With our revolutionary KöR-Seal™ Trays, and specially formulated KöR Whitening gels, we are able to achieve 6+ hours of active whitening instead of the common 25-35 minutes.
This will condition every patient’s teeth so that they become permeable to bleaching factors (whitening byproducts of peroxide). The more conditioned and permeable teeth are to bleaching factors, the better they whiten. We have several years of research behind us, and the developer, Dr. Rod Kurthy, has personally seen the system through development and clinical testing every step of the way.
When followed appropriately, KöR Whitening training material and videos ensures “get it right” accuracy. Add to all of this our unique refrigeration process, not to mention the thousands of dental professionals who are singing the praises of KöR’s reliability, our satisfaction guarantee, and you have every confidence that you’ll get it right all the time.

Unlike other whitening methods the KöR System is able to fully rejuvenate and restore teeth to their youthful ability to absorb bleaching factors. This is achieved by allowing pigments and stain molecules to be fully flooded by bleaching factors, thus thoroughly breaking down large stain molecules to ultra-small colorless and white particles.
The resultant conditioning and permeability of the teeth to bleaching factors facilitates easy, effective periodic at-home maintenance by patients, keeping the level of whiteness absolutely permanent, while still allowing patients to consume coffee, tea, red wine, etc.

Yes. Following the complete recommended system, in accordance with our training manual, is the only way to achieve whitening results that will fully satisfy you and your patients. As long as all steps are followed you will get a fabulous result every time.
No matter how small a step is, not following it may result in unsatisfactory results. The results of KöR Whitening are not due to a single “magic bullet,” but rather a complete series of technique steps that together with ideally-matched products, result in the amazing whiteness your patients expect.

Patients should understand there will routinely be some amount of regression after the whitening process. Technically, that regression is more accurately described as the color “normalizing” so that the teeth appear more natural.
Immediately after the active phase of KöR Whitening, and after any in-office whitening visit, patients will usually have a few nights of at-home whitening gel left. The patient should continue whitening every night until the whitening gel is gone. After this, or after Accelerated Maintenance, all patients should be directed to wear their KöR-Seal Trays, with whitening gel, a minimum of one night per month indefinitely.
If you have a particularly resistant patient, or someone who has teeth that absorb stain very quickly, or a patient who constantly consumes the most staining beverages possible, you may need to recommend a twice monthly Long-Term Maintenance program. In rare, very difficult cases, the patient may even require more than twice monthly maintenance. When patients need more frequent maintenance, daytime maintenance with KöR-Day also works well.
