Mouth sores can range from harmless and uncomfortable to painful and serious. Some of the more common types of toddler mouth sores include canker sores, cold sores, and thrush. Canker sores are small, white ulcers that usually appear on the inside of the cheeks or lips and can cause pain, redness, and swelling. Cold sores are caused by the herpes simplex virus and usually appear on or around the lips. Thrush is an infection caused by the fungus Candida albicans and appears as white patches in the mouth that can be wiped away.

There are many potential causes of toddler mouth sores, including bacterial or viral infections, allergies, or vitamin deficiencies. In some cases, the cause of the sores may be unknown. It is important to note that mouth sores can also be a sign of a more serious underlying condition, such as celiac disease or Crohn’s disease, so it is important to consult with a doctor or dentist if the cause is unknown.
