Root Canal Treatment

Root canal treatment (also known as endodontics) can save a tooth that would otherwise need to be removed. It is needed when the soft tissue inside the tooth, called the pulp, becomes infected or inflamed. This usually happens after deep tooth decay, a cracked or broken tooth, repeated dental work on the same tooth, or an injury to the mouth.

Signs you may need root canal treatment

• Persistent toothache, especially when biting or chewing
• Sensitivity to hot or cold that lingers
• Swelling or tenderness in the gum near the tooth
• A tooth that has become darker in colour
• A small, pimple-like spot on the gum

Sometimes there are no symptoms at all and the problem is picked up on an X-ray during a routine check-up.

What happens during treatment

Root canal treatment has a reputation it doesn’t deserve. At the Dental Suite we use local anaesthetic so the tooth and surrounding area are completely numb, and most patients find the experience very similar to having a filling. For nervous patients we also offer The Dental Wand and IV sedation.

Your dentist will make a small opening in the tooth, carefully remove the infected pulp, then clean, shape and disinfect the root canals. The canals are then filled and sealed to stop bacteria getting back in. Depending on the tooth, treatment may be completed in one visit or over two appointments.

After treatment

The tooth may feel a little tender for a few days, which can usually be managed with over-the-counter painkillers. Because a root-treated tooth can become more brittle over time, we often recommend a crown to protect it and help it last for many years.

Why save the tooth?

Keeping your natural tooth is almost always the best option. Root canal treatment can help you avoid an extraction and the need to fill the gap with a bridge, denture or implant, so you can carry on eating and smiling with confidence.

Frequently Asked Questions

Q: Is root canal treatment painful?
A: The treatment is carried out under local anaesthetic, so you shouldn't feel pain during the procedure. Most patients find it no more uncomfortable than having a filling, and it usually relieves the pain the infection was causing.

Q: How long does root canal treatment take?
A: Most treatments are completed in one or two appointments, depending on the tooth and how many root canals it has. Your dentist will explain what to expect at your consultation.

Q: Will I need a crown afterwards?
A: Often, yes – especially for back teeth. A root-treated tooth can become more brittle, and a crown helps protect it from cracking so it lasts for many years.

Q: What happens if I don't have the treatment?
A: An infection inside a tooth won't heal on its own. Left untreated it can spread and cause an abscess, and the tooth may eventually need to be removed.
