costs of teeth bleaching

The standard fee for teeth whitening and teeth bleaching procedures is about $500 in most cases. Costs can vary depending upon the area of the country you live in and the type of whitening treatment you undergo. Laser teeth whitening is typically over $1000. for example. In-home tray bleaching can cost between $50. and $100. dollars for a total teeth whitening system. Store-bought whitening strips can cost as little as $25.

Teeth Whitening Procedure

Tooth whitening (or bleaching) is a simple, non-invasive dental treatment used to change the color of natural tooth enamel and is an ideal way to enhance the beauty of your smile. Because having whiter teeth has now become the number one aesthetic concern of most patients, there are a number of ways to whiten teeth.

Heat and light
The rate of chemical reactions can be increased by increasing the temperature, where a 10 8C rise can double the rate of reaction. The use of high-intensity light, for raising the temperature of the hydrogen peroxide and accelerating the rate of chemical bleaching of teeth was reported in 1918 by Abbot. Other approaches for heating the peroxide have historically been described to accelerate tooth bleaching, such as heated dental instruments. However, excessive heating
can cause irreversible damage to the dental pulp.

1. Type of bleach
The majority of contemporary tooth whitening studies involve the use of either hydrogen peroxide or carbamide peroxide. This latter material is an adduct of urea and hydrogen peroxide which on contact with water breaks down to urea and hydrogen peroxide. For  example, a 10% (w/w) carbamide peroxide gel would yield a maximum of 3.6% (w/w) hydrogen
peroxide. In general, the efficacy of hydrogen peroxide containing products are approximately the same when compared with carbamide peroxide containing products with equivalent or similar hydrogen peroxide content and delivered using similar format and formulations, either tested in vitro or in vivo.

Mechanism of tooth bleaching

Bleaching is a decolourisation or whitening process that can occur in solution or on a  surface. The colour producing materials in solution or on a surface are typically organic compounds that possess extended conjugated chains of alternating single or double bonds and often include heteroatoms, carbonyl, and phenyl rings in the conjugated system and are often referred to as a chromophore.
