Root Canal
Root canal treatment, or endodontics, saves a tooth whose inner pulp has become infected or inflamed, often through deep decay or injury. The dentist removes the damaged pulp, cleans and disinfects the canals inside the tooth, then fills and seals them. The tooth is usually restored with a filling or crown, relieving pain and avoiding extraction.

Root Canal — frequently asked questions
What is Root Canal?
Root canal treatment, or endodontics, saves a tooth whose inner pulp has become infected or inflamed, often through deep decay or injury. The dentist removes the damaged pulp, cleans and disinfects the canals inside the tooth, then fills and seals them. The tooth is usually restored with a filling or crown, relieving pain and avoiding extraction.
Is root canal treatment painful?
Root canal treatment is carried out under local anaesthetic, so it should feel similar to having a filling. Modern techniques mean most people find it far more comfortable than its reputation suggests. The treatment relieves the pain caused by the infection, though the tooth may be tender for a few days afterwards.
How long does a root canal take?
Root canal treatment is usually completed in one or two appointments, each lasting around 60 to 90 minutes, depending on the tooth and the number of canals it has. Back teeth have more canals and take longer. The tooth is then often restored with a crown.
Is root canal treatment available on the NHS?
Yes. Root canal treatment is available on the NHS as part of a standard treatment band, as it is needed to save a tooth rather than for cosmetic reasons. It is also offered privately, sometimes with specialist endodontic care. A dentist can explain the options.
