Good Morning. My little who is almost 4 is complaining of having a sore mouth, when he's pointing to it, it's the roof of his mouth that he's point too. When I look inside his mouth, the roof of it is rather lined, with ridges on on the gums. Unsure whether this is normally how it is supposed to be, not having paid much attention to it before.
Wondered if this would be an infection?
Thank you.
