Awareness of health issues and quality of life has greatly increased during the past decade. In the past, someone whose teeth had turned dark had to live with the unpleasant reality; today, darkened (yellow, grey or brown) teeth can be treated simply, safely, quickly and inexpensively – by tooth whitening.

Teeth that have been darkened and stained can be lightened by whitening, a treatment that involves an effective combination of whitening gel and light activation in order to reach the desired tooth shade within a short period of time, without damaging the teeth at all. The active agent (hydrogen peroxide) penetrates the tooth and oxidizes the organic tissue that caused the discoloring.

Prior to whitening, it is important to undergo a dental hygiene treatment in order to remove stains caused by substances such as coffee, nicotine and food coloring, which may improve the state of the teeth even before they are whitened. The primary reason for the discoloration of the teeth include poor hygiene, consumption of large quantities of dark colored beverages (cola, tea, coffee, etc.), medications, smoking and genetic factors. The degree of lightening is not uniform, and is dependent on the source of the discoloration and its severity. As a result, sometimes a combination of several methods is required; in cases of severe discoloration, the treatment can be performed in a series of appointments. The dentist will be able to determine what the starting point will be, but only time will tell the degree of whitening that the patient will be able to achieve.

The tooth whitening process is composed of three primary methods:

1. Whitening in situ - performed at the clinic
Whitening at the clinic is done using an effective combination of whitening gel and light activation, so that the desired shade of tooth color is achieved within a short period of time. The active agent (hydrogen peroxide) penetrates the tooth and oxidizes the organic tissue which caused the discoloration. The whitening is done in one appointment at the clinic, and offers long term results.

2. At-Home Whitening – performed at home
At-home whitening involves the use of trays formed to fit to the shape of the teeth and the dental arch. The whitening agent used is less concentrated, and requires usage of a few hours per day. The result achieved is more exact and there are those who believe that it lasts longer.

3. Combination method – beginning at the clinic and continuing at home
In cases of severe discoloration, the treatment can be performed over a series of appointments at the clinic, and combined with treatment using trays at home.

Intra-coronal bleaching
Following a root canal, some teeth change color, adopting a darker, usually grey, tone. These teeth can be usually be bleached internally andor externally to their original color, avoiding the need for a crown in some cases.
