Endodontics (Root Canal Treatment)

Endodontistry, what is commonly called root canal treatment, is an involved dental treatment. It may sound daunting but where it is required failure to undergo the treatment will result in the loss of the affected tooth. At Chiswell Green our goal is to save your natural teeth where possible and with the minimum discomfort to you.

The aim of endodontic treatment is to resolve apical periodontitis, which is an infection that can affect the tooth and its surrounding tissues. Root canal treatment kills the bacteria that penetrate into the tooth, remove the dead tissues from the inside of the tooth and fill the tooth, in order to prevent a new infection.

Dr Peru is a Registered Dental Specialist with advanced education in root canal therapy. He is specially trained to diagnose and manage conditions that, if not treated, will certainly cause infection, pain and tooth loss. All dentists receive basic training in root canal treatment in dental school. However, because endodontic retreatment can be more challenging than providing first-time treatment, many dentists refer patients needing endodontic retreatment to speicalist endodontists such as Dr Peru. Endodontists are dentists with additional years of advanced education in diagnosis and root canal treatment. Because they limit their practices to endodontics, they treat these types of problems every day.

In some cases a tooth that has been treated previously will become painful or diseased months or even years afterwards, or the infected tooth may not be giving any pain at all and the inflammation can go on for years undetected (chronic apical periodontitis) until it becomes painful or is detected from routine X-ray dental examination. If your tooth has not healed or has developed new problems, you have a second chance. Another procedure, endodontic retreatment, may be able to save your tooth. Dr Peru is a registered specialist in such procedures.

Endodontists are experts in performing nonsurgical and surgical retreatment. Endodontists may use advanced technology, such as operating microscopes, ultrasonics and digital imaging to perform these services.

Root Canal Treatment Procedure

It usually takes 1-2 visits (from one hour to one and half hours for each appointment) to carry out root canal treatment or re-      treatment. Additional visits might be necessary due to particular circumstances (e.g.: anatomical or technical difficulties).

The process is as follows:

  • Preoperative radiograph – a small radiograph (X-ray) of the tooth is taken before starting the root canal treatment.
  • Isolation of the infected tooth from the rest of the mouth – the infected tooth is isolated from the rest of the mouth applying a special rubber sheet called rubber dam
  • Mechanical cleansing of the root canals – the inside of the tooth is then mechanically cleaned using precision instruments and rinsed thoroughly using several solutions able to kill the bacteria that cause the infection
  • Root canals obturation – at a subsequent visit the root canals are filled using guttapercha coated with a special root canal sealer. Guttapercha is a rubber material chosen for its strength and durability.
  • Placement of a temporary filling onto the tooth – again the resistant temporary filling material is placed onto the tooth to prevent infection of the tooth before a permanent restoration is placed
  • Permanent restoration of the tooth – after the endodontic retreatment is completed, you will need to return to your dentist as soon as possible to have a new crown or other restoration placed on the tooth to protect and restore it to its full function
