Whitening of teeth involves the use of bleaches to remove the stains which can accumulate over time.

The discolouration can be reversed using bleach gels in custom made close fitting trays, over either five nights or five three hour sessions.

There is sometimes a little sensitivity of the teeth whilst in treatment, this is only a temporary effect, and there is no harm to any of the tissues.

A single treatment will have an effect for a number of years, and can be "topped up" as required, re-using the original trays.
