Teeth Whitening in Miami Lakes
In the blossoming world of cosmetic dentistry, teeth whitening reigns supreme! Universally valued by men and women alike, whitening (or bleaching) treatments are available to satisfy every budget, time frame and temperament. The long and the short of it is that teeth whitening works. Virtually everyone who opts for this cosmetic treatment will see moderate to substantial improvement in the brightness and whiteness of their smile. However, teeth-whitening is not a permanent solution and requires maintenance or "touch-ups" for a prolonged effect.
The five factors are:
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.
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. We accomplish this action without the need for an expensive, custom tray.
Peroxide activity increases with temperature, releasing more of its powerful hydroxyl radicals than would occur at lower temperatures.
The longer you expose your teeth to a combination of peroxide, light, heat and pressure the whiter your teeth will get â€” 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.
