Kelly went to the dentist to get her teeth cleaned. He told her that she had a cavity that needed filling. Since Kelly felt no pain, she decided to postpone the filling. Robin went to another dentist to get her teeth cleaned. That dentist used an oral camera to take a picture of the tooth that needed to be filled. Once Robin saw the hole in her teeth, she was eager to have the tooth filled. How did the oral camera affect the credence qualities of the service?
