Stained teeth can frequently be whitened using at home bleaching trays that we fabricate in our office. Tea, red wine, coffee and tobacco are all agents that can stain teeth. The bleach that we use contains carbamide peroxide in a gel form that is placed in a custom tray that you wear at night.
Typically, after seven days your teeth will lighten several shades. You can then touch up your teeth every so often with the trays and replacement syringes of bleaching gel.
