How to remove cemented cap from your gums?

My 9 year old has a baby tooth that has a cap on it, and the tooth itself has come completely out. The problem is the silver cap over it is cemented to her front gums, not allowing the tooth to come out of her mouth. It is causing a lot of pain. Is there something i can get that will remove the cement to safely remove the tooth? Or is there a safe way to remove the tooth without having to take her in to the dentist?
