Root Canal Therapy

Root canal treatment

Root canal therapy involves the cleaning and sealing of the canal inside the root. In a healthy tooth this canal contains the nerve and blood vessels. In an unhealthy tooth the nerve is dying or has died and may be infected.  Root treatment allows us to preserve teeth that would otherwise have to be extracted.

Cleaning removes bacteria and shapes the canal for flushing with antiseptics prior to sealing. The weakened tooth then needs to be protected by a suitable restoration that will protect the weakened cusps and provide a good seal.

Root canal therapy is provided under local anaesthetic.  We generally aim to provide treatment in 1 visit to minimise the risk of re-infection, however 2 or 3 visits may be required to help ensure that the procedure is successful.

The tooth may feel slightly bruised or tender immediately after treatment and painkillers such as ibuprofen or paracetamol are recommended.

Fine metal files are used to shape the canals.  Even with extreme care there ia a small risk that files can fracture inside the very narrow canals.
