The main difference between the teeth whitening gel offered by the dentist and the whitening products that can be used at home is the chemical composition of the bleaching materials on offer, and consequently the time required for the teeth whitening products to take effect. Generally, the teeth whitening gel used by dentists tends to be stronger than the bleaching gel on sale in shops.
