Tooth whitening is a very popular, non-invasive, conservative approach to enhance and brighten an individual's smile. The procedure can reverse the effects of years of stain deposition from coffee, tea, tobacco, red wine and other (natural or artificial) food colouring.

It can be done "in office" or "at home" or by a combination of the two methods.

The "in office" method is faster as it allows the dentist to employ a higher (35%) concentration of the whitener.

With the "at home" technique a 10-16% concentration is applied to the teeth via a custom made tray that fits accurately over the teeth. Typically one hour's daily application for two weeks produces visible improvement in the majority of cases, but some cases will take longer.
