James is afraid of dentists. An x-ray technician took x-ray of his teeth. He has three cavities. The dentist is drilling two of the cavities, but he will have to pull out the tooth that has the third cavity. That cavity is so large that it can't be filled. That is also the tooth that is causing the pain. Every time the dentist starts the drill, James clinches with fear. The dentist told him to relax, but he can't. What can he do? How can relax?
