Abstract
Night Guard Vital Bleaching (NGVB) or dentist-monitored bleaching technique is probably the most widely used bleaching technique because of its relative ease of use, low cost, safety and high success rate. There are many non-vital bleaching techniques available, all of which have one thing in common, usually a successful result in the procedure returning the discoloured tooth to its original colour and beyond that when required.
This article will give an overview of various home bleaching techniques: materials and regimens used, bleaching procedure and treatment of side-effects. In addition, it will review various in-surgery and at home techniques used for bleaching non-vital teeth.
