Most often, patients present to our practice complaining of sore jaw, toothache, swelling, or tenderness, At this stage a root canal is likely to save the tooth from further damage.

What are the signs that a root canal is needed?

Sometimes no symptoms are present; however signs to look for include:

  • Severe toothache pain upon chewing or application of pressure
  • Prolonged sensitivity/pain to heat or cold temperatures
  • Discolouration (a darkening) of the tooth
  • Swelling and tenderness in the nearby gums
  • A persistent or recurring pimple on the gums

What happens during the procedure?

Before having root canal treatment, you will be given a local anaesthetic. This means the procedure shouldn’t be painful, and should be no more unpleasant than having a filling. A rubber sheet (dam) is then placed around the tooth to ensure it is dry during treatment. The dam will also prevent you swallowing or breathing in any chemicals the dentist uses.

The root canal system is then accessed through the crown of the tooth and special instruments are used to clean and shape the inside of the tooth then these space are filled to prevent further infections. This part of treatment may take several visits to complete depending on the number of canals and the complicity of the internal anatomy.

Once the Root Canal Therapy has been completed, the tooth is often left weak and prone to breaking. This is the reason a Dental Crown is required to restore the structure of the tooth and prevent irreversible damage. If a crown is not placed, the tooth may fracture in a way that compromises the integrity making it impossible to repair it. Unfortunately tooth removal will be the only option in this case. Find out more about Dental Crowns.

What happens if I don’t have root canal treatment?

If Root Canal Therapy is not done, and the tooth is left untreated, this will affect the soft tissue around the tooth causing infection and an abscess to form and may affect other teeth around it. The affected tooth will eventually need extraction due to the pain from the infection.  To fill the gap, a denture, bridge or an implant will be required.
