What is Root Canal Treatment and when is it needed?

Root canal treatment is a dental procedure concerned with the prevention, diagnosis and treatment of a damaged pulp/nerve. There are two main reasons why pulp inside the tooth dies:

  • Infection of the tooth: An untreated cavity may lead to inflammation and infection of the pulp. This can be dangerous when the infection spreads to the surrounding bony structure.
  • Trauma to the tooth: Chronic irritation, multiple fillings and trauma to the tooth will evoke a pulpal reaction and can lead to infection.

When the pulp is diseased or injured, the pulp tissue dies. Root canal treatment is a safe and effective way to save your tooth before it’s too late.

  1. First, an opening is then made through the crown to access the canal.
  2. The damaged pulp is then removed and the root canal is cleaned.
