Flash whitening is an in-office bleaching procedure in which a hydrogen peroxide gel is applied to isolated teeth and worked through three to four 15-minute cycles, roughly 45 to 60 minutes of chair time in a single visit, with reported shade improvement of 6 to 8 shades. A take-home tray version uses a weaker gel worn for 7 to 14 days. Shade stability is usually described in the 12 to 24 month range and depends on coffee, tea, wine and tobacco exposure. Crowns, veneers and fillings do not change colour, so visible restorations are assessed before treatment.
- 01The in-office protocol runs as three to four 15-minute cycles, about 45 to 60 minutes of clinical time in a single appointment.
- 02Reported shade improvement after one in-office session is 6 to 8 shades; the express variant takes around 30 minutes and does less.
- 03Light activation is the contested part of the protocol: a meta-analysis of 21 randomised trials found no significant difference in colour change or in the risk and intensity of tooth sensitivity between light-activated and non-activated in-office gels (PubMed 29289725).
- 04Take-home trays use a lower-concentration gel worn for 7 to 14 days and are the usual maintenance route between in-office sessions.
- 05Whitening gel does not change the colour of crowns, veneers or composite fillings, so restorations in the smile line are planned separately.
/ Flash Whitening Basics and Treatment Types

If you’re looking for a fast and effective way to brighten your teeth, Flash Whitening offers one of the most trusted solutions in cosmetic dentistry.
