Root canal

What exactly is a root canal?

Also known as endodontic treatment, this is a common dental procedure used to treat infection of the root canal system at the centre of the tooth. The infection is caused by bacteria that already live in the mouth and are able to penetrate the tooth because of decay, leaky fillings or damage from trauma, such as a fall.

Why choose a root canal?

  • If a tooth is infected it may have to be removed. A root canal can help you avoid this.
  • A root canal can cure toothache, and help you keep your tooth for many years.

What does root canal treatment involve?

The procedure is normally carried out under local anaesthetic. The inside of the infected tooth is cleaned using special instruments and rinses. To help keep your tooth clean during the procedure, most dentists use a rubber dam (a rubber sheet held on a frame and fastened to your tooth/teeth with a special clamp).

Is root canal treatment safe?

Your dentist is highly trained and will make sure the procedure is very safe. As you can imagine, root canal treatment is a very skilled procedure which takes time to complete. Rare complications can include broken files or damage to the roots caused by the files or drills used.
