Teeth whitening treatment involves a series of steps and lasts between an hour and an hour and a half, depending on the treatment:   The mouth is opened with a mouth opener and cotton swabs are inserted to reduce salivation. A wax gel is applied to the gums to protect them from the whitening product. A whitening gel is applied to the surface of the teeth. An LED lamp is switched on and placed in front of the mouth for the required time. Finally, you rinse and check the result.
