Innovations in Tooth Bleaching: Deep Bleaching

Last Updated 8/6/2006 - A new bleaching technique has emerged called Deep Bleaching. The name is coined after the inventor, Rod Kurthy, a full-time practicing dentist who spent hundreds of hours in clinical testing of this technique. Rod Kurthy is also a primary clinical product tester for several major dental product manufacturers. The Deep bleach technique is so powerful, it can whiten tetracycline stained teeth and, in some occasions, even veneered teeth.




This procedure involves two power bleaching appointments a week apart, and a home tray in between. For the power appointments, a powerful 9% hydrogen peroxide solution is used and a 16% carbamide peroxide solution is used for the home tray. Depending on the case on the desires of the dentist, on the second visit either the same 9% Hydrogen Peroxide is used, or DeepBleachingMax is used, which is 27% Hydrogen Peroxide. D-Senz-2 is applied after the power bleaching process to help de-sensitize the teeth and seal them from decreased rebound. However, like any teeth whitening procedure, teeth sensitivity is expected with this process. Remember, even with over-the-counter bleaching products, acute painful sensitivity can become an issue.

The split-arch clinical studies showed that nearly all felt sensitivity on the side without desensitizers, but two out of three felt no sensitivity on the other side where the desensitizers were used. The one out of three that did feel sensitivity only felt between 8% - 10% of what they felt on the other side of their mouths. But it is very important for any reader to understand that this does not mean there will never be pain. Some patients are so sensitive that they can't even handle whitestrips on their teeth for than two or three minutes without pain. So even at only 10% of the typical sensitivity, these super-sensitive patients may still feel some dismofot.

No light is necessary with this technique. Tests have been done with and without light activation and no differences have been seen. To support this contention, researchers at CRA have consistently stated that bleaching is a function of the concentration of the bleach and the length of time that the bleach stays on the teeth. Additionally, they contend that a light has minimal to no effect on the bleaching process.

In some cases, porcelain veneers can be revitalized with the deep bleach technique. Sometimes the tooth structure under a veneer can darken over time (over 10 years) which can cause a significant shade difference. A cosmetic dentist usually replaces the veneer when this happens. However, since natural tooth structure is accessible through the back of a veneeer, it is possible to create "brighter" looking veneers with deep bleaching.

Rod's Deep Bleach technique is still very new to the dental community. Not every dentist offers this service, so do your research. Expect to pay up to $1,500 for this procedure.

The system is now being sold under the name KoR Whitening Deep Bleaching.
