Professional in-office teeth whitening is the most popular cosmetic dental procedure in the world today. Unlike home-use whitening systems that incorporate low-dose bleaching agents, in-office whitening (also known as power bleaching, power whitening, professional whitening or chair side whitening) takes place under carefully monitored conditions which allow for the safe, controlled, pain-free use of a relatively high concentration of bleaching gel – yielding results that are visible immediately.
Advantages of office bleach
No other teeth whitening procedure produces faster results.
This is the safest form of tooth bleaching.
Gum and tooth sensitivity (formerly drawbacks to in-office bleaching) are more controllable today due to thicker peroxide gels (that don't soak into the teeth as much as previous gels) and the use of desensitizers such as potassium nitrate and fluoride.
Stains that are best removed in office bleach
Chairside whitening removes organic stains or discolorations primarily caused by:
Aging. Over time, the teeth darken with a yellow, brown, green or grey cast (which may be due to heredity and/or eating habits). Yellowed teeth tend to whiten most readily.
Consumption of certain foods (notably coffee, red wine, sodas and dark-colored vegetables an
Are you suitable candidate for teeth whitening
This procedure is not suitable for those with the following conditions:
Tooth and gum hypersensitivity. To avoid a hypersensitive reaction, your dentist is likely to recommend take-home bleaching trays with a low concentration of carbamide peroxide – which is not as potent as hydrogen peroxide.
Deep and intractable staining. Some stains are resistant to high-concentration in-office bleaches. In such cases, dentists may recommend a supervised regimen of intensive take-home bleaching or alternatives to hydrogen peroxide bleaching such as bonding, crowns and porclien veneers.
Teeth that have become transparent with age. This is particularly true of the front teeth, which are thin to begin with.
