Tooth Whitening:

  

Tooth whitening (bleaching) is a fast, simple and affordable way of lightening most teeth.   Teeth tend to stain, discolour or "yellow" over time due to a variety of causes.   Causes of discolouration include aging, coffee or tea consumption, tobacco, tetracycline (antibiotic) staining, and old fillings.   

Tooth whitening involves the use of a lightening gel (carbamide peroxide) in a custom bleaching tray which is made by the dentist to fit over your teeth.   The tray is normally worn over your teeth while you sleep, and generally the process takes 10 to 14 days, although changes will be seen after a few days.

Tooth whitening acts by the release of oxygen from the carbamide peroxide gel, which enters the enamel surface of the tooth and bleaches the discoloured substances.

Following whitening of the teeth, the teeth will always be lighter than they were. However, some patients may need periodic re-whitening for one or two nights every six to twelve months.
