A root canal is a treatment of the pulp of the tooth that is inflamed, infected, or dead. The pulp is a soft substance in the center of the tooth that consists of nerve, blood vessels, and connective tissue. The pulp chamber is the hollow part in the center of the tooth that contains the pulp, and it continues down canals that extend through the roots of teeth and into the surrounding bone. Some roots have more than one root canal, but all have at least one canal.
Root canal Procedure
To confirm that a tooth does indeed require root canal treatment, the dentist will take an X-ray of the root the root canal will be completed in either one or two appointments. The dentist will determine whether the root canal will be treated in one or two appointments based on the size and duration of an abscess and other factors. A tooth is likely to be treated in two appointments if it is getting a re-treatment (being treated a second time).
In actual root canal treatment , the dentist will numb the tooth with local anesthesia ensure patient comfort. When the tooth has become sufficiently numb, the dentist will place a rubber dam over the tooth. pulp is removed from the chamber and canals. The canals are then cleaned with r disinfecting solution. The canals are then shaped with a series of files of increasing diameter to make sure all of the infected tooth structure is removed and there is room for an adequate root canal filling. A series of X-rays will be taken throughout the procedure to make sure the files are reaching the end of the root and all the canals are being adequately cleaned and shaped. The canals are filled with a rubber-like material called gutta percha surrounded by a sealing paste. After the root canal is completed, the tooth will likely need a crown to protect it from fracturing in the future. A post may be placed down one of the canals to provide an anchor for the filling and the tooth will be built up with a permanent filling. The dentist may choose to do the crown immediately, or may wait a brief period of time to make sure the tooth is free of pain before continuing with the crown.
