Custom bleaching trays are created for each arch by taking an alginate impression. The impressions are poured up in stone and a custom-made tray if fabricated. Carbamide peroxide is the agent used to create the bleaching effect.
A small application of this gel is placed in each of the trays and patients wear the trays 30-60 minutes each night until desired effects are achieved. Fluoride should be used to aid in decreasing sensitivity as sensitivity is one of the possible side effects of tooth whitening.
Only natural tooth will exhibit a shade change, porcelain crowns or bondings on teeth will not change color. Ask your dentist today if you are a candidate for tooth whitening.
