Root Canal Procedure: Step-by-Step Treatment Guide

Wondering what happens during a root canal procedure? This detailed guide walks you through each step of the treatment, from start to finish.

1. How is a Root Canal Performed?

The root canal procedure follows a systematic approach to remove infected tissue and save your natural tooth.

Pre-Treatment Preparation

Before starting the root canal procedure:

  • X-rays taken – Show tooth structure and infection extent
  • Medical history reviewed – Check for allergies or conditions
  • Treatment plan explained – Discuss procedure and costs
  • Consent form signed – Confirm understanding and agreement

Anesthesia Administration

Making you comfortable:

  • Topical numbing gel – Applied to injection site
  • Local anesthetic injection – Completely numbs the tooth and surrounding area
  • Wait for full effect – 10-15 minutes for complete numbness
  • Test for numbness – Confirm no sensation before starting

Creating Access

Opening the tooth:

  • Rubber dam placement – Keeps treatment area clean and dry
  • Access hole drilled – Small opening made in tooth crown
  • Pulp chamber exposed – Reveals infected tissue inside
  • Initial cleaning – Remove visible infected material

Root Canal Cleaning

The core of the procedure:

  • Locate root canals – Find all pathways through tooth roots
  • Measure canal length – Use electronic apex locator for precision
  • Clean infected tissue – Remove all bacteria and damaged nerves
  • Shape the canals – Prepare spaces for filling material

Disinfection Process

Killing remaining bacteria:

  • Antimicrobial rinse – Flush out debris and bacteria
  • Ultrasonic cleaning – Advanced technology for thorough cleaning
  • Temporary medication – May be placed between appointments
  • Multiple rinses – Ensure complete disinfection

At Townsville Dental Clinic, we use the latest techniques for precise, comfortable root canal procedures.
