Root Canal Procedure: A Step-by-Step Guide

Root Canal Procedure: A Step-by-Step Guide

When a cavity extends deep into your tooth, reaching the nerve, a simple filling won’t suffice. Instead, you’ll need a root canal to save the tooth. Let’s explore the process of repairing and preserving a damaged or infected tooth through a root canal:

1. Preparation: Isolating the Area

• The dentist begins by placing a rubber dam around the affected tooth. This ensures a dry environment during the procedure and prevents you from swallowing or inhaling any chemicals used.
• If there’s an associated dental abscess (a pus-filled swelling), the dentist may drain it during this step.

1. Accessing and Cleaning the Roots

   • Using a dental drill, the dentist opens the tooth through the crown (the top part) to access the pulp chamber and root canals.
   • The infected pulp (nerve tissue) is carefully removed.
   • The root canals are then cleaned and enlarged using a series of small files. This step may take several hours and may require multiple visits.
   • The number of roots in the tooth determines the complexity and duration of the treatment:
     • Front incisors and canines usually have a single root with one canal.
     • Premolars and molars (chewing teeth) have 2 or 3 roots, each containing 1 or 2 canals.

2. Lubricating and Shaping the Canals

   • The dentist uses rotary files and hand files to shape the canals, ensuring they are regular and ready for filling.
   • An apex locator machine helps locate the root tip (apex).
   • Hypochlorite, a cleaning solution, disinfects and lubricates the area.
   • Ultrasonic streaming agitators further enhance cleaning.

3. Drying and Disinfection

   • Paper points are used to dry the canals thoroughly.
   • EDTA (a liquid) opens up blocked channels inside the canal, allowing better cleaning.
   • Agitation and cleansing continue to ensure optimal disinfection.

4. Filling the Canals

   • Gutta-percha, a rubber-like material, fills the cleaned canals.
   • A down packer condenses the gutta-percha, ensuring a snug fit.
   • Backfilling completes the process.

5. Sealing and Restoration

   • The tooth is sealed to prevent reinfection.
   • If necessary, a crown may be placed to protect the root-filled tooth.

Remember, root canal-treated teeth are more prone to breakage, so follow your dentist’s advice for long-lasting results. 😊🌟
