This is what I am hoping. She’s had her hands constantly in her mouth past few days xx
My son gets this when his mouth is dry and it cracks.Definitely not a cold sore x
Picture is not too clear, but if it started as a cut by the corner of the mouth, it could mean a lack of vitamins. Usually comes when one is not well and dehydration. Can easily be resolved.
Could she have scratched her mouth rubbing her face if her teeth are hurting?
