What is root canal treatment?   Root canal treatment (aka endodontic treatment) is a dental procedure usually performed when (1) the "nerve" (pulp) is dying or dead, and (2) there is an associated infection inside the tooth, and (3) inflammation of the tissues around the tooth.

What does root canal treatment involve?   Essentially root canal treatment involves cleaning the infection from "tunnels" (root canal system) inside of the tooth and sealing the space left with a root filling to prevent reinfection.  Fine dental instruments and disinfectants are used during cleaning.  The root filling material is usually a rubbery filling called gutta percha.  Several small dental "x-rays" (radiographs) are taken during the procedure.

What is the purpose of root canal treatment?   To allow the tissues around the tooth to heal and stay healthy so that the tooth can be retained and restored to function.

How many visits are required?   On average 1-3 visits, each approximately 1-2 hours in duration.

Why does root canal treatment take so long?   The "tunnels" (root canal system) may be complex, narrow, curved, or blocked.  It is important to take time to ensure the inside of the tooth is thoroughly cleaned and sealed.

How can I relax during treatment?   You are welcome to bring your own headphones and music to listen to.  A rubbery prop can be placed between your upper and lower teeth to help your mouth stay open.  Some patients even catch up on some sleep and take a nap.

What is the success rate?   Research reports the success rate of root canal treatment to be in the region of 90%.  The success rate of root canal re-treatment is in the region of 80%.  Traditionally, success means your tooth should be symptom-free and without signs of infection or inflammation.

What are the alternatives to root canal treatment?   (1) No treatment, which is not advisable as there is a risk of spreading infection  OR  (2) Removal (extraction).  The resulting space may be restored with an implant, bridge or denture.

Will there be pain during treatment?   There are unwarranted horror stories about root canal treatment.  Most patients do not experience any pain during treatment with local anaesthetic.

Will there be pain after treatment?   It is likely the tooth and gum will be "bruised" or tender for a number of days after treatment.  It may be necessary to take painkillers and avoid chewing directly on the treated tooth for a few days.  It is unlikely, but a small number of patients develop a dental abscess after treatment.  If you experience facial swelling and pain, please contact your dentist or an emergency clinic as you may require antibiotics.

What further dental care is recommended?   It is recommended that you attend your dentist as soon as possible for a dental restoration, e.g. crown or onlay, to protect your tooth from cracking or splitting.  It is paramount that you keep your teeth and gums clean, eat a healthy diet with a low frequency intake of sugar, and attend your dentist for regular check-ups.
