DD has a long white sore along the top of her gum. Very painful. I don't think its an ulcer because its not round or oval and it just doesn't really look like one as its a really bright white. It actually looks a bit like the bit between the gum and lip is torn but with white stuff there instead of blood. What could it be? And what can I do to ease the pain? They don't sell bonjela in my country.
Here's a rather rubbish photo I tried to take of it, can barely see it in here.
