Root Canal treatment

Indications for treatment

  • Where an area of infection is apparent from an x-ray
  • Where Decay has been found close or into the pulp of the tooth (nerve)
  • Where symptoms correspond to other evidence gathered

 

Root Canal filling procedure

Root canal treatment is usually completed in two separate stages. On your first Root Canal appointment, the dentist will drill into the tooth and removed the infected pulp from the tooth. The canals are then located with files, cleaned out with an antibiotic paste and shaped for the next stage. Your dentist will place a temporary filling to protect the tooth until the next stage can be completed.

The second and final stage to a Root Canal Filling is where your dentist fills the prepared canals with a special rubber material. Our aim on this appointment is to fill the tooth right to the end of the root where the infection may still be lying. This seals the bacteria free canals and then either an amalgam, resin or crown restoration is placed over the top to protect the tooth.

 

What will my tooth look like after Root Canal?

We usually recommend crowning Root Canal filled teeth as after this treatment they are prone to fracture as they become more brittle. There are many different crowns you can choose to have and your dentist will guide you in making an informed decision about which one to have. We often drill the tooth for a crown at the second stage of Root canal treatment so a crown can be produced by the lab and fitted at a faster turnover. Occasionally we do like to wait a while before crowning to see if the root canal treatment has been successful and no symptoms have re-occurred.

 

How successful is Root canal?

Root canal treatment usually has a high success rate of up to 90%. The success rate depends entirely upon the standard of the root canal filling, and if there has been any factors during the procedure lowering the success. If a tooth has already been root canal filled and we are re-doing the root canal a second time, this can lower the success rate also.

Root canal treatment may take several lengthy appointments, and this is depending on how many roots and therefore canals a tooth has to fill.

 

Patient example of a Root Canal Treatment:

A patient came to us with symptoms of a dull throbbing ache which was very tender to bite on. We took an x-ray and saw a dark circular area around the root of the second premolar which told us she had an apical abscess. Root canal treatment was proposed to try and save the tooth from extraction and was successful. The root Canal filling goes all the way to the end of the canal in the tooth, even despite getting around the very curved root you can see on this x-ray.
