Your smile is important. It’s one of the first things people notice when they meet you, and a brighter, whiter smile can help you feel better about yourself and leave a lasting impression. Unfortunately, a multitude of factors conspire against you to stain your teeth. No matter how often you brush them, coffee, tea, red wine, colas, tobacco and even orange juice will slowly but surely turn your teeth yellow. It’s usually very gradual, so you don’t notice until the change is quite significant or until someone tells you.
Fortunately for you, science and technology have advanced to the point where you can undo years or even decades of staining in as little as an hour. This is a cosmetic procedure that is best administered by trained professionals. The best way to perform teeth whitening is to use a proper whitening agent (that is, an effective whitening gel) and an appropriate whitening accelerator. The safest and most practical accelerator is an LED lamp emitting cold blue light with a wavelength of around 465 nanometers. This wavelength of light is ideal for activating the gel and accelerating the whitening process.
