Teeth can gradually darken as you grow older. They can also be made darker by bacterial deposits, food and drink, and habits such as smoking. Bleaching chemically lightens teeth, so that they look lighter and usually more attractive.
Bleaching is used to:
- Improve teeth if they have become discoloured with age;
- Remove stains caused by food and drinks such as tea,coffee,red wine and curry, as well as smoking;
- Remove stains under the surface of your teeth caused by certain antibiotics or stains caused by tiny cracks within the teeth.
Voco Perfect Bleach system
The system that we use, Voco “Perfect Bleach”, gives you complete control over the rate and the extent to which you lighten your teeth. The system comprises of discrete, custom-made trays which closely fit over your teeth into which you apply a small amount of the lightening material.
You then wear this for up to two hours per day and most results are achieved in about six weeks.
For some types of colour, such as tetracycline staining, the process can take considerably longer.
If you were to use the trays more frequently then rate of changing colour would increase but you could also induce sensitivity in the teeth but this sensitivity is easily remedied.
There are four ways in which this can be done:
This technique provides reliable results. The rate and extent of colour change will be controlled by you dependent on the amount that you use it. Normally one would use it for les than 2 hours per day and achieve good results in about 4-6 weeks.
It is important to be aware that only natural tooth will be lightened and so any existing restorations will stay the same colour. These may need to be replaced if the new shade of your teeth makes these crowns, veneers and fillings look unsightly.
