Your smile leaves a lasting impression on others. It is the first thing that people see when they look at you, so if you would like to make your smile more appealing. The Advanced Teeth Whitening System may be the answer for you. Until a couple of years ago, only dentists could perform teeth whitening treatments. Today, a lot changed, and teeth whitening became a cosmetic procedure, and can be done in a simple procedure, if done right! Doing it right means using a proper whitening agent (that is, a good hydrogen peroxide gel) and an appropriate whitening accelerator. The most practical accelerator is a LED lamp emitting cold blue light with a wavelength of around 465 nanometers. This wavelength of light is ideal for activating the hydrogen peroxide and accelerating the whitening process.
