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.
Cold sores, despite the name, are not caused by the common cold. They are caused by a virus, specifically, the herpes simplex virus (HSV). Cold sores are contagious and are passed to others through direct contact or contact with body fluid.There are two different types of HSV-type 1 and type 2.anker sores affect the inside of the mouth and are not caused by the herpes virus. In contrast to canker sores, cold sores usually develop on the lip and not inside the mouth.
