How to get the smile of a lifetime with White Science.

Research has shown that there are five elements to successful teeth whitening. The more of these factors included in a bleaching treatment, the greater the results that treatment will achieve. These five factors are:

Peroxide | Light | Pressure | Heat | Exposure

Peroxide

This is the active ingredient in virtually all dental whitening products. It comes in many forms, but ultimately breaks down to hydrogen peroxide. The hydrogen peroxide reacts with light and oxygen to form hydroxyl radicals, which penetrate the tooth structure, breaking down stains into progressively smaller particles as they go. So far, so good. But peroxide is strong stuff, and can burn gums and cause tooth sensitivity. Typically, this is dealt with simply by diluting the peroxide; the lower the concentration of peroxide, the fewer the side effects, but the less effective it is at whitening teeth. The main reason for the side effects is that the pH (degree of acidity or alkalinity) of peroxide is too far away from neutral. Some tooth bleach manufacturers artificially lower the pH of their peroxide to make it more stable. But this increases its side effects. There is a better way. The conversion of hydrogen peroxide to hydroxyl radicals can be accelerated and sustained by exposure to certain wavelengths of light, basically from about 400 to 560 nanometers. This is well within the safe visible light spectrum, far away from dangerous ultraviolet light. By exposing the teeth to light concentrated in this spectrum while the peroxide is on the teeth, the whitening action is accelerated and intensified, increasing the release of hydroxyl radicals, even with neutral pH peroxide.

Light

An advanced, spectrum-controlled light specifically developed for the SpaWhite process is positioned to apply its energy just outside of a clear lens positioned between the teeth. This unique, patented lens not only acts to guide the light into the peroxide, it also helps with delivering the next factor:

Pressure

Peroxide is of little value if it doesn’t get into the structure of the tooth. Mild pressure is required to accomplish this. Dentists apply pressure by molding a tray that is custom fit to your teeth. The peroxide gel is placed in the tray, and forced into place. SpaWhite accomplishes this action without the need for an expensive, custom tray.

Heat

Peroxide activity increases with temperature, releasing more of its powerful hydroxyl radicals than would occur at lower temperatures.

Exposure

The longer you expose your teeth to a combination of peroxide, light, heat and pressure the whiter your teeth will get — to a point. Peroxide eventually breaks down into water. It “wears out” rather quickly, and the more light and heat it is exposed to, the faster it wears out. So a balance must be struck between repetition of applications and exposure time.
