The two professional systems available for tooth whitening are the in-office power whitening and the take-home whitening kits.
The in-office technique usually takes approximately one hour and utilises a more powerful whitening agent and light source. This is ideal for the busy individual who does not have time to use at-home kits.
The at-home technique involves filling whitening trays with gel, which fit around the teeth. This type of technique usually takes 7-10 days to recreate the result of the in-surgery whitening.
