Is my dentist financially reponsible for damage that he caused to my tooth?

Question Details: I had a crown on a good tooth 6 years ago. My current dentist said the crown has gaps and it needs to be replaced. So during the replacement of the crown, the dentist scratched too much of the tooth under the crown that he exposed the root inside the tooth. Now he says that a root canal needs to be done before the new crown is placed. He wants me to pay for it. Can I argue that I should not be paying for it?
