What is Root Canal Therapy?

Also known as endodontic treatment, this procedure involves treating the dental pulp at the centre of the tooth. The pulp contains the nerves and blood supply that keep the tooth healthy. When this area becomes diseased or injured—often due to deep cavities, a cracked tooth, or physical trauma—the pulp may become inflamed or infected.

If left unmanaged, the infection can lead to an abscess, causing significant discomfort and potential tooth loss.

Recognising the Indicators

While only a clinical examination and X-ray can confirm the need for treatment, common indicators associated with pulp infection include:

  • Persistent sensitivity to hot or cold temperatures.

  • Discomfort when biting or applying pressure.

  • Spontaneous toothache or throbbing pain.

  • Swelling or tenderness in the surrounding gums.

The Treatment Process

Root canal therapy is typically performed over one or two appointments:

  1. Diagnosis: Utilising digital imaging to assess the extent of the infection.

  2. Removal: Under local anaesthetic, the diseased pulp tissue is removed.

  3. Cleaning: The canals are thoroughly cleaned and sterilised.

  4. Sealing: The canals are filled and sealed with a biocompatible material to prevent further bacterial entry.

Is the Procedure Painful? There is a common misconception that root canal therapy is painful. In reality, the procedure is performed under local anaesthetic and is designed to relieve the pain caused by the infection. Most patients find the experience comparable to having a standard filling.

Restoring the Tooth

Because a root canal involves removing the tooth’s internal blood supply, the tooth can become more brittle over time. To protect the tooth from fractures, your dentist will often recommend a dental crown as a final restoration. This provides the structural support needed for normal chewing and function.

Aftercare and Prevention

Following treatment, the area may feel sensitive for a few days. This can usually be managed with standard over-the-counter pain relief as advised by your practitioner. Maintaining a diligent oral hygiene routine and attending regular clinical check-ups are essential for the long-term success of the restoration.

Important Information: All dental procedures carry risks. A consultation and clinical examination are required to determine suitability for any treatment. Individual results vary. Root canal therapy is a clinical procedure; inherent risks include the potential for reinfection or tooth fracture. The longevity of the treatment depends on clinical factors and patient maintenance. Any surgical or invasive procedure carries additional risks; before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
