How is Root Canal Treatment Performed

Root Canal Treatment in Toronto – Have you ever experienced a sharp, stinging pain in your teeth immediately after taking a hot or cold drink that does not go away even after you have stopped the intake of the fluid? If that’s the case, then you are having an infection of the dental pulp in your teeth, known as pulpitis. While in the initial stages, pulpitis is reversible, and easily treatable by removing caries from the affected tooth, and restoring it with a suitable filling, if the condition is ignored, the infection tends to travel to the regions surrounding the tooth, and becomes irreversible. At this stage, the only option left with the dentist to restore the tooth, is to perform a root canal treatment.

What is Root Canal Treatment?

The root canal treatment involves the removal of infected pulp from the crown and root portion of the tooth, followed by a thorough cleansing of the root canal. Finally the root canal is filled with an inert and biocompatible material, so as to prevent re-infection.

How Is Root Canal Treatment Performed?

  • Radiographic Evaluation of the Tooth pulpitisRadiographic Evaluation of the Tooth – Before starting with the procedure, the dentist orders various x-rays of the affected tooth of the patient, in order to assess the current condition of infection, the anatomy and shape of the root canal, as well as the presence of any important nervous or vascular landmarks that might get damaged during the procedure.
  • Local Anesthesia – since the dentist has to remove the dental pulp, which is a highly sensitive tissue, the procedure is performed under the effect of a local anesthesia. Depending upon the tooth involved, usually it takes about 5 minutes for the anesthetic agent to take effect. In case the pulp is already dead due to a long standing infection, local anesthesia may not be required.
  • Preparation of the Access Cavity – next, the dentist gains an access into the tooth’s pulp chamber, which is performed by drilling a hole in the tooth, until a direct access to the pulp is achieved. The dentist then slightly expands the access hole to allow easy insertion and removal of instruments while removing the pulp.
  • Pulp Removal root canal treatment-north-yorkPulp Removal – Removal of the pulp is mainly performed with the help of endodontic instruments known as the dental files. The infected pulp and the bacterial debris attaches to the files, which is then carried out of the tooth. During the procedure, continuous irrigation with saline, sodium hypochlorite or any antibacterial agent is performed along with the use of powerful suction , so as to ensure that no bacterial debris or infected pulp is left behind

  • Root Canal Preparation – The dentist then prepares the shape of the root canal cavity by using successively using files with a larger diameter, such that it is flared at the top, while constricted at the lower end.
  • Sealing the Root Canal – This procedure is known as Obturation, and is performed by placing an inert material into the root canal. In some cases, dentists like to delay Obturation of the root canal, until complete healing has ensued, which is evident by absence of pain or any fluid discharge from the tooth. The material most commonly used for this purpose is a rubbery material known as “gutta percha”, which can either be used in the solid or molten form.
  • Tooth Restoration – Immediately after root canal treatment, the dentist places a temporary filling over the tooth, which is replaced with a permanent filling once the tooth has healed completely.
  • Provision of a Tooth Crown – since the tooth becomes brittle after root canal treatment, it should be strengthened by placing a dental crown over it. The crown not only supports the remaining tooth structure, but also restores the anatomy and chewing efficiency of the tooth.

What to Expect After Root Canal Treatment?

While healing of the tooth is in progress after root canal treatment, it is best to avoid using that side of the mouth for chewing, and minimizing putting loads on the tooth. In addition, it is normal for some patients to feel slight discomfort as a result of inflammation, which can be relieved by taking any anti-inflammatory medication provided by your dentist. Finally, the success of the root canal treatment is dependent upon the maintain ace of oral hygiene by the patient. Regular tooth brushing and flossing, in addition to seeing your dentist periodically will can ensure that the procedure becomes a success.
