Teeth whitening is a cosmetic procedure that is used to make the surface of the teeth appear whiter. Although teeth whitening cannot turn the teeth brilliant white, it can be a very effective way of lightening the existing color, without causing any damage to the tooth’s surface.
The effects of teeth whitening are not permanent and can last anywhere from a few months to three years. The amount of time the effects last for varies between individuals, but, in general, the effects do not last as long if a person stains their teeth through smoking or drinking tea, coffee or red wine, for example.
Laser teeth whitening, also known as “laser bleaching” or “power whitening”, uses lasers to accelerate the bleaching effect of a concentrated gel applied to the teeth.
Teeth whitening costs more than other methods, but it’s also the closest you’ll get to “instant” teeth whitening. If quick results are your main concern, this could be the best professional teeth whitening method for you.
