When decay or a crack reaches the nerve inside a tooth, the pulp becomes infected and the pain can be severe. A root canal removes the infection and keeps the tooth in place — a natural tooth, even a treated one, is always better than a gap.

What the treatment involves

The tooth is numbed completely, then an opening is made so the infected pulp can be removed from each canal. The canals are cleaned, shaped and disinfected, then sealed to stop bacteria getting back in. Because a treated tooth becomes more brittle, we usually finish by protecting it with a crown.

What is included

• X-rays to map the canals and confirm the diagnosis
• Full local anaesthesia so the treatment is not painful
• Removal and disinfection of the infected pulp
• Sealing and filling of the canals
• A crown to protect the treated tooth

Step by step

1. Examination and X-ray to confirm the nerve is affected.
2. The tooth and the area around it are fully numbed.
3. The infected pulp is removed and the canals are cleaned.
4. The canals are disinfected and sealed.
5. A crown is fitted to protect the tooth for the long term.

Aftercare

The tooth will be sensitive to biting for a few days while the tissue around the root settles — ordinary painkillers handle it. Avoid chewing hard food on that side until the crown is fitted, because an unprotected treated tooth can fracture. Call us if swelling appears or the pain increases rather than fading.
