Root Canal Treatment in Chatswood

The aim is to keep a natural tooth, when assessment shows that this is a sound option. At iCare Family Dental, root canal care begins with diagnosis: understanding what is happening inside and around the tooth, whether it can be restored, and which treatment choice makes sense for you.

Root canal treatment may be recommended when the soft tissue inside a tooth — called the pulp — is infected, irreversibly inflamed or otherwise too damaged to recover. The affected tissue is removed, the narrow spaces inside the roots are cleaned, disinfected, filled and sealed, and the tooth is then protected with a suitable restoration.

Can a tooth need root canal treatment if it does not hurt?

Yes. A tooth can have a problem even when it does not hurt. If the pain stops, that does not necessarily mean the tooth has recovered. If you know you have a deep cavity, a cracked or injured tooth, or a concern from an earlier check-up, let us check it. We may use tooth tests or an X-ray to find out what is happening.

If pain or swelling feels urgent

Arrange prompt dental assessment for severe pain, facial or jaw swelling, fever, a bad taste or a suspected dental abscess. If swelling affects breathing, swallowing or speaking, or extends to the eye or neck, seek emergency medical care.

How we check whether you need root canal treatment

We start by asking what you have noticed, when it started and what makes it better or worse. We check the tooth and nearby gums, and use appropriate tests to understand how the tooth responds. We also check whether enough healthy tooth structure and support remain to restore the tooth after treatment.

An X-ray may be used when a problem inside the tooth or around its roots is suspected. It can help show the roots, the surrounding bone, changes that may be associated with disease, and features that may affect treatment planning. When clinically indicated, X-rays may also be used during treatment to guide or check the work, at completion to assess the root filling, and later to monitor healing.

What root canal treatment actually does

Root canal treatment does not remove the tooth or its roots. It removes damaged or infected pulp from the spaces inside them. The clinical name is endodontic treatment.

The treatment can be understood in three stages.

  1. Diagnose and plan

    We check whether your tooth can be restored, explain the proposed treatment and talk through the alternatives with you. We then numb the tooth and the area around it with local anaesthetic for treatment.

  2. Clean, disinfect, fill and seal

    A rubber dam usually keeps the treatment area clean and dry. We make a small opening in the tooth to reach the pulp space, remove the damaged tissue, then carefully clean, shape and disinfect the canals before filling and sealing them.

    If the work is staged over more than one appointment

    If your treatment takes more than one appointment, we may place a temporary filling between visits. The number and spacing of appointments depend on the diagnosis, the tooth and how complex the treatment is. Once we have checked your tooth, we can give you a clearer idea of the stages and timing.

    Antibiotics alone do not clean and seal an infected root canal. They may be considered for particular signs of spreading infection, but they do not replace treatment of the source.

  3. Restore and protect the tooth

    Once the canals are sealed, the opening and damaged part of the tooth still need to be rebuilt. Depending on the tooth, this may involve a filling or a crown. A well-sealed final restoration helps protect the tooth and reduce the chance of bacteria entering again.

Will root canal treatment hurt?

Root canal treatment is normally carried out with local anaesthetic. With local anaesthetic alone, you remain awake while the tooth and nearby tissues become numb. You may notice pressure, movement or vibration during treatment. If you feel pain or become concerned, tell us so we can pause and reassess your comfort.

When the anaesthetic wears off

When the anaesthetic wears off, the tooth and surrounding area can feel tender for a short time, particularly if there was pain or infection beforehand. The experience varies from person to person.

If dental treatment makes you anxious, let us know at your consultation. We can talk through what to expect, how to let us know you need a break, and the comfort options available to you.

Why might I need a filling or crown afterwards?

The material inside the roots seals the canal system; it does not rebuild the chewing surface or replace tooth structure lost to decay, cracks, old fillings or the access opening. The tooth therefore needs a final restoration.

A filling may be suitable in some situations. A crown may be recommended when the tooth has lost more structure or needs greater protection from biting forces.

The decision can depend on:
  • whether it is a front or back tooth
  • how much natural tooth remains
  • whether cracks or large restorations are present
  • the forces placed on the tooth when you bite and chew.

Not every root-treated tooth needs a crown. We will explain which restoration we recommend for your tooth, why, and when it would be fitted.

Recovery and looking after the tooth

Your mouth may remain numb for a few hours after local anaesthetic. Follow the instructions given for your appointment, and avoid chewing until the numbness has worn off so you do not accidentally bite your cheek or tongue.

Some tenderness around the tooth, particularly when biting, can occur as the surrounding tissues settle. Ask us or your pharmacist which pain relief is suitable for you.

While a temporary filling is present

While a temporary filling is present, or before the tooth has its final restoration:

  • avoid hard or heavy chewing on that tooth
  • brush and clean between your teeth as advised, taking care around the treated area
  • keep every appointment needed to complete and restore the tooth
  • follow any instructions specific to your tooth and medical history.

Contact us if pain is severe, gets worse or does not settle; if swelling develops; if your earlier symptoms return; or if a temporary filling or restoration comes loose. Seek emergency medical care if any of the medical emergency signs above develop.

Risks, healing and retreatment

Root canal treatment is intended to control disease and retain the tooth, but no dental treatment has a guaranteed result. A tooth may not heal as expected, or infection may persist or return later.

Possible issues include

Possible issues include difficult or previously untreated canal anatomy, recurrent infection, damage to the root, a fine treatment instrument becoming stuck or breaking inside a canal, discolouration, or the tooth or restoration cracking. New decay, a leaking or broken filling or crown, or a later fracture can also allow bacteria back into a previously treated tooth.

If symptoms or signs of disease remain or return, the tooth needs another assessment. Depending on the cause and whether the tooth can still be restored, the options may include repeating the root canal treatment, surgery around the root tip, another restoration or extraction. Further treatment can sometimes retain the tooth, but it is not suitable or predictable in every situation.

When might an endodontist be involved?

A specialist opinion or referral may be considered

Root canal treatment can be provided by a general dentist or an endodontist, a dentist who specialises in this field. A specialist opinion or referral may be considered when the diagnosis is uncertain, the root and canal anatomy is complex, there is a significant crack or injury, a tooth has already had root canal treatment, or a complication needs specialist management.

After checking your tooth, we will explain whether treatment at iCare or a specialist referral is the more appropriate next step.

Root canal treatment or extraction?

Root canal treatment aims to retain the tooth. Extraction removes it. Which choice is more appropriate depends on more than the presence of infection.

The discussion may include:
  • whether the tooth can be predictably restored
  • the extent and position of any crack or damage
  • the support around the tooth
  • the complexity and likely limitations of treatment
  • the filling or crown the tooth would need afterwards
  • your priorities, overall dental plan and the fees involved.

If a tooth cannot be restored or has a poor outlook, removal may be the more appropriate choice. If it is removed, whether and how to replace the missing tooth is a separate decision.

What affects the cost of root canal treatment?

The fee depends on the tooth and the proposed treatment.

The fee depends on the tooth and the proposed treatment. Factors can include which tooth is involved, the number and shape of its canals, the diagnosis and complexity, whether it is first-time treatment or retreatment, the appointments and imaging needed, and the final filling or crown. A specialist consultation or treatment may have separate fees if referral is recommended.

After checking your tooth, we will explain the recommended stages and costs so you can decide whether to proceed.
