How Dentists Create a Root Canal

Video Transcript

When we need to do root canal, we need to go into the chamber of the tooth. The chamber basically previously consists of the blood supply and also of the nerve tissue. They're all situated on the inner part of the tooth and so what we have to do for the most part, when you get a cavity, the cavity is on the top surface or from the side, it breaks through the enamel and into part of the tooth structure and then basically exposing these inner part nerve tissue and the blood supply. So what we have to do is eliminate those cavities so when we do the drilling, for the most part we go on the top exposing this area and cleaning out the chamber from the top portion of the tooth. Once that's all done, this area is sealed with a rubber-based material, and in doing so, the bacteria from outside cannot go in and from the top, cannot go back out. So then that tooth is protected and once its protected, that tooth should be able to function back like a normal tooth.
