Professional bleaching is the most common form of tooth whitening.
Your dental team will apply the whitening product to your teeth, using a specially made tray which fits into your mouth like a mouthguard.
The ‘active ingredient’ in the product is usually hydrogen peroxide or carbamide peroxide. As the active ingredient is broken down, oxygen gets into the enamel on the teeth and the tooth colour is made lighter.
Once your dental team has started this treatment you may be given the trays to take home and continue the treatment, or you may need more appointments with the team. This treatment can take around 3 to 4 weeks, depending on how long you keep the trays in your mouth each time, and how much whiter you want your teeth to be.
It is important to remember that only natural teeth will be whitened, and that any crowns, bridges or dentures you have will stay the same shade.
