A Root Canal treatment involves removing the pulp inside the tooth, which is comprised of nerves, blood vessels and connective tissue. You will be completely frozen during this procedure and should not feel anything. The pulp is completely removed, and then the inside of the root is shaped and cleaned. Finally, the canal is filled with a rubbery material called gutta percha, which seals the root, preventing bacteria from growing inside the tooth.
The visible part of you tooth, or crown of the tooth, will have to be restored after the Root Canal treatment is completed. The inside of the crown will require a core to replace the missing tooth material, and if a lot of tooth is missing, a post may be required to bind the core to the remaining tooth. Finally, a crown will be required, to cover over all of the visible tooth and keep it together for the long-term.
After a Root Canal treatment, your tooth is no longer alive on the inside, but it is still held in place by living tissue, the periodontal ligament, which connects your tooth to the bone. A Root Canal treatment saves your tooth, allowing you to chew with it for many years to come.
