Whitening

Is tooth whitening safe? How does it work? Is tooth whitening offered by dentists all the same?

First and foremost, tooth whitening is considered safe and effective when performed under a dentist’s supervision. There has been years of research and studies to back up this claim.

The Dominant Chromophore Effect Theory, which dates back to 1991, explains how tooth whitening works. To make it simple to understand, the whitening agent aka hydrogen peroxide attacks the high electron density stain molecules and converts them to simpler structures. This structural change will de-colorize or fade away the stain molecules making the tooth appear whiter. This is a very simple model and theory, but ultimately, the whitening agent changes the tooth surface and alters its optical properties and henceforth the perceived colour of the tooth.

There are two major factors in determining the outcome of your whitening. It is the concentration of hydrogen peroxide and duration of application.

Not all whitening methods are created equal. Some dentists may offer a light system which facilitates increased free radical production while the heat speeds up the reaction rate of hydrogen peroxide.

So what is the best whitening system?

There are many whitening systems that are being offered by major companies. What I have found to be true is that many brands create whitening gels to increase its shelf-life and expiration. In order to increase the expiration of their products, they reduce the pH of the whitening gel. This unfortunately reduces the effectiveness of your whitening.

The KoR whitening system is exceptional unstable which is why they work! They need to be constantly refrigerated and are 100% aqueous base. Using the KoR whitening system with a custom tray will bombard the tooth surface and whiten more efficiently. Reducing the hydrogen peroxide concentration from 35% to 16% and shortening its application time to 20min on enamel 2x per treatment session provides a significant tooth-bleaching improvement. This whitening system that utilizes a custom tray delivers the safest, fastest and most satisfying results!
