Root Canal Treatment

Relieve pain. Save your natural tooth.

Root canal treatment is designed to treat infection or inflammation inside a tooth while preserving the natural tooth whenever it can be successfully restored.

01Pain Relief

Treats the source of pain when infection or inflammation affects the tooth's pulp.

02Natural Tooth

Helps preserve your natural tooth whenever it can be predictably restored.

03Infection Control

Removes affected tissue and cleans the root canal system.

04Restoration

The treated tooth can be restored to regain useful function.

What is Root Canal Treatment?

Treat the infection. Keep the tooth.

Inside every tooth is a soft tissue called the pulp. It contains nerves and blood vessels.

When this tissue becomes infected or inflamed because of deep decay, trauma or other damage, root canal treatment removes the affected tissue, cleans the canal system and seals it.

The tooth is then restored with an appropriate filling or crown depending on the amount of remaining tooth structure.

The objective

Save the natural tooth whenever possible.

RCT is not about simply "removing the nerve". It is a complete treatment designed to eliminate infection from inside the tooth and allow the tooth to be restored.

When might you need it?

Don't ignore persistent symptoms.

Not every toothache requires a root canal. A clinical examination and appropriate diagnostic tests are needed to determine the cause.

Persistent tooth pain Pain that continues, returns repeatedly or becomes increasingly severe.
Lingering hot/cold sensitivity Sensitivity that continues after the hot or cold stimulus has been removed.
Pain while biting Pain or discomfort when chewing or putting pressure on the tooth.
Swelling or tenderness Swelling or tenderness around the affected tooth or gums.
Deep decay Decay that may have progressed close to or into the pulp.
Repeated infection Recurring infection or a problem involving a previously treated tooth.

Step 01 — Diagnosis

Before treatment, we find the cause.

A root canal should not be recommended simply because a tooth hurts. The dentist first determines what is causing the symptoms and whether the tooth can be successfully treated and restored.

01
Clinical examination The tooth, surrounding gums and symptoms are assessed.
02
Diagnostic imaging X-rays or other appropriate imaging may be used to evaluate the tooth and surrounding structures.
03
Treatment planning The dentist determines whether RCT, another treatment or extraction is appropriate.

The treatment

What happens during an RCT?

Root canal treatment involves cleaning and disinfecting the inside of the tooth before sealing and restoring it.

Root canal treatment process

01

Anaesthesia

Local anaesthesia is used to numb the area and keep the procedure comfortable.

02

Access

A controlled opening is made to reach the infected or inflamed pulp inside the tooth.

03

Clean & Shape

The canals are cleaned, disinfected and shaped to prepare them for filling.

04

Seal & Restore

The canals are sealed and the tooth is restored with an appropriate restoration.

Inside the tooth

Cleaning the canals is the heart of the treatment.

Once access to the pulp chamber and root canals has been established, the affected tissue is removed. The canal system is cleaned and shaped before it is filled and sealed.

Remove infected tissue The affected pulp is removed from inside the tooth.
Clean and disinfect The root canal system is cleaned to reduce bacteria and infected material.
Shape the canals The canals are prepared so they can be properly filled and sealed.
Fill and seal The cleaned canals are filled and sealed to help prevent reinfection.

Why preserve the tooth?

When possible, save what you have.

A successfully treated and restored natural tooth can continue to provide useful function.

01

Natural Tooth

Preserves the natural tooth instead of removing it when the tooth can be successfully treated.

02

Infection Control

Removes infected or inflamed tissue from inside the tooth.

03

Function

Once appropriately restored, the tooth can return to useful chewing function.

04

Oral Health

Keeping a restorable natural tooth can help maintain the existing dental anatomy and function.

Important to know

Benefits, limitations and alternatives.

Possible risks & limitations

  • Mild pain or tenderness may occur after treatment and is usually temporary.
  • Some cases may require more than one appointment, depending on the tooth and infection.
  • A treated tooth may require a crown or another protective restoration.
  • Root canal treatment does not guarantee that every tooth will heal successfully.
  • In some cases, further treatment or extraction may ultimately be required.

Alternative option

If a tooth cannot be predictably restored, or if a patient chooses not to undergo root canal treatment, extraction may be considered.

If extraction is required, replacement options such as an implant, bridge or removable prosthesis may subsequently be discussed depending on the individual case.

Your dentist will explain the available options and their advantages and limitations before treatment.

After the root canal

Treatment isn't finished until the tooth is restored.

After the canals have been treated, the tooth needs appropriate restoration to protect the remaining tooth structure and return it to function.

Follow the dentist's instructions Take prescribed medicines exactly as advised, if medication is required.
Avoid unnecessary pressure initially Follow the advice given regarding chewing on the treated tooth.
Complete the final restoration A filling or crown may be required depending on the remaining tooth structure.
Attend follow-up appointments Follow-up helps assess the tooth and complete the planned restoration.

Frequently Asked Questions

Questions patients often ask.

Is root canal treatment painful? +

The area is numbed during treatment. Modern root canal treatment is designed to treat the source of dental pain while keeping the procedure as comfortable as possible.

How long does an RCT take? +

Treatment time depends on the tooth, the complexity of the canals, the infection and the required restoration. Your dentist can explain the expected treatment schedule after examination.

Will I need a crown after RCT? +

Some teeth require a crown or another protective restoration after root canal treatment, especially when a significant amount of tooth structure has been lost.

Can an RCT save my natural tooth? +

Root canal treatment is intended to treat infection inside the tooth while preserving the natural tooth whenever the tooth can be predictably restored.

What happens if I delay treatment? +

Dental infection may worsen over time. Persistent pain, swelling or sensitivity should be evaluated so the cause and appropriate treatment can be determined.

Is extraction the only alternative? +

If the tooth cannot be predictably restored or root canal treatment is not chosen, extraction may be considered. Replacement options can then be discussed based on the individual case.
