TEETH WHITENING
How does tooth whitening work?
Carbamide peroxide removes stains by letting oxygen interact with the organic deposits that cause stains and then whitening the tooth surface to a whiter, brighter color, the color it was before it became stained. The process is effective in approximately 95% of people who have stains on natural teeth.
In most people, teeth become noticeably whiter when the appropriate whitening agent is applied to the tooth, which oxidizes the stains on the enamel´s surface. Dental whitening systems work best when tooth trays are custom made with reservoirs where the teeth are to be whitened. These reservoir areas are the most important aspect of properly fitted trays.
Most people notice a remarkable difference within 40 hours of cumulative treatment, though many respond in even less time. It is up to the individual how they want to span their treatment hours: some may wish for treatment to last only a few days, some may allow treatment last for several months. Because the whitening effects are cumulative, it makes no difference in the ultimate outcome how long an individual takes compiling his or her 40 hours of treatment.
What is the treatment procedure?
The dental team makes an impression of your teeth. From the models of your teeth, a custom-made flexible mouthpiece is made, which will hold the whitening agent next to the tooth surface. You apply a small amount of the whitening gel (about 1 ml) to the inside surface of the mouthpiece and fit it easily over your teeth. You can wear the mouthpiece as little as 30 minutes a day or up to 4 hours, depending on your personal preference. Most people see noticeable results after only a few hours of treatment.
