Tooth Bleaching

Awareness to health and quality of life has gained great momentum in the last decade. Previously, a person whose teeth has darkened over time used to continue to live with that gloomy reality. Today, there is a simple, safe, quick and affordable solution for dark (yellow, gray and brown) teeth – tooth bleaching (also known as tooth whitening).

Dark, stained teeth may be brightened by tooth bleaching, which is done using an effective combination of a bleaching gel and light activation, reaching the desired tooth color within a short time, without any damage to teeth. The active substance, hydrogen peroxide, penetrates the tooth and oxidizes the organic tissue that caused staining. Tooth bleaching is considered one of the most highly demanded dental esthetic treatments.

Prior to teeth whitening, it is important to visit the dental hygienist to remove stains that have been caused by food coloring, nicotine, coffee, etc. Such treatment may improve the state of the teeth before starting the bleaching itself. The main reasons for darkening of the teeth are poor hygiene, drinking plenty of dark-colored drinks – cola, tea, coffee, etc., medications, smoking and genetics. The degree of brightening resulting from tooth bleaching treatment is not uniform, and depends on the staining source and severity. Therefore, sometimes it is necessary to combine several methods, and in cases of severe staining, the treatment may require multiple sessions. The dentist effectively knows what the starting point is, but only time can tell what degree of tooth bleaching the patient can reach.

There are three key methods of tooth bleaching

1. In-clinic bleaching

This type of tooth bleaching is done at the dental clinic, using an effective combination of a bleaching gel and light activation, and reaching the desired tooth shade within a short time. The active substance, hydrogen peroxide, penetrates the tooth and oxidizes the organic tissue that caused staining. The bleaching is done in a single session at the clinic and its results last a long time.

2. Home bleaching

Home tooth bleaching – using molds that have been especially prepared according to tooth trays. A less concentrated active substance is used, and daily use for several hours is necessary. The result is more precise, and considered by some to be longer-lasting.

3. Combined bleaching
starting at the clinic and continuing at home

Combined tooth bleaching is employed in cases of severe staining, in which the treatment may be done in multiple sessions at the clinic and complemented with molds for use at home.

Intracoronal bleaching (a.k.a. “Walking bleach”)

Teeth that underwent root canal treatment require more attention and care. In these cases, the tooth tends to have a grayish shade. These teeth may be brightened internally in addition to external bleaching, thus avoiding the need for a dental crown when unnecessary.
