Deciphering Canker Sores in Toddlers
Canker sores are also called aphthous ulcers. They are tiny, open sores that show up on the soft parts of the mouth. This can be on the tongue, inside the cheeks or lips, on the roof of the mouth, or at the base of the gums. They are not the same as cold sores. Cold sores are caused by a virus and show up outside the mouth. Canker sores are not contagious. They do not spread from person to person.
For toddlers, canker sores can be very painful. They can make eating, drinking, and even talking hard. Most canker sores are small. They are usually less than 1 centimeter across. They often heal on their own in one to two weeks. But for a little one, even a small sore can cause a lot of fuss. It is important to know what signs to look for and how to help your child.
