Quick Answer

For endodontically treated teeth with discoloration, the walking bleach technique with Opalescence Endo is a predictable in-office method. Follow the steps below to achieve successful internal bleaching.

Why Walking Bleach Works

The walking bleach technique is a proven method for whitening non-vital teeth from the inside out. It involves placing a bleaching agent inside the pulp chamber and sealing it for a period, allowing the agent to diffuse through the dentin and lighten the tooth structure.

Opalescence Endo is specifically formulated for this procedure, providing a controlled release of hydrogen peroxide that is effective yet minimizes the risk of external root resorption when used correctly.

This technique is ideal for teeth that have darkened after root canal therapy, trauma, or the use of certain medications. It offers a conservative alternative to crowns or veneers, preserving natural tooth structure.

Important Considerations Before You Start

Before beginning any internal bleaching procedure, confirm that the root canal treatment is successful and the tooth is free of any pathology. A proper coronal seal is essential to prevent microleakage and ensure the bleaching agent stays in the chamber.

Assess the shade of the discolored tooth and discuss realistic outcomes with the patient. While walking bleach is highly effective, the final result can vary depending on the cause and severity of the discoloration.

Remember to protect the gingiva and adjacent teeth with a rubber dam and a suitable barrier material to prevent any soft tissue irritation from the bleaching agent.

Step-by-Step Application of Opalescence Endo

  1. Step 1: Assess and Prepare: Evaluate the tooth's root canal quality and ensure it is properly sealed. Remove any existing composite or temporary filling to access the pulp chamber. Check that the root canal filling is intact and free of voids before proceeding.
  2. Step 2: Protect Surrounding Tissues: Apply a rubber dam to isolate the tooth. Place a protective barrier, such as a light-cured resin, over the gingiva and adjacent teeth to prevent contact with the bleaching agent. Ensure the barrier covers all soft tissue to avoid chemical burns.
  3. Step 3: Place the Bleaching Agent: Using a suitable applicator, place Opalescence Endo gel into the pulp chamber, filling it completely. Avoid overfilling to prevent pressure buildup. Use a clean applicator and avoid trapping air bubbles in the gel.
  4. Step 4: Seal the Chamber: Seal the access opening with a temporary filling material, ensuring a tight seal to keep the gel in place and prevent leakage. Check the seal for any gaps that could allow the gel to escape.
  5. Step 5: Recall and Evaluate: Schedule a follow-up appointment in 3-7 days. Remove the temporary filling and gel, evaluate the shade, and repeat the procedure if necessary until the desired result is achieved. If no improvement is seen after two applications, reassess the tooth's condition and consider alternative treatments.
