My 3-year-old child has several ulcers in their cheeks, lips, and on their tongue, should we do something about it?

If your 3-year-old child has multiple ulcers on their cheeks, lips, and tongue, it may be caused by factors such as fatigue, illness, consuming irritating or hot foods, or a small abrasion. These lesions often heal on their own within 7 to 10 days. You can help reduce the pain with Tylenol and avoid eating irritating foods. If the number of lesions continues to increase or if they persist for more than 7 days without improvement, it is advisable to consult a healthcare professional.
