Root Canal Treatment

Root canal treatment in Woonona, what happens at each step

If a tooth throbs, stays sensitive to hot or cold, or has a swollen gum beside it, the inside of the tooth may be inflamed or infected. Your dentist can check it and explain your options, which may include root canal treatment. To book, call us on (02) 4284 4486 or book online.

Fees, private health benefits and third-party payment arrangements vary. Please confirm current details before relying on an option.

Root Canal

Saving a tooth that is inflamed or infected inside

Inside each tooth is soft tissue called the pulp. If decay, a crack or an injury lets bacteria reach it, the pulp can become inflamed or infected. Root canal treatment removes the affected tissue, cleans the inside of the tooth and seals it.

Your dentist explains your options, which may include removing the tooth, and what each involves. After root canal treatment your dentist may suggest a filling or crown to protect the tooth. For current fees, call us on (02) 4284 4486 or read Our fees. You can also see our Patient offers.

What happens inside the tooth

Each tooth has tiny spaces inside it called root canals, running from the crown down to the root. They hold the pulp, which is made up of nerves and blood vessels. Root canal treatment cleans, shapes and disinfects these canals and seals them to stop the infection and save the tooth, and the tooth is then restored with a filling or crown.

It is one of the treatments in our General Dentistry range.

Signs of infection

A root canal infection does not always cause symptoms straight away. Signs can include toothache or sensitivity, a pimple-like bump near the tooth where pus is building up, sensitivity to hot or cold, swelling near the tooth or jaw, and a tooth that gets darker in colour.

Make an urgent appointment with your dentist if you have severe pain or swelling. Similar signs can come from other problems, such as decay that needs Tooth fillings, so only a dentist can tell you what is going on.

The treatment steps

Root canal treatment usually takes a few appointments. The root canal procedure has several steps:

  1. Your dentist takes an X-ray and numbs the area with a local anaesthetic.
  2. They may put a rubber sheet, called a dam, over the tooth to keep it clean and dry.
  3. They make a small opening and remove the pulp.
  4. They clean, shape and disinfect the canals.

If more than one session is needed, the tooth is sealed with a temporary filling in between. When the canals are clean they are filled and sealed, and a filling or crown goes on top.

Getting ready for your visit

Before your visit, tell your dentist about any health conditions and medicines. Follow your treating team's preparation instructions, including any advice about eating and drinking. You may have some mild pain or discomfort afterwards, so ask what pain-relief medicines you can take, whether you can eat and drink normally and when you can go back to work or school.

If you feel anxious, ask whether IV sedation could help.

Complications to discuss

Antibiotics alone do not cure a root canal infection. Possible complications include too much or too little filling material, a small instrument getting stuck in the canal, injury to the root, or the tooth changing colour. In some cases treatment is not enough to treat a significant infection and the tooth has to be removed.

Your dentist explains the risks for your tooth before you decide, and regular Check-up and clean visits help them watch the tooth afterwards.

Removing the tooth instead

Removing the tooth is an alternative. If you decide against treatment or delay it, your tooth might need to be removed, and a removed tooth may need replacing, for example with a bridge or Dental implants. Delaying the final filling or crown after a root canal raises the chance of the tooth breaking, and Crowns and bridges explains what a crown involves.

When to get a tooth checked

Pain from a tooth can have several causes. These signs are a reason to have the tooth looked at promptly, because a tooth abscess will not get better on its own.

  • A toothache that does not settle: Pain that keeps coming back, or wakes you at night, needs a look.
  • Lingering sensitivity: Hot or cold makes a tooth ache for a long time afterwards.
  • A swollen or tender gum: The gum beside one tooth is swollen, or there is a pimple-like bump on it.
  • A darkened tooth: One tooth has changed colour, or has a deep crack or large hole.

What happens at your visit

Treatment can take more than one visit. Your dentist explains the plan for your tooth first so you know what each visit involves.

  • A check and X-ray: Your dentist looks at the tooth and may take an X-ray to see inside it.
  • Your options explained: You hear what the choices are and what each involves.
  • A plan for treatment: Treatment can take more than one visit, depending on the tooth.
  • Care afterwards: You hear how to look after the tooth and whether it needs a crown.

Frequently Asked Questions

Questions about Root Canal Treatment

These general answers can help you prepare questions for an individual conversation.

Root canal treatment aims to keep your own tooth when the tissue inside it is damaged or infected. It does not remove the whole tooth, so it is not the same as an extraction, even though some people hear the phrase "root removal" that way. Whether it suits you depends on an assessment of your tooth and your other options.

The Root canal treatment guide explains that a developed tooth can keep working without its pulp. Keeping the tooth does not mean leaving infection in place. Ask your dentist to point out the area on an image or model, so the explanation fits your tooth.

Treating the inside of the tooth and restoring its outside are separate parts of the plan. Our crowns and bridges page covers protecting or replacing teeth. Before you decide, write down your questions about appointments, fees and aftercare, and ask how realistic keeping the tooth is in your case. Treatment has limits, and your dentist should explain them as clearly as the intended benefit.
