Teeth whitening treatment uses a special whitening gel, applied directly to your teeth, to improve the shade of your natural teeth.
The gel is placed into a whitening tray, which is a bespoke tray designed to fit over your teeth. Wearing the tray brings your teeth into contact with the whitening gel.
The exact gel used, and the length of time it is used for, depends on the treatment you use.
Whitening treatment involves wearing your trays, with gel inside, for a number of weeks. The length of treatment, when you wear your trays and how often all depends on your precise treatment.
