Root Canal Treatment – Endodontic Therapy

What is Root Canal Treatment?

Root canal treatment, also known as endodontic therapy, is a dental procedure that involves removing the infected or inflamed pulp (the soft inner tissue of the tooth containing blood vessels and nerves) from a tooth and sealing it with a root filling.

This is a process that may take several appointments. This treatment is necessary when the pulp becomes irreversibly inflamed or infected due to deep decay, cracks or trauma.

Indications for Root Canal Treatment

  • Severe toothache – Persistent or severe pain in the tooth, especially when biting down or applying pressure, can indicate an infected or inflamed pulp.
  • Sensitivity to hot or cold temperatures – If a tooth experiences lingering pain or discomfort after exposure to hot or cold foods and drinks, it may be a sign of pulp inflammation.
  • Deep decay or injury – When advanced decay or trauma has reached the nerve chamber of the tooth
  • Persistent dark discolouration of the tooth – A tooth may appear darker or discoloured if the pulp has died or become infected.
  • Abscess or pimple on the gum – The formation of a pimple-like area or abscess on the gum near the affected tooth

If left untreated, an infected or inflamed pulp can lead to further complications, such as an abscess, bone loss around the tooth, or the spread of infection to other areas of the body.

Root canal treatment is designed to remove the infected or damaged pulp, clean and disinfect the root canal system, and seal it with a root filling to prevent further infection and preserve the tooth. This procedure is typically followed by the placement of a large composite filling or crown to reduce the risk of tooth fracture and restore function.

It is essential to seek prompt dental attention if you experience any of the above symptoms, as root canal treatment can alleviate pain, prevent the spread of infection, and potentially save the affected tooth.
