor trauma from hard or sharp foods, toothpastes containing sodium lauryl sulfate (SLS) which irritate the mouth lining, stress or immunity-related issues, and occasionally gluten sensitivity. If the ulcers are very frequent (more than 3-4 times per month), an underlying immune or gastrointestinal issue should be ruled out.
