Walking Bleach
Walking bleach is an older dentist-administered treatment for whitening discolored teeth. Combining sodium perborate and
H2O2, the walking bleach is applied by the dentist, and the patient carries on with normal activities. It usually takes 24 hours for full results to occur, and
patient communicate with the dentist's office 3-7 days later for an update on the bleaching progress, and possibly to schedule re-treatment. This method is
no longer a preferred route, especially compared to today's quicker, cheaper bleaching methods that provide immediate results.
