Painful, red gums and mouth sores

[Guest guest]

My daughter bottom gums are red and painful and it really hurts her

when I brush her teeth. And recently, I noticed that she also has

sores in her inside bottom lip and on her tongue.

I've read in the archives that herpes can cause sores, but are these

on the lips or inside the mouth? I used to get herpes cold sores but

they were always on the lips not in the mouth.

Any ideas about what is causing the sores and the red gums? And what I

can give her that may help for both problems?

Thanks,
