Treatment to help save an infected or damaged tooth

Root Canal Treatment in Sandgate

Root canal treatment is used to treat the inside of a tooth when the dental pulp has become irreversibly inflamed, infected or damaged.

The aim is to remove the affected tissue, disinfect the internal root canal system and seal the tooth so it can remain in the mouth.

Root canal treatment can often save a tooth that might otherwise require extraction.

At Dental Seasons, we first assess whether the tooth can reasonably be restored and whether root canal treatment is the appropriate option.

What is the dental pulp?

Inside each natural tooth is a space containing soft tissue known as the dental pulp.

The pulp contains nerves, blood vessels and connective tissue.

It extends from the crown of the tooth down through small canals within the roots.

The pulp can become inflamed or infected because of:

  • Deep tooth decay
  • A crack in the tooth
  • A significant dental injury
  • Repeated dental treatment
  • Other damage that allows bacteria to enter the internal tooth structure

Once the pulp is irreversibly damaged, it cannot simply heal in the same way as a minor surface injury.

Signs you may need root canal treatment

Possible symptoms include:

  • Persistent or severe toothache
  • Pain when biting or chewing
  • Sensitivity to hot or cold that continues after the stimulus is removed
  • Swelling
  • A pimple or draining area on the gum
  • A tooth becoming darker
  • Deep tooth decay
  • Tenderness around a tooth

However, not every tooth needing root canal treatment is painful.

Some infections are identified during a dental examination or X-ray before severe symptoms develop.

Root canal treatment is designed to save the natural tooth

Dr Andrew Bachour, principal dentist at Dental Seasons Sandgate

If the pulp inside a tooth is irreversibly damaged or infected, the main options commonly become root canal treatment and restoration of the tooth, or removal of the tooth.

Keeping a suitable natural tooth avoids creating a missing-tooth space. However, saving a tooth is only sensible if the remaining tooth can be restored and has a reasonable prognosis.

A root canal should not be performed simply to keep a tooth that cannot subsequently be restored.

How do we determine whether a tooth needs root canal treatment?

Assessment may include:

  • Discussing the symptoms
  • Examining the tooth
  • Testing response to temperature or other stimuli
  • Checking tenderness to biting or pressure
  • Assessing the surrounding gums
  • Dental X-rays
  • Reviewing existing fillings, crowns or cracks

In selected complex cases, additional imaging or specialist endodontic assessment may be helpful.

The aim is to determine whether the dental pulp is likely to recover or whether irreversible damage or infection is present.

What happens during root canal treatment?

Local anaesthetic

The tooth is numbed to keep treatment comfortable.

Rubber dam isolation

A rubber dam is placed around the tooth.

This helps keep saliva and bacteria away from the treatment area and helps protect the mouth while small instruments and disinfecting solutions are used.

Access the pulp chamber

An opening is made into the tooth so the internal root canal system can be reached.

Clean and shape the canals

Inflamed or infected pulp tissue is removed.

The canals are carefully cleaned, disinfected and shaped.

Fill the root canal system

Once adequately prepared, the canals are sealed with a root filling material, commonly gutta-percha.

Restore the tooth

The tooth requires a suitable restoration after root canal treatment.

Depending on the remaining tooth structure, this may involve a filling, onlay or dental crown.

How many appointments does a root canal take?

Root canal treatment may sometimes be completed in one appointment.

Other teeth require multiple visits.

The number of appointments depends on:

  • The tooth being treated
  • Number and complexity of the canals
  • Presence of infection
  • Previous root canal treatment
  • Symptoms
  • Whether additional time is needed for disinfection
  • The final restoration required

A temporary filling may be placed between visits when treatment is being completed over multiple appointments.

Does root canal treatment hurt?

Local anaesthetic is used to make the procedure comfortable.

A tooth that is severely inflamed or infected can occasionally be more difficult to anaesthetise, and additional techniques may be required.

Some tenderness after treatment can occur, particularly if the tooth was painful beforehand.

Contact us if pain is severe, worsening or does not settle as expected.

Root canal treatment should not be promoted as universally pain-free, but modern anaesthesia allows most treatment to be performed comfortably.

Why is rubber dam important?

Rubber dam isolation is an important part of root canal treatment.

It helps:

  • Keep saliva away from the tooth
  • Reduce contamination from oral bacteria
  • Protect the mouth from small instruments
  • Contain disinfecting solutions
  • Provide a clean working environment

For these reasons, rubber dam is routinely associated with appropriate root canal treatment.

Will the tooth need a crown afterwards?

Not every root canal treated tooth requires the exact same restoration.

The decision depends on:

  • Which tooth has been treated
  • How much natural tooth remains
  • Size of existing fillings
  • Whether the tooth is cracked
  • Biting forces
  • The amount of structural support remaining

Back teeth often require greater protection after root canal treatment because they experience substantial chewing forces and may already have lost significant tooth structure.

A crown or onlay may therefore be recommended.

Front teeth with substantial healthy structure remaining may sometimes be restored differently.

What are the alternatives to root canal treatment?

If the pulp is irreversibly damaged, simply placing a normal filling does not remove the diseased tissue inside the roots.

The main alternative is generally extraction.

After extraction, the missing space may be:

  • Replaced with a dental implant
  • Replaced with a dental bridge
  • Replaced with a denture
  • Left without replacement in selected circumstances

The best decision depends on the condition and prognosis of the tooth as well as the consequences of removing it.

Can a root canal fail?

Yes.

Root canal treatment can provide long-term service for many teeth, but success cannot be guaranteed.

Problems can occur because of:

  • Complex root canal anatomy
  • Persistent or recurrent infection
  • A new cavity
  • A leaking or damaged restoration
  • A tooth fracture
  • Previously untreated anatomy
  • Other biological or restorative factors

If a root canal treated tooth develops a new problem, options may include retreatment, endodontic surgery, specialist assessment or extraction depending on the circumstances.

When might an endodontist be recommended?

An endodontist is a registered dental specialist with additional training in root canal treatment.

Referral may be considered when:

  • The root anatomy is particularly complex
  • Previous root canal treatment has failed
  • An instrument or other complication affects treatment
  • Surgical endodontic treatment may be required
  • The diagnosis is uncertain
  • The tooth requires a level of care better provided by a specialist

Referral does not necessarily mean the tooth cannot be saved.

It means the case may benefit from specialist expertise.

Toothache or facial swelling?

Severe dental pain or swelling should be assessed promptly.

Not every toothache requires root canal treatment, so diagnosis is important before deciding on treatment.

If you have facial swelling associated with difficulty breathing or swallowing, seek urgent medical care or call 000.

Root canal questions

What is a root canal treatment?

Root canal treatment removes damaged or infected pulp tissue from inside a tooth, cleans and disinfects the root canal system and seals the space.

How do I know if I need a root canal?

Symptoms can include persistent pain, prolonged hot or cold sensitivity, swelling or pain when biting. Some affected teeth have few symptoms, so examination and X-rays are often required.

Is root canal treatment painful?

Local anaesthetic is used during treatment. Some tenderness after treatment can occur.

How many appointments does root canal treatment require?

It may take one or several appointments depending on the tooth and clinical situation.

Will I need a crown after root canal treatment?

Possibly. The appropriate final restoration depends on the location of the tooth and how much healthy tooth structure remains. Read about crowns.

Why not just extract the tooth?

Extraction is a valid alternative in some circumstances. Root canal treatment may allow a restorable natural tooth to remain in the mouth. Read about tooth extractions.

Can an infected tooth heal with antibiotics alone?

Antibiotics do not remove infected or irreversibly damaged pulp tissue from inside the root canal system. Definitive dental treatment is usually required.

Can a root canal treated tooth get another infection?

Yes. Reinfection can occur and may require further treatment.

How long does a root canal treated tooth last?

There is no guaranteed lifespan. Long-term outcome depends on the root canal treatment, final restoration, remaining tooth structure, oral hygiene and other factors.

What is an endodontist?

An endodontist is a registered dental specialist with advanced training in root canal and related treatment.

Have tooth pain or been told you may need a root canal?

The first step is establishing what is happening inside the tooth and whether it can reasonably be saved. Book an assessment at Dental Seasons and we can examine the tooth, explain the findings and discuss root canal treatment, extraction or other appropriate options.
