# RE-ROOT CANAL TREATMENT

## Intro

Re-root canal treatment, also known as root canal retreatment, is performed when a previously treated tooth develops new infection or symptoms. The aim is to preserve the natural tooth by addressing unresolved issues.

This guide explains what re-root canal treatment is, who may need it, how it is performed, and what to expect afterward.

## What is re-root canal treatment?

Re-root canal treatment involves reopening a tooth that has already undergone root canal therapy. The canals are cleaned again to remove remaining or new infection.

The tooth is then resealed to reduce the risk of further problems.

## Who is a suitable candidate?

Re-root canal treatment may be recommended for patients who:

- Have persistent pain or infection after a root canal
- Develop new decay or cracks affecting the treated tooth
- Have incomplete healing seen on follow-up imaging

A thorough evaluation is required to confirm whether retreatment is appropriate.

## How is the procedure performed?

The existing restoration is removed to access the canals. Old filling material is taken out, the canals are cleaned and disinfected, and the tooth is resealed.

A new filling or crown is placed to restore function and protection.

## Treatment timeline

### *Before the procedure*

- Clinical examination and imaging
- Assessment of tooth structure and restorability

### *During the procedure*

- Removal of existing restoration
- Canal cleaning and disinfection
- Resealing of the tooth

### *After the procedure*

- Mild tenderness may occur
- Follow-up imaging may be recommended

## Recovery & aftercare

Post-treatment tenderness usually resolves within days. Proper restoration and good oral hygiene are essential to reduce the risk of reinfection.

## Possible risks & considerations

- Complex canal anatomy
- Reduced tooth strength
- Possibility that surgical treatment or extraction may still be needed

## Expected results

Re-root canal treatment aims to control infection and extend the life of the natural tooth when possible.

## Frequently asked questions

### *Is retreatment always successful?*

Success depends on the cause of failure, tooth anatomy, and overall tooth condition.

### *Is retreatment painful?*

Local anesthesia is used, and discomfort is usually manageable.

### *What if retreatment fails?*

Other options, such as surgical treatment or extraction, may be discussed.
