Internal tooth whitening is an innovative and effective procedure designed to restore the aesthetic appearance of root-treated teeth. Tooth discoloration is a common concern, especially for those who have undergone root canal treatment. In internal whitening, a whitening agent is applied inside the tooth, helping to restore its original color and shine. This procedure not only improves color but also boosts patients' confidence, as healthy, attractive teeth are essential to a beautiful smile.
Differences Between Internal and External Whitening
Tooth whitening is available in two main types: internal and external whitening. Both methods aim to brighten teeth and improve their appearance, but the techniques and approaches are different.
-
Procedure Method
- External Whitening: In this method, the whitening gel, which usually contains hydrogen peroxide or carbamide peroxide, is applied to the outer surface of the teeth, either by a dentist or as part of a home kit.
-
- Internal Whitening: In this in-office procedure, the dentist places the whitening agent inside the tooth, specifically for root-treated teeth where external methods may not effectively address discoloration.
-
Application Area
- External Whitening: Suitable for natural teeth to remove external stains caused by coffee, tea, or smoking.
- Internal Whitening: Specifically recommended for root-treated teeth with internal discoloration, particularly when the dentin layer within the tooth has darkened.
-
Results and Effectiveness
- External Whitening: Results are usually immediate, with noticeable color change, but may gradually fade without good oral hygiene.
- Internal Whitening: Allows the dentist to monitor color changes during treatment for optimal results, often providing longer-lasting effects as it targets deeper discoloration within the tooth.
-
Safety and Comfort
- External Whitening: Temporary sensitivity may occur, though the procedure is safe when instructions are followed.
- Internal Whitening: Also safe and generally painless as the whitening agent is applied inside the tooth, sparing the enamel.
-
Cost and Availability
- External Whitening: Prices vary, with professional in-office treatments typically more expensive than home kits.
- Internal Whitening: Generally more costly due to its complexity and the need for professional application.
| Feature | External Whitening | Internal Whitening |
|---|---|---|
| Method | Surface Whitening | Internal Chamber Whitening |
| Application | Natural Teeth | Root-Treated Teeth |
| Results | Immediate, fades over time | Long-lasting, deep discoloration |
| Safety | Temporary Sensitivity | Minimal Discomfort |
| Cost | Varies; Home kits cheaper | Higher; requires dental expertise |
Why is Internal Whitening Necessary?
Internal whitening is typically necessary for root-treated teeth that have discolored due to:
- Materials Used in Root Canal Treatment: Fillings or sealants used in the procedure can darken over time.
- Damage to Enamel: Thinner enamel post-treatment can lead to discoloration as it doesn’t reflect light well.
- Bacterial Presence: Bacteria in the tooth’s inner chamber can lead to darker stains and potential health issues if untreated.
Internal Whitening Procedure
The internal whitening process involves several steps, each essential for successful results:
-
Preliminary Examination
The dentist examines the tooth to ensure it’s in a suitable condition for whitening. If any issues with the root canal filling are identified, these are addressed prior to whitening. -
Application of Whitening Agent
Once cleared, a specialized whitening agent is placed inside the tooth. The agent oxidizes the stains, gradually lightening the tooth color. -
Replacing the Whitening Agent
The agent is replaced periodically until the desired shade is achieved, with the dentist monitoring progress. The procedure generally takes 1-2 hours, depending on the tooth’s condition. -
Procedure Completion
After achieving the desired shade, the tooth is sealed with a filling that matches the natural tooth color for a long-lasting and aesthetic result.
Technical Details and Benefits
- Long-Lasting Results: Internal whitening results are often longer-lasting than external methods due to the deep-reaching effects of the whitening agent.
- Excellent Aesthetic Outcome: This procedure provides a natural-looking, harmonious result that enhances patient confidence.
- Safety and Comfort: Internal whitening is generally pain-free and requires minimal discomfort, making it a comfortable solution for patients with tooth sensitivity.
