Before telling about root canal treatment endodontists in North Carolina tell their patient about the structure of the tooth. This information helps to understand how root canal treatment will be carried out and its main reason. Many people call the pulp tissue of the tooth, nerve. Certainly, the pulp contains nerves, but also arteries, veins, lymph vessels, and connective tissue. Every nerve enters the tooth at the very top of its root (or roots - if there are more than one). During root canal treatment endodontist cleans the inner part of the tooth forming an empty space. This space is filled with filling materials and that can not be destroyed by biological fluids. Consequently, during treatment are removed not only bacteria but also organic wastes which provide them food, in addition, bacteria do not have enough space for living.
