Root Canal Treatment

Helping Save an Infected or Painful Tooth

A severe toothache does not always mean the tooth needs to be removed. When the pulp inside a tooth becomes irreversibly inflamed or infected, root canal treatment may allow the natural tooth to be retained.

Why Might Root Canal Treatment Be Needed?

Deep decay
A cracked or fractured tooth
A large or failing filling
Previous dental treatment
Trauma
Bacterial infection

Possible Signs

Persistent or severe toothache
Pain when biting
Prolonged hot or cold sensitivity

Swelling
Tenderness
A pimple on the gum
Darkening of a tooth

What Happens?

After local anaesthetic, the root canal system is accessed. Inflamed or infected tissue is removed and the canals are carefully located, cleaned, shaped, disinfected, filled and sealed.

Depending on the tooth and its condition, treatment may require more than one appointment.

After Root Canal Treatment

The tooth needs to be appropriately restored. Depending on remaining tooth structure and chewing forces, this may involve a filling, crown or other protective restoration.

When Specialist Care May Be Appropriate

Some root canal treatments are more complex.

If Dr Fred considers that a tooth would benefit from specialist assessment or treatment, referral to an endodontist will be discussed.

Frequently Asked Questions

Is root canal treatment painful?

Local anaesthetic is used with the aim of keeping you comfortable during treatment. Some tenderness can occur afterward.

How many appointments will I need?

It varies according to the tooth and clinical situation. Some cases require more than one visit.

Can every infected tooth be saved?

No. Extensive structural damage, significant cracks or other factors can make extraction more appropriate.

What happens if I do not treat an infected tooth?

An untreated infection can persist or worsen. The appropriate options should be discussed after assessment.
