Subsequently, they were advised to apply bleaching treatment for 20 minutes, once a day in the evening, using an adequate amount of teeth whitening gel in the moldable mouth trays. Following the treatment they were recommended to rinse their mouths with lukewarm water only. Whitening effect was evaluated after stabilizing the colour following the 10 day bleaching treatment.
