When infection or tooth decay reaches the inside of the tooth (the pulp chamber) it can destroy the nerves in the root of the tooth. A root canal treatment is the process used to treat the infection and save the tooth.

Why do I need a root canal treatment?

If your tooth is badly damaged or infected, your dentist may recommend a root canal treatment to repair damage to the inside part of the tooth. When bacteria gets inside the pulp chamber, it can multiply quickly. Antibiotics by themselves can’t get into the tooth to kill the infection and an abscess can form in the root and eventually cause the tooth to die.

The goal of root canal treatment is to save your tooth. Missing teeth can cause other problems in the mouth, face and jaw. There are other treatments to replace missing teeth but these are more complex and where possible we will always try to save the tooth first.  

Is root canal treatment painful?

The pain people often associate with root canal treatment is usually caused by the infected pulp of the tooth. This causes extreme toothache, sensitivity to hot or cold, swelling or tenderness in the gums. In some cases your tooth may also feel loose. Removing the infection will help with pain. 

The treatment itself is similar to having a filling, although it can take longer. Our dentists have a range of anaesthetic options available to help you feel comfortable and pain free during your treatment.

How many appointments will I need?

Our dentists use latest 3D scanning technology to assess the extent of the infection and plan your root canal treatment. We need to allow time in between appointments to make sure the infection is completely cleared before the tooth can be restored. Trying to shortcut the treatment can cause ongoing issues. If there is any bacteria remaining in the nerve canals, the infection can return.

What to expect during your treatment

• We take an x-ray of your tooth and surrounding bone to see the extent of infection.

• Local anaesthetic will be applied to numb the area before the infected pulp inside the tooth is removed and replaced with a sterile dressing.

• A temporary filling will be applied between treatments to allow time for the infection to settle.

• Each tooth has between 1 and 4 canals. When all canals are cleaned, shaped and clear of infection, the space will be filled and supported with sterile material.

• At the end of the process, a crown is often needed to protect the tooth and prevent it from cracking.

How much does it cost?

The cost of root canal treatment can vary depending on the extent and location of the infection. For example, a front tooth with one canal will require less intensive treatment than a back tooth that has up to four canals.

Our dentists will provide a detailed explanation of your diagnosis and treatment plan. Our goal is always to help save your tooth and restore a healthy, pain-free smile as quickly as possible.
