Root Canal
Root canal treatment is a procedure wherein the dental surgeon removes the tooth's pulp which is a tissue similar to a small thread in the center of the tooth. The surgeon then cleans the remaining space gives it a shape and fills it after he removes the damaged, diseased or the dead pulp. This procedure seals off the root canal. Earlier, the dentists used to remove the entire teeth with injured or diseased pulp. However, today, with advanced technology, this procedure saves several teeth that would otherwise be lost. There are many reasons that lead to the teeth getting damaged or injured and the most common out of them are:
- Tooth which gets broken
- A deep cavity
- Tooth getting injured, for instance a serious knock to the tooth, either recently or in the past
Once the pulp gets infected or dead, it must be treated instantly; if left untreated pus can accumulate at the tip of the root in the jawbone thus leading to the formation of an abscess. This abscess can further destroy the bone surrounding the tooth and cause pain.
Root Canal Procedure
The steps involved in this procedure:
- Initially, the surgeon makes an opening through the back of the front tooth or the crown of a molar or pre-molar.
Then the surgeon removes the diseased pulp after which he cleans, enlarges and shapes the root canals and the pulp chamber as a preparation for filling it. - If the patient needs to visit for more than one time then a temporary filling is placed in the crown opening to protect the tooth between dental visits.
- The surgeon then removes the temporary filling and the permanently fills the pulp chamber and the root canal. A tapered and rubbery material known as gutta percha is then inserted into each of the canals and is often sealed into the appropriate place with cement. At times, the dental surgeon also places a metal or plastic rod in the canal for structural support.
- Finally, the surgeon usually places a crown over the tooth to reinstate its appearance and natural shape. If the tooth is extremely broken down then a post might be required to build it up before a crown is placed.
