Girls, hi. Both of our daughters have stomatitis. They're feverish, they won't eat anything, the younger one even sucks on a teething ring. There are ulcers on their tongue and cheeks. We called the doctor, but she hasn't come yet. Can you tell us how this stomatitis is treated? We've never had it before.
