You may notice the difference after your first session. However, it is not advisable to use the bleach everyday but to leave a few days between treatments. Most people will see excellent results after just a few weeks.

When done professionally, with custom made trays, your tooth enamel and your gums are safe. Most people find the process straightforward and simple. There can be some sensitivity, but this is minimal. Your dentist can advise on how often and for how to bleach – and also suggest ways of reducing any sensitivity.

Whether bleaching your teeth or for teeth in general, to keep your teeth as bright as possible it’s best to avoid tobacco and dark or acidic foods. In addition, cut out drinks that stain such as tea, coffee, red wine and coloured soft drinks.
