A Deep Dive into Restoring Your Smile

Internal bleaching is a specialized teeth whitening procedure designed for teeth that have undergone root canal treatment or have become non-vital due to trauma. Unlike conventional external bleaching methods that focus on the exterior of the tooth, internal bleaching targets discolouration from within the tooth structure.

The Science Behind the Discolouration:

Teeth possess thousands of minute dentinal tubules that radiate outward from the nerve center. When a tooth’s nerve dies – rendering the tooth non-vital – remnants from the degenerated nerve and blood particles accumulate within these tubules. This accumulation can cause an intrinsic staining of the tooth, which presents as a discolouration visible from the outside. It’s this intrinsic staining that standard external bleaching methods cannot correct.

The Procedure:

Preliminary Cleaning and Sealing

To ensure the efficacy of the treatment, the tooth's interior is first meticulously cleaned. The root canals, which have previously been treated, are sealed off to prevent any leakage of the bleaching agent into them.

Application of the Bleaching Agent

The bleaching gel, which contains an oxidizing agent, is then carefully introduced into the tooth's pulp chamber. This gel works similarly to external bleaching agents but is designed to act from the tooth's inside, addressing the intrinsic staining.

Optional External Whitening

In cases where a more holistic whitening effect is desired, internal bleaching can be paired with conventional external teeth whitening methods for a complete smile transformation.

Why Opt for Internal Bleaching?

Root canal therapy can save a tooth, but post-treatment discolouration can be a cosmetic concern. Studies indicate that approximately 10% of patients are dissatisfied with the appearance of their tooth after a root canal procedure. Internal bleaching provides a solution to this issue, helping restore the tooth’s natural shade from the inside out and ensuring a uniform smile.

Is It Right for You?

If you’ve experienced tooth trauma or have had a root canal and are noticing that the treated tooth is darker than its neighbours, internal bleaching might be the solution you need. It’s a targeted approach that focuses on restoring the beauty of individual teeth that have been compromised due to internal factors.
