I have a 3 year old with a sore in his mouth. It is between his upper lip and his gums at the very top. It looks like a white circle and it has a red streak coming down to his teeth.
Hand, foot and mouth disease is the most common cause of mouth sores in children, primarily in the age group from six months to three years old. It is caused by a group of viruses called enteroviruses, most commonly, the coxsackievirus A16.
