I am supposed to have a 3 root canals. I would rather not plus I can't afford them even with insurance. Two of the teeth I had root canals done to them over 5 years ago and I have to do it again ? Some have told me that they leak. So what is oil pulling ? How do I do that ? I am on the orad for two weeks and my teeth have been bothering me. I have been taking oregano oil and it helps a little with the pain. Is there an alternative to Antibiotics ? If so what ? Thanks
