At-Home Tooth Whitening

The dentist constructs special fitting trays from individual models of the patient's upper and lower teeth. A small amount of oxidizing gel is placed on the inside surface of each tray by the patient and worn overnight for about eight nights.

Can all the teeth be whitened?

The whitening process can work on all natural teeth, although the degree of whitening will depend on age and the initial colour of the teeth. Any 'man made' material used on the teeth, such as crowns, veneers and fillings is not affected. In rare cases when teeth have been badly discoloured as a result of using antibiotics in childhood, whitening alone will be ineffective. More extensive cosmetic work will be required to achieve the effect.

How long will whitening last?
The effects will last up to three years, gradually diminishing over time. It is unlikely that your tooth colour will revert totally to its original shade. Of course, if you pay attention to oral hygiene, avoid heavily stained food and drinks as well as heavy smoking, you will prolong the effect.

Safety

Tooth whitening is safe. The active materials have been used for many years, with no indication of any harmful effects.
