Discoloration of teeth results from all the mentioned causes: 1) Decomposition of the pulp - breakdown products of hemoglobin and pulp proteins create dark pigments, 2) Filling materials - amalgam, silver points, and some sealers cause metallic discoloration, 3) Hemorrhage following pulp extirpation - blood breakdown products penetrate dentin tubules causing dark staining. Other causes include medications (tetracycline), fluorosis, aging, trauma, and certain foods/beverages. The type and cause of discoloration determines the most appropriate treatment approach.

Key features: 1) Dentist provides custom trays and bleaching gel, 2) Patient applies treatment at home under professional supervision, 3) Uses lower concentrations (10-15% carbamide peroxide) for safety, 4) Extended contact time (6-8 hours) compensates for lower concentration, 5) Also called tray bleaching or home bleaching.
