If at all possible, avoid a root canal if you haven't had one already. Please look into reading the book The Root Canal Cover Up and find a holistic dentist that can assist you. If you must do a root canal— start the program 7-10 days AFTER your root canal. Make CERTAIN that you oil pull for 30 days in a row during this process. All the information about oil pulling is inside the course and here's a video on it. I would like any of you who have ever had a root canal to oil pull for 30 days, so that the bacteria in your mouth (oral microbiome) cannot defeat our efforts.
