Nonspecific sore: It is very likely that she has nonspecific mouth ulcer associated with viral illness. Canker sore is not common at this young age.

Canker sores/ herpes: It is most likely canker sores or herpes. If it is herpes (a dds would need to diagnose it), then a supplement called lysine is very effective and safe, but some what slow. Do not use lysine if child has phenylketonuria. There are also some anti-viral medications, but they are prescription. If canker sores, use a topical local anesthetic from the pharmacy.
