What are the alternatives to a root canal?

My dentist is 95% sure I will need a root canal tomorrow. He won't know for sure until he drills and looks into the tooth. What are the whollistic alternatives to a root canal? The dentists say the only alternative is to extract the tooth. (I'm the same Celia who has posted on your website my successfull liver/gallbladder cleanses while pregnant and nursing.) Thank you! If possible, please answer quickly.
